Getting dark early on the East coast. BIG LIGHT ideas. I have a 68v 225w projector bulb that burns nicely in a fixed housing. Will I drain my 48volt 12amp hr battery in seconds or minutes? Should I remove it and not even go that way? It is bright. It lights up a 4 lane road.
 
I believe the police would pull you over and write you a ticket for blinding low flying aircraft
 
That light will draw 3.3amps per hour at 68 volts.So about 3 amps or so at 50 volts.It may not put up with vibration well.

50 watt LED, puts out 3,000 lumens! 12 - 13 volts, draws less than 4 amps. MEGA BRIGHT!

At night I have no issues with light.
Got a kick butt LED taillight too, in a motorcycle tail light housing, of course. LOL
 
See what a 50 watt LED does? Watch this video, convinced me, and gladly so...

A better example of the 50w LED

Attach that to your helmet. Make sure it's angle towards the ground, otherwise you will blind the drivers, which is not safe.
 
Im thinking your talking to me, since my bike is the only one you can see all of. LOL

The fork is from Bike Buyers, http://www.bikebuyers.com/PART-FY-TPT-570.htm Rigid but strong, double down cause Im a fat ass and I wont ride a fast bike without double down forks, suspension or not. The same site has a ultra sweet deal on double down (downhill style) suspension for for 1 1/8" steertube. My beach cruiser only has 1".
The mount for the headlight was an old ink cap holder for tattooing. You will have to come up with some ingenuity to mount the light bucket, I have that welded on, it left nice clearence for the neck and centered the light mount nicely. Lucky i guesse.

THe bucket from eBay, "bucket" is the "biker" term, its a shell http://cgi.ebay.com/ebaymotors/Harl...1956547QQptZMotorcyclesQ5fPartsQ5fAccessories from Bates.

The H4 headlight is a basic 5 3/4" h4 conversion. I squared out the hole, cut the sides and folded them over to created a mounting tab where the holding wires would sit over the tab, and put it together as you see. I already had a 12v dc/dc for my relay system, I just tapped into that for power. My lights use so little power I dont stress running them in the day too. Nice for safety and at the low draw they are almost invisible to the batteries.

The LED I got from ebay too http://cgi.ebay.com/50W-White-3500-.../170533205480?pt=Lamps_US&hash=item27b49235e8 I got a 100w one to make a custom flashlight with my spare A123 M1 cells! LOL 6000 lumins!

Anything else dont hesitate to ask, glad to help.

What will you be using for cooling/heatsinks.

I was going to use a liquid cooling system from "coolit", but since I have a full spare SMD and getting a cooler or heatsink in there was not looking feasable, I tried it with NONE! I have well well over 120 hours on it with NO ISSUES! Woulda had more but was outa town for month and a half! But the way its mounted uses no glues or plastic components, after hours of use the bucket is cool to the bare hand touch. I was worried it wouldnt last, its been so long now, I dont think its going to have a problem. I set it up for temp use ......... havent had a need to change.

Go figure!

Awesome to see you SilverSurfer! :) I hope everything in life is kick-ass. :)

The cooler you can keep that die in the LED, the brighter and more efficient it becomes, and the amount of hours it will burn for goes up in a huge way.

Even cutting a little section of a CPU heatsink from a scrap computer and getting it glued to the back side will be a huge helper.

Thanks Bro! Life is very good indeed! I do have a huge heat sink I can cut to fit in there, but there is not air flow in there either. Still, I will fit one too it just because I love the way it works so much I might as well improve it.
On my old route home there was an underpass I went under at night that was the darkest part of the trip, No lighting at all and being and underpass the lighting for the over route is in total shade. It it inky black under there! I stopped and could not only clearly see all the road in front of me and on both sides, I could see the WHOLE AREA! Even the details of the overpass construction, if there was anyone hiding anywhere they woulda been seen! I wouldnt hesitate to take it off roading, well, i would try to get it up to 14 or 15 volts off roading, but I hate crashing! Off roading at night is psycho! AZIZ! LIGHTS! LOL

Of course I didnt mean to take The Rapture off road, I meant putting the light on a FS MTB. Duh! [:eek:)
 
Any idea of the manufacturer of that LED chip? The ebay listing gives no clues..... Looks interesting as an alternative to multiple Cree MCE's or Luminus CBM-360/CSM-360's

I have the 50w and the 100w and neither of them have the slightest mark of any kind other than +/- for polarity.

Go figure?

The 50w is incredible, Im building a super flashlight with the 100w! I will post a thread, should be wild!
 
Cool. It would be interesting to see beam shots with these LED chips and your reflectors. Most of the challenge is getting a nice beam profile rather than alot of lumens.
 
If you ever see that LED turn to an(angry purple) color you're getting it to hot and the end is near.
