Solus makes indestructible stuff. I made some dives with the backup and the beam is impressive. But (there is always a but...) solus is expensive.
I also tried the tristar. I was not impressed when i compared it with my 10 watt hid custom divers.
Green force germany(tillytec) plays in another division. Tried the led 500 cable light. My hid was washed out, no question.
Whiter light, focused beam that cuts in the dirty water. And fully compatible with the green force system.
They also brought the new led 1000 (osram ostar) 1000 lumen in a single led and it's focusable.

And last but not least, they have a backup light wich runs with 3 AA batteries. More powerful than the barbolight U-15 older version (4 leds luxeon III +/- 300 lumens). I compared it myself. I was impressed.
