Underwater Fishing Lights: Can RGB Lighting Work for Different Fish?
Updated: 6 days ago
Underwater fishing lights are not new.
Anglers have used green, blue, white, and other underwater lights for years around docks, boats, kayaks, and fishing areas.
But one question still does not have a simple answer:
Is There One Underwater Fishing Light Color That Works Best for Every Fish Species and Every Body of Water?
Probably not.
Fish can respond differently to different wavelengths of light. Brightness matters. Water clarity matters. Depth matters. Species matters. In some situations, artificial light may concentrate aquatic organisms around an illuminated area. In others, it may cause avoidance.
That is why we believe the next generation of underwater fishing lights should not be built around one fixed color.
With GLOW270, we are exploring a different approach.
Why Underwater Fishing Lights Need More Than One Color
Many traditional fishing lights make one important decision for the angler before the product ever enters the water:
the color.
Green.
Blue.
White.
Once you choose that light, you are generally committed to that color.
GLOW270 works differently.
Because GLOW270 uses app-controlled RGB lighting, anglers can change colors without changing the physical lighting system.
You can move between:
Green → Cyan → Blue → White → Red
and also adjust brightness.
That turns the same lighting hardware into something more flexible:
A Color-Selectable Fishing Light Testing Platform
Instead of asking only:
“What is the best fishing-light color?”
we think the more useful question is:
Which Color Works Best for Your Fish, Your Water, and Your Conditions?
That is the question we want to explore together with anglers.
Why Light Color Matters Underwater
Different wavelengths of visible light behave differently once they enter the water.
Red wavelengths are generally absorbed relatively quickly, while blue and green wavelengths can travel farther through many aquatic environments.
But there is no single rule that applies equally to every lake, river, reservoir, bay, or coastal environment.
Water clarity changes light transmission.
Suspended sediment changes it.
Algae changes it.
Depth changes it.
And fish species themselves may respond differently to different wavelengths.
That means the underwater environment is affected by two things at once:
how the light travels through the water
and
how aquatic organisms respond to that light.
Both matter.
Different Fish May Respond to Different Colors
Research involving multiple fish species has found measurable behavioral differences under different colors of artificial light.
Blue and green wavelengths frequently produce strong responses in aquatic studies, but that does not mean they are always the best colors for every species.
Some species have shown stronger responses to other wavelengths under specific experimental conditions.
That is exactly why we do not want to build a fishing system around the claim:
“Green is always best.”
The more useful conclusion is:
Different fish may respond differently.
And the answer may change again when the water conditions change.
Brightness Matters Too
Color is only one part of the equation.
Light intensity can also change fish behavior.
A color that appears interesting at a moderate brightness may produce a different response at a much higher output.
Artificial light also does not always create attraction.
Avoidance behavior has been observed in fish and other aquatic organisms under certain artificial-light conditions.
So a more powerful light is not automatically a more effective fishing light.
A useful way to think about the problem is:
Species + Color + Brightness + Water Conditions = Observed Response
That is the idea behind our testing.
Why RGB Control Matters for Underwater Fishing Lights
For recreational paddling, RGB lighting is often considered a visual feature.
Choose a color.
Change the atmosphere.
Change the look of the water.
For fishing, RGB control may serve a completely different purpose:
comparison.
With GLOW270, the same underwater lighting system can test several colors during the same trip.
The vessel stays the same.
The installation stays the same.
The location can stay the same.
Only the lighting condition changes.
Then brightness can be changed as a second variable.
That makes it easier to compare observations without replacing the physical light.
Instead of buying a green fishing light and later wondering whether blue or cyan might work differently, the angler can test those conditions from the same system.
That is why we see GLOW270 as more than another fixed-color underwater fishing light.
We see the potential for a color-selectable fishing light testing platform.
Want to see the system we’re using for these tests?
A Bass Lake Is Not the Same as Coastal Water
Fishing environments vary enormously.
A largemouth bass angler on a freshwater reservoir is dealing with very different conditions from an angler targeting redfish along the coast.
Crappie are different from catfish.
Baitfish are different from predators.
Freshwater is different from brackish water.
Clear water is different from stained water.
Even the same lake may behave differently after heavy rain, during an algae bloom, or as seasonal temperatures change.
That is why the better question is not simply:
“What color works best?”
It is:
What works here, for this species, under these conditions?
GLOW270 as an Experimental Underwater Fishing Light Platform
GLOW270 began as a removable RGB underwater ambient lighting system for small recreational vessels.
But as we began talking with kayak anglers and fishing communities, another possibility became increasingly clear.
Could the same RGB platform become the foundation for a more specialized fishing-light system?
We believe it can.
But a fishing version should not simply be the recreational product with the word Fishing added to the package.
Fishing creates its own requirements.
A fishing-focused lighting system needs to consider:
kayak and small-vessel hull shapes
protection from bottom abrasion
side-mounted lighting positions
fishing-line management
pedal drives
rudders
transducers
trolling motors
rod storage
electronics
RGB color control
brightness control
real-world fishing conditions
Most importantly:
It needs real-world field testing.
Why Side-Mounted Lighting Makes Sense for Fishing Kayaks
Fishing kayaks regularly encounter ramps, gravel, sand, rocks, shallow water, and other surfaces that can scrape the bottom of the hull.
For that reason, the center-bottom mounting strategy that works well for many paddleboards is not always the best choice for kayaks.
For kayak applications, we recommend exploring installation along both sides of the hull, near or slightly below the normal operating waterline where the specific hull design allows.
This approach helps keep the lighting away from the most abrasion-prone portion of the kayak while placing the light directly into the surrounding water.
For fishing applications, that creates an especially useful combination:
Protected Side Mounting + App-Controlled RGB Lighting
The mounting strategy adapts to the vessel.
The RGB system adapts to the experiment.
Together, they provide the foundation for a more specialized GLOW270 fishing platform.
What Should Anglers Record?
We want GLOW270 field testing to remain simple enough to use during real fishing trips.
A useful fishing-light record could include:
Target species: bass, crappie, catfish, redfish, baitfish, or other
Light color: green, cyan, blue, white, red, or custom RGB
Brightness: low, medium, high, or app setting
Water type: freshwater, brackish, or saltwater
Water clarity: clear, stained, or muddy
Approximate depth
Time and moon conditions
Result: fish caught, baitfish activity, target-fish movement, avoidance, no obvious response, or anything unusual
That is enough.
The goal is not to turn every angler into a scientist.
The goal is to make each field observation more useful.
From Fishing Stories to Fishing Data
Fishing communities already contain enormous amounts of practical knowledge.
But much of that knowledge is shared as isolated comments:
“Green worked great last night.”
or:
“Blue seems better where I fish.”
Those observations become much more valuable when we also know:
where it happened, when it happened, what species were present, what color was used, what brightness was used, and what the water conditions were.
One fishing trip does not prove that one color works for one species.
But consistent records from many anglers can begin to show patterns.
Imagine GLOW270 field records from:
North Carolina reservoirs.
Florida coastal waters.
Texas lakes.
Louisiana marshes.
California fisheries.
Clear mountain lakes.
Stained southern reservoirs.
Freshwater.
Brackish water.
Saltwater.
Every record adds another piece to the picture.
We Are Testing — And We Need Anglers to Help Us
There are many things we can test ourselves.
Waterproofing.
Mounting durability.
App control.
Electrical performance.
Brightness.
Color output.
But we cannot recreate every fishing environment.
That is where anglers become essential.
People who know their local water.
People who know the species they target.
People who notice what happens before and after an underwater light is switched on.
We are not asking anglers simply to endorse GLOW270.
We want them to help us learn.
And we want those experiences to become useful to other anglers.
Help Us Build the GLOW270 Fishing Guide
Our goal is to build a shared GLOW270 Fishing Guide using real fishing records from the community.
The idea is simple.
Record:
when you fished
where you fished
what color you used
what brightness you used
what species you were targeting
what you caught or observed
Every angler’s record can become part of another angler’s GLOW270 usage guide.
Maybe one angler finds useful results with green while targeting crappie on a particular reservoir.
Another may observe more baitfish activity under cyan in clear coastal water.
Someone else may find that lower brightness produces more activity than full power.
And another angler may test several colors and see no meaningful difference.
All of those results matter.
The purpose is not to create a marketing claim.
The purpose is to build a practical fishing reference based on real-world use.
Your Fishing Record Could Become Another Angler’s Starting Point
Over time, we want the GLOW270 Fishing Guide to organize observations around:
Time + Location + Species + Water Conditions + Color + Brightness + Results
A new GLOW270 user should not always have to begin from zero.
They should be able to learn from anglers who have already tested similar conditions.
Your fishing trip today may become someone else’s starting point tomorrow.
We Are Testing. We Are Learning. And We Need Anglers to Help Us.
We have the RGB lighting platform.
We have app-controlled colors.
We have adjustable brightness.
We are developing fishing-specific configurations.
Now we need the experience of anglers on real water.
Which Color Works Best for Your Fish, Your Water, and Your Conditions?

Test it. Record it. Share it. Help us write the GLOW270 Fishing Guide together.
Safety + Lighting: Our Next Development Goal
GLOW270 is currently an underwater ambient lighting system, not a navigation light.
It does not replace navigation lights, signaling devices, or other safety equipment required by applicable laws and regulations.
But we do not want our product development to stop there.
Our goal is to develop a complete GLOW270 Safety + Lighting Package that combines underwater ambient lighting with the navigation-light functions required for applicable small-vessel use.
The idea is simple:
One Lighting Package Instead of Two Separate Systems
Today, a paddler or angler may need to purchase an underwater lighting system for ambient illumination and then purchase a separate navigation-light system to meet applicable vessel-lighting requirements.
Our development goal is to bring those functions together.
We want users to be able to purchase one integrated package that provides:
GLOW270 underwater ambient lighting
vessel visibility lighting
applicable navigation-light functions
a more coordinated installation
one complete lighting solution for nighttime use
The final configuration is still under development and testing, and the exact requirements will depend on vessel type and applicable laws and regulations.
But the direction is clear:
Ambient Lighting + Required Navigation Lighting + One Integrated System
Our goal is to make nighttime vessel lighting simpler, more complete, and easier to purchase—without requiring users to assemble separate underwater and navigation-light systems themselves.
