Fluo-Pop Ups are more than colored PopUps
Fluo-Pop Ups are UV active baits. UV light has the shortest wavelength of the light spectrum and therefore penetrates the water the deepest. Invisible to us, but makes fluorescent colors brightly visible. Normal bottom baits or balanced baits do not have this property and their visual appearance disappears as the water depth increases. The best way to show the effect of the different lures and the luminous properties of the pop-ups is to compare the images under the different lighting conditions.

Conventional baits
Our conventional colours are lost with increasing depth, depending on the wavelength of the light. The color with the longest wavelength disappears first, i.e. red, then orange, followed by yellow, green, blue and finally violet. In practice, we should therefore first determine our natural water color in order to be able to make a statement about the effect of our bait color. This can be from deep blue to green to brownish and acts like a color filter. If we know these, then we can roughly estimate which wavelength range penetrates the water particularly well. If we now choose a bait with the same or longer wavelength, then this will be easily recognizable under water. For example, green (Monsters Paradise), yellow (Birdfood Banana), orange (Mega.Grill, Oriental Spice) or red (Uncle Bait) bait will all be visible in the greenish water. The right choice for curious fish. If you choose a bait with a shorter wavelength, e.g. a bluish or a brownish color which is not present in the light spectrum (BigFish, Monster Liver, Elite), the color will cancel out and it will be harder to see. Good choice for shy fish. Another variant is the possibility to offer a bait in different colors. The same lure in different colors. One is more noticeable and the other disappears visually earlier. Perhaps the reason for the extraordinary catches with Crawfish and Scopena.Love. A good choice if you do not yet know the behavior of the fish in a body of water. The visibility is therefore the combination of the light spectrum at the respective depth, body color and the selected bait color. Visibility changes over the course of a year due to changes in water color and natural turbidity. As a result, certain colors work better in spring than in fall, or vice versa.

Fluo PopUp
By adding UV color to the bait, you increase the color intensity of the bait. The Fluo PopUp! In this way, even at greater depths, where not all colors of the light spectrum arrive, something that is actually invisible becomes something conspicuous. If only UV light (ultraviolet = shortest wavelength) can penetrate to our bait, it will definitely be "luminous" visible. Only the color intensity of the fluo pop-up is weakened or completely absorbed by the color of the water. A normal bait in the same color would not attract attention here. Attention, but this "glow effect" is not always an advantage. The deeper and cloudier the water, the greater the positive effect. The shallower and clearer the water, the more unnaturally glaring the bait appears, and there is a risk of a scare effect. Direct sunlight reduces this glowing effect and lets the pop-up appear in a normal color tone. Cloudy skies, however, increase this even more. In complete darkness there is no fluorescence at all. All cats are gray at night. Ultimately, it is important to find out which combination the fish jump at in the respective body of water. Unfortunately, there is no golden rule.
