Vision X XIL-S1100 Solstice 2" Square Euro Beam Solo LED Pod Light
Input voltage 9 - 60 volt DC
50,000 hour life span
Low amp draw 0.75A
IP-68 rated housing
Equivalent light output of standard headlight
This one is a 2" square aluminum light that takes up to 60 volts of input. Cost is $120 but it puts out 800 lumens which should be enough for a 36V ebike. Good luck!
First post on the forums, some great reading here ïÂÅ
Thanks for the lead EVNewbie, I ordered the Solstice S1102 (15° beam) and fitted to my ‘Greenewheels’ (wisper 905 equiv) e-bike, and it works a TREAT.
I’ve got a 36V 13Ah battery on board, (42V full charge, 34.5V discharged), wired this up to the standard headlight wiring in the loom, which is pretty thin wire actually.
In any case this 10W LED is so bright, it looks as good as my car’s twin 55W halogens. Going into winter here in Sydney Australia, this has transformed my commute home. Was previously using a 1W LED and 5 W incandescent that came with the bike. Can ride a full speed down the hills on the way home now being able to see every last detail on the surface, so much safer.
Says on the package 900 lumens, 9 to 50V operating range, 0.75A at 12V, 50,000hrs, equiv to 100W halogen.
Measured current draw at 42V, was 240mA, so must have a good voltage converter inside as still 10W consumption at higher voltages. Voltage drop 0.2V at 42V so standard thin wire in loom on this bike is sufficient as that is only a loss of approx 50mW.
Not cheap but worth the money in my book, was looking to wire up three MR11 halogens in series and find a suitable enclosure for them, but this is much more elegant and efficient. Just have to turn it off or point it way down when passing other cyclists at night on the bike paths over the bridges I cross on the way home as they were obviously having trouble with the intensity.
The S1102 15° beam is the one to go for from what I can find out, 35° flood would blind other cyclists even if pointed down, plus be a waste of light to the sides, and the 10° is a bit too narrow I am told by the guy who sold it to me in Australia, he reckons somehow the (newer) 15° S1102 model seems to be brighter in the main beam in any case when compared to the 10°.
Not sure about the P7 themal protection thing is you refer to lifepo4ever?? In any case, some sites suggest 9 to 60V for this lamp, others 9 to 50V, the package says 50V max, so maybe this is not an option for 60Volters.
