I'm just thinking about buying some new lamps too, but maybe not these Xadventure's one.
For the moment I'm using RGBlue System 02 which are really good, great colors but I miss some power. The only nice test I could founded was for Keldan or Sola. I used Keldan lamps and I love the quality of the light, but I am also looking for lamps with several hours capacity for long rebreather diving.
Also, I'm using Keldan RED filters so I'm thinking to put blue fiters on my future lamps, and I remain perplexed about CRI expensive price when you add a blue filters on the front.
What about Bigblue 15000 lumens lamp? Someone did already compare these lamps with blue filters? They seems to have different color (warm and white) and still powerfull.
