Green Light vs. White Light
When testing green light vs. white light (clear), we found that the green light attracts more smaller baitfish, while the white light attracts larger baitfish in the same water! Changing colors of lights isn't any different than changing colors of lures when fishing different conditions.
In other words, they will both bring fish over to your dock! The green light makes the water column a little murky to see through. The white (clear) light shows the fish and other creatures better in our opinion. The true colors of all the different fish show up much nicer, the bottom is lit up better, and the illumination stretches out further.
The blue light is used to create a magical glowing effect in the water! It turns the water into a "dreamy" blue tint which will also illuminate fish and other creatures in the water. This color is used frequently in commercial applications such as boardwalks outside of restaurants and hotels.
