All-night bike light & CatEye Mod.
I want to say hello and show report from my DIY project
Expectations : maximum weight : 300g minimum burn time : 10h lumens : max Parts list : - 1x Luxdrive BuckToot (when i'll get some samples from liear i'll try with Lux III or Xlamp 3w). - 4x 18650 cells 2,2 Ah & protection circuit (2x2=7,2 V 4,4 Ah) - 1,2w Xlamp 7090 – n2 bin , 58-60 lumens - L2 Optics 12 degree - seatpost or pipe & some alu plate - some old clamp from smart bikelight - switches, wires Efficiency - BuckToot at 7,49v takes 200mA from battery pack and gives 3,6v 350mA - it gives quite impressive value 88,54% CatEye HL-EL500 , compared to my DIY. Distance 2,2m, ISO200, time 1/8s, 2.8... And some modding works... second EL-200 was modded by led-s replacement some “30cd ultra bright” leds from *.HK led shop. . |
