How many lumens per watt. And what is the candela per watt?
Looks similar to the Imalent HR20. I would like to see a weight size comparison. I bet in a head to head comparison, the HR20 xpl hi would still throw double-despite my concern that the xpl hi needs a 24mm smo to get a good 1 watt, 300ma, lux for good 2 meter inspection over an 8 hour day.... Also, on an edc style lamp, the dial the least output necessary (infinite dimmer) is absolutely essential for best runtime.... This thread didn't mention usb port. This class of lights need a charge port for casual top off and too darn tired evenings to fiddle with 18650 extraction, insertion, repeat to get into light. Also, ability to charge phone would add justification to wearing it on my belt.
