Newly Enlightened
I gathered three LSH-P's, two LSHF-P's, and my new Arc4+, and did relative lux measurements with LM631 meter. I used the same battery on each one, keeping the light on only for about 10 seconds, so the readings should be accurate for comparison. NOTE: these were not taken at 1 meter, but closer (but all at exactly the same distance), so these are not objective lux measurements, but only measure the lights relative to each other.
# 1853 LSHP 750 lux
# 881 LSHP 870 lux
# 1181 LSHP 1048 lux
# 1464 LSHF-P 1029 lux
# 1577 LSHF-P 1055 lux
Level 4 Arc4+ 1045 lux
Level 3 Arc4+ 1269 lux
Level 1 Arc4+ 1963 lux
Surefire L4 1380 lux
I guess I forgot to do level 2--too late now.
If Peter can do this with a 1 watt Luxeon on one cell, the possibilities for the Arc5 are awesome!
