UnderWater Kinetics has now upgraded their UK SL4 eLed modules to about three times the brightness with the same runtime. I contacted them and they did verify they made upgrades but would not elaborate. They must be using Cree or Seoul LED's now. The unit was rated at 38 lumens and is now rated at 116 lumens with a 10 to 12 hour burn time. Looks like they also upgraded the Q40 eLed as it is up from 42 lumens to 67 lumens.
So I wonder if new Rat's and PT's will be shipping with these new modules?
