Headlight for fast ebike any idea ?

[Ariane]

Hi Guys,

I currently have (4) magicshine 900 lumens on my ebike but the result of that beam didn't satisfy me, even if they are at the maximum. I like to know if someone here uses a motorcycle head light on his ebike with a low and high beam switch.

Thank you
Ariane

Not on my ebike, but on my motorbike, which is smaller, lighter, and slower than my Ebike. I have a Honda MB5 who's alternator can only handle 60 watts total, for lights, ignition, gauges, and battery recharging. They used a special 15 watt headlight that was too dim to really use, and not made any more. So I replaced the headlight with a conventional headlight that used an H4/9006 bulb. Then I bought a cheap eBay LED H4 bulb that draws 10 watts. It's a whole lot brighter than the Halogen H4 it replaced.

Thank Drunkskunk,

I have seen many option for motorcyle headlight on eBay seem very interesthing,

Good day!

this is what I am using x2 angle eyes with cree 2000 lumens and independent batterys

This is what Ive been using on all of my builds for a headlight and havent had one problem with any of them.

Yeah I think so to but if you had 2 of them you would always be able to see
(think spider) lmao

there are lots of light both for bike and motorbike lights on ailexpress the cree one are good last me about 5 year but audi electric bike uses el tape which can be cut too most shapes or names (as long as you have a joint too each letter) also on ailexpress and ebay hope this helps

Night car racing ,Audi electric bike and Tron motorbike all use EL Tape or EL wire

Hi Guys

Finally i bought (2) of these about 10 000 lumens each if it's true

That headlight offers a theoretical maximum of 2,880 lumens, pour votre info.

 

[MadRhino]

Bike lights were not satisfying. I now buy off road work lights

 

[litespeed]

Got a link for that light?

Just the first search result. I bought on Aliexpress, but have seen some locally in the automotive aftermarket accs.

 

[izeman]

those are nice https://www.aliexpress.com/snapshot/7338482628.html?orderId=72964558696831
and with some led driver modding those perform very nice as well, i modded the driver to output 20W, so every leds sees 3W, which should give a total output in the 3000lm range. https://www.aliexpress.com/item/SecurityIng-7-x-CREE-XM-L-T6-LED-Super-Bright-3200Lm-Bicycle-Flashlight/1756201327.html?spm=2114.13010608.0.113.upRJgo

those CAN'T BE 10,000lm. even IF they drive every single led with full 3A (what they don't because of heat issues) they can produce a maximum of 3.000lm. (3x 1.000lm).
i'd expect something around 1.000-1.5000 for the three-pack of them - which still may be enough for your needs.
ps: powered by USB, they can't have more then 10W (5V * 2A max), so it's 100% sure that they feed very led with not more than 3W, which results in max 400lm/led.
pps: i don't want to say that those lights are not useable, but HATE those chinese exagerations.

Hi Izeman,

Thank you have serious doubt about the lumens announced but a price, I can't resist to try (2) of them, good day!

sorry. didn't realize you already bought them have fun with it!

Lumens produced by the led itself has little to do with the depth and quality of the vision that you will have. This has more to do with lens, reflector and color spectrum.

If you look at the design of various automotive light fixtures and compare the vision produced by different lights that are using the same bulb, you will notice the importance of the shape and surface of reflectors and lenses. Color spectrum is also a major factor in how the the light travels through air that is loaded with fumes, water, dust, etc... That is why HG bulbs are so popular, for the color temperature that they produce. The way the light source it is mounted in different fixture design, makes the vision depth and quality varying a lot.

My belated 2c is i dont agree with much of this (in theory).

Fundamentally,

A/ yet another set of batteries sucks on an ebike &
B/ USB powered solutions are limited for the task at 5v. Cooling fins are not a good look for usb devices.

You are limited to ~1 amp or 5w on usb as i understand it. The lights are a long way from the battery, not good for 5v.

SO:

There seem many cheaper (no batteries, simple) lights on aliexpress etc. which happily run on anything between 12 and 80V ~.
e.g.

https://www.aliexpress.com/item/Motorcycle-Motorbike-Bike-LED-Headlight-Spot-Light-Head-Lamp-Front-Light-12V-24V-36V-48V-80V/32697702241.html?spm=2114.40010308.4.41.Z4UDTT

Plug them direct into the ebike battery. Simple, cheap and powerful. (I assume these auto ranging transformers are reasonably efficient.)

We are in an era where we can expect as good lighting as a motorist, given the efficiency of LEDs. A very different paradigm from very limited onboard power on traditional bicycles.

On ebikes we have some power now, but not to burn, but we can now have the best ledS have to offer.

If you adopt the logic, "u could do worse than copy what worked for cars", then 2 lights spaced seems sound. Dont reinvent the wheel. Borrow what the auto industry has learned about ideal aiming of beams etc.

Many would be happy to add a range preserving 10wh to their storage for good night lighting per hour, like a car.

dorky as they sound, i have considered an integrated (indicators/lights/boombox ) bolt on assemblage which is a poor mans fairing. Over 25kph, wind is the main resistance.

Hi Guys,

This device need 4 X18650 Cell as power pack and about 8 Amps to work, like i see on many other suppliers, good day!
