I am so full of Great ideas from this !!

http://tesladownunder.com/WorldsBrightestBike.htm#BikeLights

I ride a bike to work.
I ride a bike home at night on an unlit country road.
I use a 5 watt LED bike light which gives a feeble spot of light ahead of my bike.
So, I think to myself "what if I had a brighter light on my bike"
I think to myself "what if I had a really, really bright light on my bike"
Hey, I'm Tesladownunder, "what if I had the world's brightest light on my bike"
What would it take?
I have experience with a huge 100W LED that is brighter than a cars headlights.
But that is simple to do and I have already done that almost as a joke.
But what extreme can I take this to?
Lets make a real project of this and give it a real budget - say $5000.
So....here it is, ladies and gentlemen; welcome to the Worlds Brightest Bike Lights.
How bright? 100,000 lumens. Remember that figure.

and here is a starting point at 8000 Lumens!

Has anyone suggested seeking help for this? If not, may I be the first?

Looks like a fun time though...I can't wait to see what you come up with.

I see this not ending well when he blinds a car and gets run over.

Many Times

It was CP who showed this to me !

I'd like to see that one on strobe.

Damn 8000 lumen led emitter. That's some juice, and some heat.

Heh...looks like we'll be putting out bike-light fires on splatolite v2...

'course there's one other problem to solve:

Power:
3 x 12 V deep cycle 33 AH batteries
Run time:
est. 10 mins at 60 A 33 V

First he melted his helmet. Now he's going to melt his head. Good times.

If he travels at nearly the speed of light, will his increase in mass: increase the capacity of those batteries?

Wow that chip from DX looks interesting. Going to have to score one and a decent driver. I haven't done and LED project in a while.

All it takes is one inadvertantly placed mirror to make you look like beef jerky.

Better run a diffuser... I bet that thing has a hell of a washout area. I tend to like the dispersion pattern of the lamps with multiple lower powered LEDS than I of the single large emitter lamps.

If the sun ever comes out here again. I will try my best to utilize it....

so its really no that hard to make your own bike light huh?

The thing to watch with LEDs is you have to watch your current in addition to the voltage. Regular bulbs are resistors, all you have to watch is voltage. LEDs will take whatever current is available, be overdriven, and die fast.
