When my LED Lenser frogman's packed up, I splashed out for some DiveRite CX2s. Admittedly, these are not cheap lights, but I figured that they ticked every box.
- Quality/ durable construction
- No twisty-bezel switch

- Switch that can be operated easily with cold hands and gloves while helmet mounted
- Range of power modes
- Good battery life
- Good reputation for reliability and after-sales support when things do go wrong
I've had them for about a year now and have been extremely pleased. They are very well made. Easy to operate. Easy to charge (internal USBC). Extremely bright on full power. Last forever on low power. Body shape allows them to be easily attached to a helmet with bungee; they can be taken off easily, but have never fallen off. The switch glows green when they have plenty of charge, then goes orange, then red as they get low.
Only downside other than the price is that they are quite bulky, so I invariably leave them off for caving to a sump and only put them on when I get in the water.
Pictured below new. They are less black and shiny now...
