HI,
I am signed up for a 24 hour bike race later this summer and will need some lights, I will need 500-900 lumens for an hour at a time, probably 4 times.
Fancy bike light systems with rechargeable lights go any where from $200 to $1000. I do not need rechargable, as this will probably be the only race like this I will do. Its probably cheaper to build 5 throw away battery packs (maybe not?) was thinking of linking 8 alkaline d cell batteries together for a 12v power source to a 50w halogen bulb but that would probably not give me the lumens or burn time I am looking for so was wondeirng if any of you can suggest specs for a DIY project with LED or HID or even halogen bulb. Ideally, I will mount the battery pack into a water bottle cage mounted on the bike, bottle cage could accomoodate something the size of 2 soda cans or a 20 oz plastic bottle, thoughts, ideas suggestions?thanks
