Light Saber-Glowing Eel Jigging And Trolling Lure. Once activated, plasma sticks last minimum 8 hours at top brightness. Some last more than 24 hours total. They fade over time. Plasma sticks should be replaced after they dim too much. But still catch good when dimmed down. Each bait includes 2 of each color plasma. That’s 80 hours of trolling at max brightness. As they slowly dim, they still work so you can get a lot of time from each plasma.
