My OrcaTorch D630 V2.0 arrived recently. A big thanks to
@rob.mwpropane for getting me a deal on it!
It arrived in a nice case, similar to the one that accompanies the bigger DiveRite lights. The hard goodman handle seems to be well-designed and it actually feels more comfortable on my hand than the DiveRite goodman handle. Externally, the build quality seems quite good. The canister has a velcro "fold over" strap to attach to your harness. I know that some manufacturers overstate their output claims. I went out at night and did a side-by-side comparison with my DiveRite LX20 that is rated at 1500 lumens. I don't know if the Orcatorch is putting out 4000 lumens, but it is substantially brighter than the LX20! Without having batteries in the head, the OrcaTorch is a little lighter on my hand than the LX20. The weight of the LX20 doesn't really bother me, but it's still nice have less weight on your hand.
Note: The OrcaTorch is a can light with twice the battery capacity of the LX20, so I get this isn't an apples to apples comparison, but it's what I've got in other lights, so I was using it for comparison.
Finally, I did a burn test. I put the light head in a bucket of water and took a picture each hour on the same camera settings. By eye, or from the images, I didn't notice any dimming after an hour of run time. By the second hour, it did seem to have dimmed somewhat and it continued to taper off slowly after that. At the 4.5 hour mark, it was flashing red, indicating less than 10% battery. At that point, I did a side by side comparison again with a fresh LX20 (rated at 1500 lumens). The LX20 was brighter, but not by a huge amount. I'd estimate the OrcaTorch was still putting out something like 1000 lumens at the 4.5 hour mark. Now I'm just looking forward to getting it in the water!
