4 mode means 4 output levels? What is approx lumens per different output levels?

How long can this run on high before one must turn it off, or down.

[dsche]

Gary123, levels are 45, 200, 800 and 3000mA so with U2 it 22, 90, 340 and 1010 lum

Time is varied from batt quality, with good 18650 (like Sanyo Panasonic etc) it must be about 40-50 min stabilized on high, than drop to lowest level

45mA is hi-frec PWM, others true regulated

Efficiency with this driver (it's custom produced too, not a cheap-garbage from DX) about 95%

Sanyo 2600mAh (measurement A and V from battery on high (3A on LED), temp from neck)

[dsche]

As you can see with good 2600mAh battery it's work 42 min with full stabilization (>1000 lum) than direct-drive to 2.9V (till 50 min no noticeable drop, but true full regulation 42 min only, here's no trick)

I think no one with 1x18650 can bite Krzysztof (this flashlight called 'Krzysztof II'). Efficiency on high about 95%
