Bicycle lights

[Al_Havemann]

Can anyone point me in the direction of a circuit diagram to use a Lexon star (5 watt version) in a bicycle light with either a 6 or 12 volt, 4 amp/hr battery pack.

I currently have both 12 and 6 volt lights (a nightsun with a Nicad pack and another, noname light that takes 4 D size alkalines). Both lights have 15 watt halogen bulbs that I would like to replace with a 5 watt Lexon star and not being very knowledgable in electronics I don't know how to setup the circuit.

Thanks in advance for any help.

15 watt halogen bulbs are quite bright, wonder why do you want to change over to 5 watt LS instead? Is it because you don't need the brightness sometimes and just wants the run time?

Maybe to be more efficient? more reliable?
I think you should go with fluorescent lights instead as they are several times more efficient than LEDs.

LED's were MEANT for bikes. Hot, cold, jarring bumps on rocks and potholes. Filaments break and the fluorescents have no throwin power.
Mark my words: LED's will soon rule the world of bike headlights. LED's are already used extensively in tail lights and marker lightss.---Marc

My money will be on that the price of bright LEDs going up and up.

I figure they'll be like computers. The bleeding edge will always be expensive, but the tried and true technology will sell at a reasonable discount.

There's no free lunch though. You've gotta pay for better product!

Arc AAA?

The bottom line here is that early adopters always get reamed. Such is my life.
