I've got a Sola 600, the version with only one setting for Red. Just got it wet for the first time on the Belize Aggressor III about a month ago (can't believe it's been that long ago already...)
Used it with my new e-pl1 setup and LOVE it, both the new rig and the light.
I was the envy of the boat with the Sola 600. That red light feature is fantastic. If you've done night diving with Tarpon around you know how they love to follow you and attack the poor varmints in your white light beam from over your shoulder, generally scaring the hell out of you in the process. Using the red light, I had no such issues. It did still spook some critters but others were totally unaware of it or me. Squid, octopus and crustations most notably were unaware. At 600 lumens white light it's bright enough to help fill in spots for aiding the flash and for video during the day. For night dives in clear water 600 is FAR too much. The red light is perfect and I don't see any need to have that adjustable. Was fine and when using a strobe you can't tell in stills that the red light is on at all. I used red light exclusively and a separate 600 lumen hand held light with tight beam pattern but big spill area for long reach critter spotting.
The one dive that I forgot to pop the damn flash before I dropped in (which means no f'ing strobe... :furious: ) I tried to use the Sola instead for stills without much luck. It helps fill in when used with a strobe but I think you'd need more to do anything other than macro where you're lighting a very small area very close to your housing.
