The underwater world is filled with a multitude of fish and creatures. Most of these animals, large and small, naturally display brilliant colors. However, as light travels through water, the colors get filtered out and everything becomes blue/gray.

When an artificial light is brought with a diver, the light travels a very short distance to the object and back to the diver's eye. This means that you can enjoy vivid natural colors wherever the light is pointed. Low visibility, low light and night diving all require artificial light sources in order to see the surrounding environment. Dive lights come in three main types of light output: Conventional (Xenon or Halogen), HID (High-Intensity Discharge) or LED (Light Emitting Diode).

The difference is the color or color temperature of the output. Conventional lights are a whiter light, burn hotter and use the most energy, HID are a bluer color light, use a ballast system and take a moment to come up to full brightness when turned on. LED are also a bluish light, but use diodes instead of filaments. They burn cooler use less energy and are the most durable.
