LED’s Dive!
Underwater torch using Luxeon LEDs
It can often be fairly dark under water, especially at greater depths. A diving torch is essential if you want to be able to enjoy the marine scenery (or to help with a rescue operation). It’s easy to go out and buy a new lamp, but an old one still has its uses too! More so if we add some powerful LEDs.
