Hi,
At this time, I only dove the chineese led light in dark & muddy lake. The time I dove at 71m, the water was particularly dark and loaded with particles.
Unfornatly, I won't be in a clear water before the end of septembre.
This light is cheap $58 and bright very well (1000 lumens). The cone of light is good. All my budy told me it was a good small torch.
There may be one objection: what about the electronic circuit along the time.
The SL4 costs +/- $100 and brights only at 250 lumens. I don't test it. I don't know anything about the cone of light.
The SL6 costs +/- $66 and brights only at 204 lumens. I don't test it. I don't know anything about the cone of light.
The D8 costs +/- $130. It is not a led light. It is a xenon light. uwkinetics annouce 30W. It is probably like the chineese 100 lumene one. I don't test it. I don't know anything about the cone of light.
You can also consider this light:
- ebay item 251076324857 (18650 batteries version) at $66
or
- ebay item 251066450706 (26650 batteries version) at $84.
They claim it is a 200m ligth that bright 1600lumen. I don't test it. I cann't tell you about the 1600lu (reality or ???) and the light cone.
Maybe one objection: what about the electronic circuit along the time
... but keep in mind if you can dive this light during one or 2 years, it is a good deal when you compare with buying wellknown brand light like metalsub, tillytec and other hartenberger
