Step 8Test the fluorescent liquid
Start by taking a highligher pen and put it into clean water to get some of the fluorescent dye dissolved in it. Then put some of it into the bulb and dilute it with more water.
Connect one of the UV leds to some power (don't forget the resistor if you're not using the triad you created in the previous step) and shine it into the solution to see how it looks.
Try some different mixtures to get the effect you like the best. You really don't need much of the dye to get a nice glow.
