Bargain diving torch. Bought one to test and I was surprised at how good it is. It even comes with 3 spare o-rings. It has 2 x P50 LED. One is cool white and the other is warm white. The warm white is very nice. It is slightly warmer than my 2700K light. Simple operation with a very pronounced magnetic switch. One click for warm white, click again for cool white, third click turns off. Can be powered by 3 x AAA, 26650, 21700, 18650 battery. Comes with AAA adapter and 18650 adapter.
I have tested it in the swimming pool. Beam pattern is more of a flood then throw. While there is a hotspot it isn't well defined. Not sure what the reach is, but it illuminated the pool from end to end. Planning on taking it prawning. I don't need 100m reach while prawning, just need wide beam that can illuminate few meters.
Edit:
With my uncalibrated eyes I can say that thr torch does not output 2600lm of light. Closer to 1200lm. I left the torch on for 30 minutes and temperature didn't go over 41.8 degrees Celsius with ambient temperature 24 degrees Celsius. The output diminished in a linear manner. Definitely no buck or boost driver inside.
pretty bad reviews
No focal point so light is lost. Rubbish for diving
