My wife bought me a Sola 600 Photo for Xmas in December 2010. It worked great for 3 years, but recently had some issues. When the charge lights wouldn't come on, I went online and read the very helpful L & M instructions for getting the light out of travel mode. When that didn't work, I called and a very nice CSR walked me through opening the light and unplugging and replugging the battery to reset the light. That worked and everything was cool for another few months. Eventually the charge signal started flashing red sequentially at high speed and the light wouldn't go on. I called up, exhausted all the remedies and then was told that since it was well out of warranty, I could send it in and they'd fix it for about $85.
I got the light back, charged it and tested it. It worked great. Last week I took it diving and oops, it flooded. I called up L & M and Jon said, "no problem, send it in and we'll take care of it of course." I returned the light to L & M with a request to please hurry, as I'm competing in the Monterey Shoot-Out this weekend and then Monday we're leaving for 10 days of diving in Alaska. One day later, I got a call from Jon, who said "We don't make the repair part for your old 600 anymore, so we're giving you a new one. I stopped in there and he handed me a nice brand new Sola 800. No Charge.
In my 61 years on this planet, I have never had better customer service. Ever.
You recommend here a torch that obviously causes lots of problems, just because the company has a good customer service? I would rather prefer a reliable torch. I am currently using the F.I.T. 2400 LED WSR as well as the UV version, and in my 30 years of diving I never had a better torch. Ever. :-)
Stronger light output, longer burn time, much broader flood than the Sola, 100% anodized aluminium, user exchangable battery (6 Ah Lithum 32650; spare battery = 15 Euro). WSR version has both flood AND spot, therfore you can use it as normal diving torch as well.
For WA, a warm colored flash is an advantage because you get a very nice blue water in the background (the auto white balance corrects the warm colors from the flash which leeds to cold blueish colors of the background). Hovever, I do not see a reason for a special flash color in macro photography, because you (or the camera in "auto" mode) can correct the color with the white balance setting.
