Dive Torches have a place on every single dive, from looking at critters in a tiny crevice, signalling a team mate from across the wreck or lighting your next diving blockbuster there are torches for all users, price brackets and applications. Dive lights from Dive Perfect, Underwater Kinetics, Light and Motion and Apollo are ideal for recreational divers thanks to their quality light output, compactness and the fact that they run on typical household sized batteries such as AA or C cells.
Some of these dive lights are made to withstand the rigours of technical exploration diving, and feature immensely bright bulbs, a tight spot for signalling and large rechargeable NiMh batteries. The Dive Perfect Stubby LED-1000 makes an excellent backup light but is more than powerful enough for most recreational applications.
A light-emitting diode is an electronic light source. All early devices emitted low-intensity red light, but modern LEDs are available across the visible, ultraviolet and infra red wavelengths, with very high brightness. The LED is usually small in area (less than 1 mm2) with integrated optical components to shape its radiation pattern and assist in reflection. LEDs present many advantages over traditional light sources including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching. However, they are relatively expensive and require more precise current and heat management than traditional light sources.
