Introduction: LEDS. Make Them Glow When They Are Not Turned On.

I just recently bought some green glow dust (glows in the dark) from Solar Color Dust.

This and clear nail polish is all you need to turn regular white light LEDS in to glow in the dark LEDS.

Step 1: More Colors

Here are more colors: Green, banana, blue, aqua, lime, orangsicle, peach, cotton candy, papaya, blueberry.

Green, blue and Aqua are the only colors that look pure white when lit up and when off but not charged. The rest have a noticeable color other than white when lit up and not charged when viewed not directly in the beam. The colors are a little washed out in the pictures of the leds when lit up but are actually quite noticeable.

All of them shine a pure white beam of light with no noticeable tint in the white circle of light.

Violet and lilac did not work well in this application.

Aqua and green have the brightest glow.

Banana glows green according to my eyes.

Blue and blueberry are dim.

Step 2: Paint and Dust

Just Paint the underside of a LED with clear nail polish. Then quickly, before the nail polish starts to dry, sprinkle / dump a lot of glow dust on the underside of the led. Then point the led down so the excess dust falls off. Save the dust that falls off. It is still usable for the next led. Let the led dry and power it up. If you think the led needs another coat then repeat the above steps.

Step 3: Glow Leds in Use

The first picture shows the LEDS getting charged up on my led tester box. As you can see from the next picture, the glow from the led can be seen in normal room lighting. 

Adding a little glow dust to your next LED flashlight project could be fun and it could help you find your flashlight in the dark.

That's a good idea - you could completely coat a UV LED in the powder fir a brighter glow.

But, could you make the spam in step 3 a bit more subtle?

This would be awwwwsome for Steampunk gadgets, Sith chestplates, Ironman, Samhain, pc cases... okay, I'll shut up now :)

Yes, and electric jewelry, signs that stay lit after a power outage, low current LED projects that power the LEDS one tenth of the time with a cyclic recharge pulse.

Lol! Alright already showoff, don't blow a fuse! (Joke)

Hello Honda Enoch,

I think you answered your own question.

It reminds me of a Dave Barry article I read where Dave writes about reading an article about the worlds biggest rubber band airplane. He says guys will read that and go “cool” and girls will read that and go “why”. Anyway, I can’t speak for anyone else but I like LEDS. I like them for more than their utilitarian value. That is just one of the reasons why I made 5 different super capacitor flashlight. I can enjoy them and not spend money on batteries. I also like things that glow in the dark. So this puts 2 things I like together in one package. .My wife and kid like them too. Years ago my wife asked me to make here a flashlight that you could select between multiple colors of leds. I have made her 3 different UV flashlights (one was just not enough). She has made glow in the dark nail polish with the glow dust and we have things all over the place that have been painted with the stuff. From the practical standpoint, I had no problem finding “Ray”, my 400 farad super cap flashlight when my alarm went off at 5 am. Ray was still emitting a faint aqua glow.

PedroDaGr8,

Nail polish is cheap but if that does not work you could try polyurethane in a small can (minwax for coating furniture) or clear krylon. Just spray it in a cup to use it as a liquid.  Both are cheap and easy to find

Just don't use a styrofoam cup. Most spraypaints dissolve the foam right away, leaving you with a big mess.
