Are you the owner of the company or an employee of the company that created the K-light?
Ambrose
I am the designer. my job is to make sure the LEDs are very well cooled for max lumen per watt & that the electronics won't blow up when used...
have a look @ what happens to your light when your LED heats up...the DX version of the MShine has 3 thermal junctions & poorly matted ones at that...a 12w LED light could loss over 100lm easily just by adding more thermal junctions to the light case...
The more thermal junctions the less efficient heat transfer is, the hotter the LED junction becomes over time, the more light lost as heat...the less light you have...
its is great value for the price, but for me I like to have a driver & batterys that have been proven to work / last before I go off into the bush in the dark...I am sure many people will be happy with this light as it is...so I say go for it & buy buy buy...you can't go wrong at that price. But, I say buy off GEOMAN, as he has had his changed, closer to the spec I would be happy with, & has done so with feedback from user like me...
For me, I have modded mine...Thermal paste under the MCPCB, can lip, retainer & retainer thread, I used a IP68 cable gland, sealed the old cable hole, swapped out the untested driver to a tested AMC7135 in a 2.8A config, using 4 parallel wired 18650's, I have also 'stippled' the reflector for a smoother beam pattern & now I am happy, I love reflectors for the great beam they give ...for me this is a simple & reliable system with little to go wrong, that will get me home again...this is just MHO, people are free to make up thier own mind, as are you...
the DX version would have to be fully re-built to last any length of time just on the thermal side of things...let alone an un-tested driver & cheap batts...good for a cheapo modder to tinker...
good luck & enjoy

I have one of the Magishine lights from Geoman. HOLY SMOKES it's bright. I used to run to dinotte 200l's....this is quite a bit brighter. I still run one dinotte on my helmet, but I can't really see it unless I look a different direction than the bars are pointing. For 89 bucks shipped, it's really a screaming deal. If I was getting a couple lights with a 200 budget, I'd look no further. Heck, even if I had DOUBLE to spend, I'd get the magicshines and use the rest for other stuff.
Cool feedback; nice to hear Magicshine Led Lightset handily beats the Dinotte 200Lumen LED Lightset engine.
Magicshine High Intensity LED Lightset based on the newly updated SSC-P7 Seoul Semiconductor quad core chip LED which typically produces 700lm when current is driven thru the LED chip at 2800mA with a forward voltage of 3.6V and able to produce 90 lumens per watt of energy consumed.

Dinotte 200L-AA-S Bike Headlight is a basic solid entry level 200lumen lightset that uses conventional readily obtainable rechargeable/disposable "AA" batteries almost everywhere inexpensively.
Dinotte 200L-AA-S Bike Headlight retails for approximately $150 that yields approximately 75cents per lumen which is a great deal for a great and well known reputable LED Lightset thrower/illuminator. (link provided for your reference if needed):

The Magicshine MJ-808 retails for approximately $85 that yields approximately 12.8cents per lumen assuming approximately 666lumens, which is a great deal for a great throwing and illuminating LED Lightset that is giving the major light engine manufacturers a serious run for their money.

Even better still get an additional Magicshine LED Lightset, one for the helmet mount and one for the handlebar mount to double up on illumination; with one providing fixed illumination duties on the handlebars and the other one providing variable point to shoot flood/spill illumination on the helmet.::thumbsup:
Now of course if one needed, wanted or desired to construct a "betty killer" illumination setup on a budget, one could always combo a third Magicshine on the handlebar and aim one far away down the road in the distance and one closer in front of the bicycle wheel so as to provide general flood illumination in front of the wheel as well as provide generally more dedicated far away illumination in the distance.:thumbsup:
An added advantage of such a "betty killer" configuration setup would be the actual beam width would be naturally doubled also as well by having a double led lightset engine upfront as opposed to only a single lightset engine configuration setup.:thumbsup: :thumbsup:
The helmet mounted configuration would still be providing variable point to shoot flood/spill illumination on the helmet in its normally advantageous higher mounted illumination light source mounting position.
The combination of the three independent lighting sources (2handlebar/1helmet) even on the medium setting on the Magicsine LED Lightset (which is rated for 500lumens apiece) times three led light sources would add up to 1,500lumens; making the triple Magicshine LED Lightset a potential "betty killer" customized hybrid LED light configuration setup for less than $255.:thumbsup:
By running the Magicshine LED Lightset at only the medium(500lument) setting one can extend and optimize the total LED lightset total runtime to four hours or so; while still outputting sufficient the same 1500lumens lumination intensity.
Extending total light output plus 500Lumen High Power LED Lightset runtimes beyond fours is not only feasible but easily obtainable/affordable via cheap upgrades to the Li-Ion battery subsystem via an external battery pack. (link provided for your reference if needed):
Higher quality newer Polymer Li-Ion chemistry 9aH external battery pack $80.00(not composed of 18650 cells) but composed of two 3.7V 9aH Polymer Li-Ion cells(good for >500recharges) $8.88 per amp::thumbsup:
http://www.batteryspace.com/polymerli-ionbattery74v9ah666whwithpcb.aspx
For those concerned with their Li-Ion chemistry external battery pack catching fire one can always opt for the safer alternative of encasing the external battery pack in an accompanying enclosure.:thumbsup:
Higher quality newer Polymer Li-Ion chemistry 10aH external battery pack $140.00(also not composed of 18650 cells) but composed of four 3.7V 5aH Polymer Li-Ion cell(good for >500recharges) $14.00 per amp complete with trail tech connectors:
http://www.batteryspace.com/polymer...wh7arateinplasticenclsouretrial-techplug.aspx
For those concerned with their Li-Ion chemistry external battery pack catching fire one can always opt for the safer alternative of encasing the external battery pack in an accompanying enclosure while extending their total training run times for ultra-long illumination intervals an option might be.
Higher quality newer Polymer Li-Ion chemistry 25.2aH external battery pack $180.00(also not composed of 18650 cells) but composed of four 7.4V 12.6aH Polymer Li-Ion cell(good for >500recharges) $7.14 per amp complete with trail tech connectors::thumbsup:
http://www.batteryspace.com/polymerli-ionboxbattery74v252ah18648wh14aratewithtrial-techplug.aspx
The interesting thing with the mega capacity $180.00 25.2aH external Polymer Li-Lion battery pack would be capable of running all three Magicshine LED Lightsets in "betty killer 1500lumen mode" for approximately 7.5hours and still have the original three 4.4aH Magicshine Li-Ion batteries using them as backup for a total combined estimated run time of 11.5hours while still coming in well under betty budget busing led lightset and battery upgrade prices -->>$255 triple Magicshine MJ-808 plus $180 enhanced Polymer Li-Ion external battery subsystem equals $435 (29cents per lumen-->>1,500lumens) for the ultimate customized 1,500lumen "betty killer" running for up to 11.5 hours non-stop. :thumbsup: :thumbsup:
feel free to chime in with feedback response and/or ideas on the ultimate "betty killer" mode design.

-------------------------
from the above specified link for the MinJin and geomangear (
http://www.geomangear.com/index.php?...38paikjv9i1732
) one can derive:
The batteries are 7.4VDC lithium ion batteries with 4.4AH of capacity that drives the battery for about three hours
and the low brightness illumination setting is 30percent of total illumination (200 lumens) and the medium brightness illumination
setting is five hundred lumens.

Cheers, whew that was a heck of a review of high school electricity/physics review.
I actually had to crack open the books to review and practice.
--------------------------------------
Nice to review and know how to calculate the origins and answers from source derivative information but it all seems to check out as the answers seem to check out and are in what's called the "ball park" from what I have read on here in the mtbr and candlepower forums.

Review for Newly Purchased Magicshine MJ-808 P7 Based High Intensity LED Lightset Kit from Geoman is below as follows for your review and consideration:
Ordered the Magicshine P7 Based High Power LED Lightset Engine from Geoman. Order was processed promptly and accurately by Geoman. I am upgrading from a slightly dated led lightset in the form of a Princeton Switchback 1; so this will be a significant upgrade in terms of overall light lumen intensity.
I have seen some very good posted beamshots of the P7 Based Magicshine LED Lightset from a search on the internet; some very impressive looking illumination shots. I am willing to give the Magicshine MJ-808 high power led lightset the same chance I did with the Princeton Switchback I; as it looks like a great potential High Power Bicycle LED Lightset engine in the under one hundred dollar category.
As soon as I get the Magicshine after it ships from Geoman, I will factually share information of first product LED lightset impressions and in the field LED lightset impressions.
I got the Magicshine P7 Based High Power LED Lightset Engine from Geoman, the day after Columbus Day. Geoman by the way threw in the helmet mount as an added unexpected bonus to the Magicshine P7 based LED lightset kit. Many appreciative thanks to the Geoman or "G" Man for short.
I measured the Magicshine P7 based LED lightset head diameter dimension and it comes out to 1.5 inches and is 2 inches in lighthead depth for those concerned about it being bulky and/or heavy it definitely is lightweight as promised. The pushbutton on the back of the Magicshine LED lightset is about the size of a dime and is lit up with a green glowing LED when plugged into the 4.4aH Lithium Ion based battery pack.
The Magicshine lighthead bezel has a cool scalloped bezel design that makes it look very modern in styling. The Magicshine lighthead body behind the lighthead bezel has a concentric grooved cooling ridged design, with a professionally black anodized aluminum surface to help cool the LED lighthead.
The Magicshine lighthead power cord that goes to the external Lithium Ion based battery pack is a generous 45 inches long to allow the flexibility of mounting the battery pack wherever convienently desired.
If you enjoy the appearance and physical body design of the Lupine Tesla design this looks similar in most aspects and you will definitely like its cool, streamlined, sleek, lean body based looking LED Lightset design overall.
The external Lithium Ion battery pack is 2.75 inches height tall body and has side dimension of 1.5 inches on each side; so it is relatively small and lightweight with a nylon pouch included to allow one to wrap it underneath the handlebar near where the LED Lighthead is to be mounted on the handlebars.
The Magicshine P7 based lightset kit also comes with an AC adapter designed specifically to recharge the Lithium Ion based external battery pack rapidly/quickly and its DC output voltage is listed as 8.4VDC so as to enable the rapid recharging of the 7.4VDC external battery pack at a current rate of approximately 1.8aH equivalent to a recharging rate of 30ma per minute.
The external Lithium Ion battery pack only took about an hour to top off its charge and turn from the red glowing led on the recharging AC adapter to a green glowing led.
I followed the included yellow instruction sheet from the Geoman which clearly outlined the simple and self explanatory procedure to follow to cycle through the various five modes; the high, the med, the low mode intensities of illumination, along with the high frequency flash mode setting and the final strobe mode setting before going back to totally turning off the LED Lightset completely.
The two black latex mounting o-rings included are sized 1.5 and 2.0 inches respectively and the thickness of the two black latex mounting o-rings included are both 3/16 of an inch thick which looks like it can be bought at any local hardware store having black latex o-rings available or at geomangear for $4 for the small/large o-ring paired 1.5/2.0 inch o-ring set.
The included yellow instruction sheet also notes and mentions information regarding the lithium-ion battery should last approximately 300-500 charge/discharge cycles typically.
The sheet also mentions the lithium ion battery pack prefers partial discharges as opposed
to full discharges to lengthen, optimize and enhance the lithium ion battery packs longevity.
The lithium ion battery pack prefers to be discharged no more than 60% of total capacity:
4400maH times 0.60 equals 2,640maH. This would be equivalent to approzimately two and a quarter hours on medium(500lumens) illumination setting as a conservative estimate or alternatively one and three quarter hours on the highest illumination setting.
If one needed additional battery capacity requirements on the day of bicycle tour or ride as a battery backup or extension to battery reserve capacity; Geoman has spare/extra Lithium Ion battery packs for $40 per extra battery pack; also as well.
This is altogether, not a bad idea as in the colder upcoming autumn weather Lithium Ion battery pack capacity may be compromised by at least ten percent or more in total run time/capacity.
I will be taking the Magicshine P7 based lightset out on the local streets where I live with an outside temperature of about 48 degrees F here in New Jersey, running the lightset on the highest lumen P7 LED setting for about an hour or so in order to test the overall general lighting and beam width/depth/quality first impressions.
I will also use the helmet mounting option first as Geoman was so generous to have included it in the Magicshine lightset kit; so I figure I might as well test that also as well at the same time as testing the Magicshine Lightset overall.
Its was fairly easy and relatively self explanatory to use and mount the large two inch diameter black latex o-ring around the horn on the base of the LED Lightset and then thru the helmet mounting base and the other end of the o-ring around to the other side of the horn on the base of the LED Lightset to secure the Lightset engine securely.
The 3/16 of an inch thick black latex o-ring can best be fitted on the front horn best by first removing the small phillips head screw to facilitate the temporary removal of the black anodized aluminum base of the LED Lightset to initially set the black latex o-ring in its assigned channel due to the fact the front mounted lightset wire temporarily obstructs the path for securely inserting the black latex o-ring for its initial placement position in its channel/lip.
The utility of moving ones head is useful to custom aim/direct the Magicshine P7 Led Lightset where it is best illuminated and seen on the ground both in front of the bicycle as well as in the far off distance at high lumen intensity to evaluate the merits of overall general bicycle lighting and the desired beam width/depth/quality first impressions.
An additional added unintended potential benefit for both the touring and/or mountain bike cyclists might be the head mounted Magicshine P7 based Lightset Engine might better illuminate, reveal subsurface road obstructions and follow the irregular contours of the road better as well as reveal some of the more subtle shadows of road surface irregularities before inadvertently hitting them unintentionally; as a result of its higher vantage point helmet mounting position.
Furthermore an added unintentional potential consequential benefit of having the Magicshine P7 based Lightset Engine mounted on the helmet might also help to further stabilize and reduce the undesired vibratory artifactual visual illumination based bouncing/shaking effects of mounting the Magicshine P7 based Lightset Engine on the handlebars; for example while cycling on rough mountain trails, obstruction/roots strewn paths; one can dynamically aim ones head to light and illuminate the desired path ahead; well in advance.
Additionally, mountain/touring biking cyclists may also wish and/or desire getting a second Magicshine P7 based light engine also mounted on the helmet; to increase the depth, illumination and the desired characteristic led lightbeam width, shape and quality by aiming the two individual independent Magicshine Lightset Engines in combination together; one dedicated for close range illumination and the other for far away illumination; similar to benefits achieved using a double shot led lightset engine setup (i.e. cateye twinshot)
Moreover, having a second Magicshine P7 based light engine mounted on the helmet affords one additional adjustment and scalability options in the adjustment of the total lumens scalability value that can be selected by the user.
To help illustrate the point; reference column matrix below (reference column number by the bracket grouping):
First column ----->> First Led Lighthead(lumens) is streetside
Second column ----->>Second Led Lighthead(lumens) is curbside
Third column ------>>Total Led Combination Lighthead(lumens) current draw along with battery run times for 4.4aH pack
Fourth column ------>>Derated battery run times for 4.4aH pack
(Off) / (200lumens(low)) / (200lumens equals 440ma / ten hours )--> (six hours(derated))
(200lumens(low)) / (200lumens(low)) / (400lumens equals 880ma / five hours) --> (three hours(derated))
(Off) / (500lumens(medium)) / (500lumens equals 1,100ma / four hours) --> (two hours +24min.(der.))
(Off) / (666lumens(high)) / (666lumens equals 1,466ma / three hours) --> (one hour +48min.(der.))
(200lumens(low)) / (500lumens(medium)) / (700lumens equals 1,540ma/two hours +51min)-->(one hr.+43min(der.))
(200lumens(low)) / (666lumens(high)) / (866lumens equals 1,905ma/two hours +18min)-->(one hr.+23min(der.))
(500lumens(medium)) / (500lumens(medium)) / (1,000lumens equals 2,200ma / two hours) -->(one hr.+12min.(derated))
(500lumens(medium)) / (666lumens(high)) / (1,166lumens equals 2,565ma / one hour +43min)-->(one hr.+2min(der.))
(666lumens(high)) / (666lumens(high)) / (1,332lumens equals 2,930ma / one hour +30min)-->(54minutes(derated))
The matrix table above shows just some of the potential possible combination that would become available for selection based on your personal preferences or circumstances on the night of the bicycle ride/tour.
Remember Lithium Ion batteries should not be discharged more than 60 per cent of total rated capacity.
4,400maH times 0.60 equals 2,640maH working current so make sure to derate the above calculated run times by 40 per cent,
in order to ensure one can potentially obtain the typical 500 Lithium Ion battery pack discharge cycles.
Derated run times is displayed for your reference if needed in the right last column in the matrix table.
Unfortunately, at the 1,000lumens, 1,166lumens and 1,322lumens illumination light levels the battery run times are only around an hour; so if continuous run times at these high intensity lumen light levels are anticipated, one would need extra Lithium Ion Battery packs to extend total run times to whatever one would need.
An investment in a quality P7 based Lightset is an investment in confident, safe and enjoyable nightime cycling. With that being said I will go into some amplifying details on some firsthand impressions of the Magicshine P7 based Lightset.
I definitely will have to say that the Magicshine P7 based Lightset Engine Kit is a very complete and impressively well put together kit; for the under the sub $100 category P7 based Lightset Engine.
The minimal very compact footprint profile and total weight of the lightset engine is sufficiently small that one can easily put two Magicshine Lightsets on ones helmet at the same time; as the lighthead is only about 240grams in weight along with its similarly lightweight and minimal 200gram external Lithium Ion based battery pack that is easily tucked away in ones rear cycling jersey pocket.
The forty-five inch cord from the lighthead that goes to the external battery pack is sufficiently long so as to easily reach ones rear cycling jersey pocket conveniently.
The dime sized rubber covered green glowing switch on the back of the lighthead has a nice tactile feedback quality and feel to it. The build qualty of the lighthead itself is decidedly excellent and solid in both feel and looks; which is very easy on the eyes due to the sleek black anodized coating on the lighthead's surface.
I went for my first ride last night with the Magicshine P7 based Lightset mounted on my helmet with the supplied helmet mounting bracket from Geoman. The helmet mount has a nice and great lightset head tilting adjustment feature that makes it easy to vary the vertical tilt angle evenly and smoothly in a controlled manner using only one hand; even while riding ones bicycle.
Kudos and many thanks to the Geoman for doing his homework and getting this helmet mounting bracket for his loyal and faithful customer/users; as I am sure that they will fully enjoy its exceptional utility and safety options it potentially offers to Magicshine Lightset users/customers.
All of you reading this are probably wondering how did the Magicshine P7 based Lightset perform. My initial trial bike ride with the Magicshine Lightset with it mounted to my provided helmet mount was for about an hour and fifteen minutes with the Lightset set on the highest lumen intensity for the entire ride.
The lighthead's beam quality is absolutely superb and intensely white and bright in intensity; with just the right amount of evenly divided spotlight and accompanying healthy amounts of needed desired spillover floodlight just outside the spotlight's corona.
Now being a user of the Princeton Tec Switchback I LED Lightset which is now a rather dated LED lightset; I just was not prepared for the light intensity in the LED spotlight and floodlight quality arena.
In comparison to the Princeton Tec Switchback I Lightset this is a spotlight and floodlight monster; as this is another level of bicycle lighting illumination altogether and will dramatically alter your nighttime cycling experience(s) at multiple level(s).
I was able to ride on my bicycle anywhere from approximately ten miles per hour on the flats to up to approximately twenty-two miles per hour on mildly sloping downhills with total utter confidence, safety and ability to see everything in front of the bicycle on the dark pitch black roadway.
As a result, I was able to rapidly settle into and enjoy my nighttime bicycle ride instead of worrying about being seen and also worrying about seeing what is in front of my bicycle safely. During the ride, I felt I never had to worry about slowing down for safety reasons; trying to read the road subsurface at night for potential road obstruction hazards or dangers.
I will have to definitely say this is one powerful and intense updated P7 based LED torch Lightset put out by the folks over at Magicshine and can safely say I have never seen or experienced such a high quality level of bicycle lighting illumination before in a bicycle lighting system. Kudos to the Geoman and Magicshine people for a job well done; to successfully bringing this product to the bicycle lighting market.
I have no doubt they will have no trouble selling many more of these now updated P7 based LED Lightsets once the good word of mouth advertising and good press release communications news gets out about how good the level quality of currently updated P7 based LED bicycling lighting system design has gotten.
During the one hour and fifteen minute nighttime bicycle ride, the Magicshine Lightset was set on its highest intensity setting the whole time and the Lithium Ion external battery pack did a fabulous job at maintaining this high level of light intensity without missing a beat.
Even after seventy five minutes of high light intensity being delivered to the P7 based LED Lighthead, the level of light intensity remained high during the whole time without any signs of fading or diminishment in light intensity.
I plugged in the Lithium Ion external battery pack into its Lithium Ion based recharging AC adapter and it recharged the battery pack in about an hour without any muss or fuss about it; with the LED on the recharging AC adapter turning green after it finished showing it was finally done recharging the Lithium Ion battery pack.
The whole Magicshine MJ-808 LED Lightset Kit is a well put together and thought out bicycle lighting system upgraded and enhanced with the newer P7 based LED Lighting technology which is now starting to be widely available and starting to enter the bicycling lighting system market.
Everything about the Magicshine P7 based LED Lightset offering; from the LED lighthead mounting system; to the LED lighthead beam quality and the LED lighthead casings modern and updated sleek black anodized looks; to the advanced Lithium Ion based external battery pack subsystem design and its battery run time life is fantastic.
These are all potentially desirable invaluable bicycle lighting system characteristics and traits in purchasing a potential bicycle lighting system.
When I was contemplating purchasing this particular Magicshine bicycle lighting system I was initially concerned with all of the above discussed referenced items in this review. I can safely say after having experienced firsthand; the Magicshine P7 based LED Lighting Kit System will immensely add a much appreciated measured level of added bicycling safety and enjoyment to your next nighttime serendipitous bicycle riding road/mountain experience; at a fair value price that cannot be beat, to boot.
To the guys at Geoman/Magicshine; many Kudos/thanks for bringing this updated P7 based LED bicycle lighting system product successfully to cyclists worldwide via the internet; finally cyclists on a global wide basis have an alternative choice when it comes to selecting both a decent and very powerful P7 based LED Lighting System for their nighttime bicycle lighting system needs.
Thanks guys for reading.
