We are getting more info on these new Euphos named underwater video lights that are rated at 2500 lumens at full power, which at that setting they have a 75 minute burn time.

The most interesting feature is the batteries need not be removed to charge them. I am not sure that is always good, as one might want to charge spares and swap them, but it also might be a nice feature, and it does have a remaining battery charge indicator.
