here, and get a charger from your local soul swallowing, small business wrecking super store, or just order one with your battery. you could get a bigger battery, incase you decide to add a second light or go for a higher watt bulb. I run a 35watt halogen on my setup and run a 10ah battery. weighs quite a bit, but it just adds to the workout. I also have a 20watt lamp on my bike, but I rarely run it. If I was riding on a mup at night, I would use the small one, but I prefer the 35 on the roads.
So, a 35watt halogen lamp is fine for roads? I just might opt for that instead of a 50watt.
sorry for my newbness, but I too am interested in building one of these contraptions for as cheap as I can. I love the challenge.
I saw this in a website for only $2.50. It's a 50w halogen spot MR-16, 12V narrow spot, bi-pin base.
Will this be bright enough?
If so, is it just a matter of putting this lamp into a housing and connecting it to a gel cell (sealed lead acid) battery
like these?
I'm very comfortable with soldering as I have tinkered with upgrading xboxes (lighting, etc).
Thanks!
BTW, what does the AH rating on those batteries mean? Is it the same as MAH on NiMH batteries?
