XINKAITE 100m Diving LED Torch, Cree XML L2 2000 Lumens Waterproof LED Flashlight(18650 Battery NOT included), One mode for Diving, Camping, Hiking, Climbing

What they don't tell you is that the switch is 4-position...click-low beam- click-high beam, click flashing, click-off...totally frustrating trying to use this thing. At the brightest setting it is very bright but you have to juggle the switch to get there...I wish they'd give the switch info before you buy it, I would pass on this and get a Mag-Lite.

Really bright, gets the job done. Dunno how waterproof it is, I don't use it for diving.
