Race proven! I put the light to the ultimate test by competing in the Gold Rush 24-hour Adventure endurance race in the Sierra Nevada mountains of California. Many of the other competitors had $500 HID lamps from NiteRider, Light & Motion, etc, yet throughout the race nearly everyone that saw my light commented as to its extreme brightness or asked where they could get one. It was that much brighter than anything else.
brightness: 500+ lumens / 7 million+ mcd @ 15 degree
weight: 120 gram headlamp + 60 gram electronics + 280 gram battery pack = 460 gram total
cost: $60 including batteries
lifetime: 3, 6, 12, 24 hours (4 brightness settings)
size: headlamp portion 5cm x 5cm x 2.5cm
rechargeable: Ni-MH or Lithium-Ion batteries (your choice)
unbreakable: LED technology
- Cyan (or Green) high power/high efficiency LED's
- high-transmittance TIR lenses
- high-efficiency DC/DC step-down converter
None of this was possible just a couple years ago, but now it can be done easily with inexpensive components you assemble yourself!
i've got several other power-LED instructables too, check those out for other notes & ideas.
