Soft-plastic colors are about more than just the base color of the bait.
Anglers will often see terms like Glow, UV, UV Glow, and Flake used to describe fishing soft plastics. They can all affect how a bait looks underwater, but they do not work the same way.
The easiest way to separate them is:
Glow — absorbs energy from a light source and continues emitting visible light after the charging source is removed.
UV — UV-reactive or UV-reflective additives interact with ultraviolet light and can change how the plastic appears when UV light is present.
Flake — small reflective particles in the plastic reflect available light as the bait moves.
A soft plastic can also combine more than one of these features.
Understanding the difference makes it easier to choose a plastic based on the presentation and conditions rather than treating Glow, UV, and Flake as interchangeable terms.
What Is a Glow Soft Plastic?
A glow soft plastic contains material that absorbs energy from a light source and then releases some of that energy as visible light.
Think of it as charging the bait.
Expose the glow material to a bright light or UV flashlight and it stores energy. After the charging source is removed, the material continues emitting visible light for a period of time.
That glow gradually fades and can be recharged.
This continued afterglow is what separates glow material from something that simply reflects available light.
In technical terms, the delayed emission associated with glow material is phosphorescence. Fluorescence behaves differently because it occurs while the material is being excited and fades very quickly once that source is removed.
For fishing, the practical distinction is simple:
Charge a glow soft plastic, and it can continue glowing after the charging light is removed.
How Do You Charge a Glow Soft Plastic?
Glow soft plastics need to be exposed to light before they can glow at full strength.
A bright flashlight can charge glow material, while many anglers use a UV flashlight because it can quickly energize common glow pigments.
Hold the light close to the plastic for several seconds before dropping it back into the water.
As the glow fades, recharge it.
Glow brightness and duration can vary depending on the material, color, charging source, and how long the bait was charged.
What Does UV Mean in a Soft Plastic?
UV refers to how certain materials interact with ultraviolet light.
FishDaddy uses reflective UV additives in a number of its soft plastics. Current FishDaddy product pages for Boller, Lucky J-Shad, Spike J-Shad, Spyro Tail, Quad Tail, and Double-Eye all describe UV-related visual properties alongside glow.
UV and Glow are not the same thing.
Glow material stores energy and continues emitting visible light afterward.
UV-reactive or UV-reflective additives interact with ultraviolet wavelengths while that light is present.
For anglers, UV should be treated as another visual characteristic of the soft plastic rather than as a guarantee that one bait will always outperform another.
Can a Soft Plastic Be Both Glow and UV?
Yes.
A soft plastic can have Glow and UV characteristics at the same time.
That is exactly why FishDaddy uses the term Glow + UV across several soft-plastic products.
For example:
Boller — a compact 13/16-inch Panfish profile with six glow colors and reflective UV additives.
Lucky J-Shad — a 1.18-inch micro paddle tail with glow colors and reflective UV additives.
Spike J-Shad — available in 2.36-inch and 3.55-inch profiles with six glow colors and reflective UV additives.
Spyro Tail — a 1.96-inch finesse plastic described with reflective UV additives and bright glow.
Double-Eye — a perch-eye-inspired soft plastic with reflective UV additives and bright glow.
FishDaddy also uses Glow + UV characteristics on other soft-plastic presentations, including the Quad Tail.
That means the same piece of soft plastic can provide a charged glow effect while also incorporating UV-related visual characteristics.
What Is Flake in a Soft Plastic?
Flake is different from both Glow and UV.
Flake consists of small reflective particles suspended inside the plastic.
Those particles do not create their own light and do not need to be charged.
Instead, they reflect available light.
As the soft plastic swims, rolls, shakes, hops, or falls, the angle of those reflective particles changes. That can create flashes and changes in contrast.
Different flake colors can also change the appearance of the bait.
Common examples include:
- Silver flake
- Gold flake
- Red flake
- Blue flake
- Green flake
- Holographic or multi-color flake
Flake size and concentration can matter as well. Fine flake can create a subtle sparkle, while larger or heavier concentrations can create more noticeable flashes.
FishDaddy currently uses flake directly in some soft-plastic color names, including Clear Holographic UV Glow Flakes on products such as Lucky J-Shad and Spike J-Shad.
Glow vs. UV vs. Flake
The simplest way to keep them straight is:
Glow — stores energy from a light source and continues emitting visible light after charging.
UV — uses additives that interact with ultraviolet light while UV is present.
Flake — reflects available light as the soft plastic moves.
A single soft plastic can contain more than one of these features.
For example, a bait can have glow material, UV additives, and reflective flake in the same color.
Each affects the bait’s appearance differently.
Why Does This Matter for Fishing?
Glow, UV, and Flake give anglers different ways to adjust the visual side of a soft-plastic presentation.
Glow can continue producing visible light after being charged.
UV additives change how the plastic interacts with ultraviolet light.
Flake reflects available light as the bait moves.
None of these replaces the fundamentals of presentation.
The plastic still needs the right profile, size, action, depth, cadence, and rigging for the situation.
Think of Glow, UV, and Flake as additional variables you can adjust when dialing in a bite.
Glow + UV Soft Plastics for Ice Fishing
Glow + UV soft plastics are a natural fit for ice fishing because anglers often fish vertically and can easily bring the bait back to the surface to recharge it.
FishDaddy offers several different soft-plastic profiles that can be used for ice presentations:
Boller — a compact 13/16-inch micro-forage profile for crappies, bluegills, and perch.
Double-Eye — a perch-eye-inspired soft plastic with a 3D eye on both sides and Glow + UV characteristics.
Spyro Tail — a 1.96-inch finesse plastic designed around vertical presentations and subtle movement.
Lucky J-Shad — a 1.18-inch micro paddle tail that produces movement with very little input.
These different profiles let anglers change more than color.
You can adjust size, profile, action, Glow + UV characteristics, scent, and presentation while staying within a soft-plastic system.
Glow + UV Soft Plastics in Open Water
Glow + UV is not limited to ice fishing.
FishDaddy also uses the same visual characteristics on larger soft plastics designed for open-water presentations.
The Spike J-Shad is available in 2.36-inch and 3.55-inch sizes and combines a baitfish profile with a kicking tail.
The Quad Tail uses four independent tails to create movement and water displacement, while its current product page also identifies six glow colors with reflective UV additives.
The important point is that Glow + UV describes a characteristic of the plastic, not a fishing season.
The same visual features can be incorporated into plastics designed for finesse ice presentations or larger open-water applications.
Where Does TERABITE Fit In?
Glow and UV affect the visual side of the presentation.
TERABITE addresses a different part of it.
FishDaddy soft plastics are infused with TERABITE on a number of products, adding scent and flavor components alongside the bait’s profile, movement, and visual characteristics. Current FishDaddy product descriptions list amino acids, omega-3 fatty acids, and pheromones as TERABITE components.
FishDaddy also offers a TERABITE UV Glow Fishing Enhancer, a topical product that combines Glow + UV characteristics with scent and flavor and can be applied to different types of bait and tackle.
That makes it important to separate the different parts of the presentation:
Glow + UV affect visual characteristics.
Flake creates reflected flash.
Soft-plastic profile and tail design create movement.
TERABITE adds scent and flavor.
Each serves a different purpose.
Does Glow Only Work at Night?
No.
Glow is easiest for anglers to see in darkness, but it does not have to be used only at night.
Under ice, at depth, beneath snow cover, in stained water, or during lower-light periods, a charged glow plastic gives you another visual variable to test.
That does not mean Glow will always outperform a non-glow color.
Sometimes fish will respond better to a brighter presentation. Other times they may respond better to something more natural or subtle.
Treat Glow the same way you would treat color, profile, or cadence: as another adjustment.
When Should You Try UV?
UV characteristics are another way to change how a soft plastic interacts with available light.
Rather than treating UV as something that automatically “works better,” use it as one more option when testing presentations.
You may change:
- Soft-plastic profile
- Size
- Color
- Glow
- UV characteristics
- Flake
- Jig weight
- Depth
- Cadence
- Scent or bait combination
The more variables you understand, the easier it becomes to make deliberate adjustments instead of randomly changing baits.
When Should You Try Flake?
Flake is useful when you want the soft plastic to reflect more available light as it moves.
It can be especially noticeable when a bait swims, rolls, shakes, hops, or falls because those movements continually change the angle of the reflective particles.
Flake also lets lure designers change the look of a bait without changing the entire base color.
That makes it another useful tool for fine-tuning the presentation.
Which FishDaddy Soft Plastic Should You Choose?
Start with the profile and presentation you need first.
If you want a tiny Panfish forage imitation, the Boller gives you a compact 13/16-inch profile.
If you want a perch-eye-style presentation, the Double-Eye gives you a very different visual profile.
If you want a finesse plastic for vertical fishing, the Spyro Tail provides a 1.96-inch presentation.
If you want a micro paddle tail, the Lucky J-Shad gives you a 1.18-inch baitfish profile.
If you want a larger baitfish presentation with more tail movement, the Spike J-Shad gives you 2.36-inch and 3.55-inch options.
Then choose the color and visual characteristics that fit the presentation you want to test.
That sequence matters:
Choose the profile and presentation first. Then use color, Glow, UV, and Flake to fine-tune it.
What About FishDaddy LED Lures?
LED belongs in a different category.
FishDaddy hard lures such as the Dirty Bomb Spoon and Dirty Bomb Minnow, along with the Dirty Bomb Live Wire LED jig, use electronic LED technology.
That is separate from the Glow + UV characteristics used in FishDaddy soft plastics.
The difference is straightforward:
Glow — stores energy from an external light source and gradually releases visible light.
UV — uses additives that interact with ultraviolet light.
Flake — reflects available light.
LED — uses an electronic light source to actively produce light.
These are different technologies and should not be treated as interchangeable terms.
For a deeper explanation of FishDaddy LED technology, see How Water-Activated LED Fishing Lures Work.
The Bottom Line
When FishDaddy talks about Glow + UV, we are primarily talking about visual characteristics built into our soft plastics.
That is different from FishDaddy LED tackle.
The simplest way to remember it is:
Glow — charge it and it continues emitting visible light afterward.
UV — additives interact with ultraviolet light while UV is present.
Flake — reflective particles create flash from available light.
LED — an electronic light source actively produces light.
For soft-plastic fishing, Glow, UV, and Flake are additional tools anglers can use alongside profile, size, action, scent, depth, rigging, and cadence.
Choose the right presentation first.
Then use the visual characteristics of the plastic to fine-tune it.
