Color and Underwater Lighting

Color for underwater lighting is used only for preference of the property owner. Green does not attract fish more than amber or any other color in the rainbow. We have done extensive research with different color bulbs underwater and color other than the user preference from a fishing standpoint is a myth. Unless the bulb has dye in the arc tube that creates the color the controlling factor of the color is the color temperature of the bulb. 

Think of it this way: 3000K Yellow-5000K Pure White-6000K Crystal White- 8000K Light Blue The higher the Degrees Kelvin, the whiter the color temperature.

Some underwater lights use a lower color temperature when put underwater appear to be green. Other underwater lights use a much higher color temperature that appear to be amber or yellowish depending on the amount of silt in the waterway. The green looks pretty to the human eye the yellow may not. The truth is if you put a scuba mask on and went under water in front of them they are both big bright white lights.

This is what the fish see. Color is a by product of the bulb type, temperature and the amount of silt and particles in the water. After testing many different bulb temperatures our research has demonstrated the brighter the light is the more bait it holds and the more fish it will hold for a longer period of time.
