Hi, found your community on the search. I am using homemade 20w halogen bike lights and would like to replace them with LED's to increase run time. I usually use one 20w, sometimes two at once. My battery is a 14.4 LiIon so I am overvolting the lights. Two lights at once puts out quite a bit of light so I am spoiled. What kind of LED arrangement would get me an equivalent light output? And one more question has anybody experience with electric skateboards? I want to buy one good and found in the Republic of Skaters but can't choose.

Very hard to convert Watts (power, or energy used per second) to lumens (brightness) due to the fact halogens make more heat, so therefore typically use about 4 times the energy to give the same brightness. Your 40 W system could be giving you 500 to 700 lumens (total guess), and with LEDs you could get that and only draw maybe 10 W. If you are using a 14.4 Volt power supply, the current draw would be 2.8 Amps with your dual beam set up. That's a lot. Running 10 W of LEDs (you could have more than one with this much power) you would only draw 0.7 Amps. Still a fair bit for a bike light, and heat management is still needed.

I used to make my own bike lights with various incandescent bulbs, but for LED, I like commercial units. The circuitry to provide safe thermal management and charging, and various power levels, waterproof casings, etc. are all so good now on modern bike lights.

Here is a locally made (for us, in our provence) light I just ordered for example. It uses a 3.7 V Li-ion and still delivers 800 lumens.

Not sure if I'm making sense, but I guess the short story is: LEDs give us better bike lights.

Cheers,
