-Very bright, I think the 510 lumen rating is true.
-Quality of the body is good, with well machined threads.
-Has o-rings in all the places, so it should be water resistant.
-The lens is glass, so it won`t scratch easily.
-It has a one of the best leds available now (XM-L) for a cheap price.
-The modes are useful and when you don`t want a lot of light low and medium are a good choice.
Only con I found is that the dropin has no contact with the body of the light making the dissipation poor.
This can be corrected putting alluminium foil around the dropin until it contacts with the body.
With that easy mod the light now spreads very even the heat.
Also if you don`t need the strobo and SOS mode this can be a con for you.
Checked with a multimeter as follows:
Cell at 3.98 volts
Low: 0.08 amps
Medium: 0.49 amps
High : 1.42 amps
Strobo: 0.61 amps
Sos: 0.41 amps
If you want a powerful light at a good price with one of the best leds available this is for you.
