Well, I've been using my lighting system for about 8 or 9 months now.

I've got a 10watt/12volt lo-beam and a 20watt/12volt (energy efficient) hi-beam. I have a 1watt LED rear tail-light. I'm using a 5ah SLA.

By my calculations (please correct me if I'm wrong), my lo-beam can be used for 5.45 hours maximum and just under 3 hours without harming the battery. I can use my hi-beam for 2.85 hours maximum and 1.5 hours without harming the battery.

The entire light assembly attached by one zip tie (for the rear tail-light), removing velcro fasteners, a quick release buckle (for the battery), and one allen bolt (attaching the headlights to the bike). I can remove everything off the bike in just a couple of minutes and reattaching it is just as easy & fast.

I also use a red & white guppy headlight on my helmet and red/white/blue Tireflies on my valvestems.

I have been told that drivers have mistaken me for a police motorcycle in the mornings and that I'm easily visible from distance. Biking at night has been a total pleasure. Riding a recumbent, I can get a good look at the stars as I cruise around.

I will hopefully post some pics soon.
