Does Color Matter for Fishing Lights and Dock Lights?
While green underwater lighting has surged in popularity, anglers used white light for decades before green alternatives hit the market. Today, green, white, and blue are the three primary options for dock and fishing lights, leading many to ask: which color actually works best?
Although any light source will attract marine life when projected above or submerged below the surface, specific environmental conditions make certain colors far more effective. Baitfish react differently based on water clarity, depth, and ambient light. If bait isn’t gathering around your current setup, changing your light color can kickstart activity—much like swapping out a lure on a slow day.
To give you maximum flexibility on the water, the AlumiGlo DockPro 4500-X3 Dock Light features a multi-color remote control, letting you instantly switch between Green, White, and Blue modes to adapt to changing conditions.

When selecting lighting for boats, docks, or piers, green and white are the most effective choices for drawing in marine life. Because both project high brightness underwater, they attract baitfish and game fish from greater distances.
-
White Light (Maximum Coverage & Speed): Containing all wavelengths across the visible spectrum, white light produces higher overall lumen output than any other color. If fish are in the vicinity, white light will draw them in faster than alternative options. The trade-offs? White light creates higher ambient glare for human eyes and tends to attract more flying insects above the surface.
-
Green Light (The Industry Standard): Green light strikes an ideal balance. It cuts through cloudy or murky water exceptionally well, creates an attractive glow beneath the surface, and draws significantly fewer insects than white light—making it our most popular option among anglers and dock owners.
-
Blue Light (Aesthetics & Ambience): While blue light offers slightly less underwater penetration than green, it produces a soothing, high-end visual appeal. Blue is primarily chosen for cosmetic enhancements, dock accenting, hull lighting, and architectural highlighting.
We are often asked how—and why—underwater lighting is so effective at attracting marine life. The mechanism is simple: light triggers a natural marine food chain that mirrors daily ecosystem behavior driven by sunlight, moonlight, or artificial light.
Submerged lighting draws in microscopic plankton. As plankton concentrates around the light source, small baitfish arrive to feed, which quickly draws larger game fish into the target zone. (Read more on How Fishing and Dock Lights Attract Fish.)
Green Light vs. White Light: Which Performs Better?
While light selection is crucial for both fishing and shrimping, green and white remain the two industry-standard choices. Although green is currently the most popular, experimenting with both can turn a slow night into a successful outing.
In controlled field tests comparing green versus white light in the same waters, we observed a distinct pattern:
-
Green Light consistently attracted a higher volume of smaller baitfish.
-
White Light attracted fewer total numbers, but noticeably larger baitfish.
Just as you would swap lure patterns based on conditions, switching light colors allows you to target specific marine activity.
To maximize your options on the water, our AlumiGlo SuperBrite X2 Dual-Color Fishing Light allows you to run Green light, White light, or BOTH simultaneously. For dedicated green-light enthusiasts, our high-output SuperBrite 4800-C Green LED Fishing Light has quickly become a premier choice for fishing, shrimping, and ice fishing.
Pro Tip for Success
The secret to pulling game fish under your light is generating a dense concentration of bait. We recommend cycling through Green, White, and Dual-Color modes for 20 to 30 minutes each to observe which spectrum produces the highest bait density on any given night.
