Last year I was disappointed by the 600L and thus I build my own copying Achesalot but using cheap drivers from dealexteme and use 7.2v li-ion 4000mah $25 battery from batteryspace.com . brighter then ARC and Trinewt by far. I have a lux light meter that I test all the light with. I wanted to see if this year light are brighter or not.
my previous last year build.

the helmet ones were 43 lux 4 led running 14.8v using kennon driver at 750ma and 32 lux 4 led running cheap $1.50 driver at 500ma.
with the new seca and 800L 400L out. I borrow them to do a lux meter test and beam shot review.
camera setting at 2" iso 400 F 8.0
light meter reading seca 700 at 41 lux( this is by far the best beam spread) problem is that seca ( enough though very light weight) sits 4 inch high on your helmet, so it's best for handlebar mount.
light meter reading 400L at 22 lux better then 22lux of trinewt( go figures) ARC at 21 lux.
light meter reading on 800L is 44 lux medium beam best for handlebar mount
light meter reading on the 800L and 400L combine is 65 lux almost as bright as TT 30w HID at 66lux.
Niterider flamethrower HID at 19lux
DIY 4led q5 750ma
DIY 4 led ssc 500ma
all diy 8 led together on helmet
