TechnoGlow Green Glow in The Dark Powder, UV Black Light Reactive | Strontium Aluminate Europium Dysprosium

My fishing weights and jig heads glow like crazy! I shine my small UV flashlight on my weight before I drop it down to 400 feet. It keeps glowing for hours.

None of these things are magic, so don't expect too much. But this formula definitely works better than some cheaper stuff I recently bought. It "charges" more than the cheaper stuff just from ambient light in a medium-bright room. Leave both side-by-side for an hour, turn off the lights, and this one is brighter. And it's better at passing the light along to the inner parts not directly exposed to light. With the cheaper stuff, only the very surface gets charged, even with powerful direct light. This good europium-whatever powder will be glowing even on the bottom part, so I assume you can mix in a denser amount into whatever you are making to maximize brightness and it will still get fully charged.

Used it in a workshop to paint door frames and counter edges. Great when closing up, turning out the lights and having some navigation to get out. Used it in a bathroom too: mixed with fiberglass to waterproof a bathtub wall. Even hours later, there is enough glow to use the bathroom without a nite light. Bonus fun: Stand against the bathtub wall, flick the lights on for a bit and then off. Step back and you have this cool silouette - endless fun!

Absolutely AMAZING! My children are avid users of fidget spinners and were looking for another level of excitement in their spinning experience. Most high end spinners with glow elements use Tritium which is a radioactive isotope of hydrogen and while toted as being safe I just couldn't take the chance as a responsible parent. Techno Glow came highly recommended from my social media spinner group and for good reason. This stuff is amazing! Upon arrival I opened the envelope and it was actually glowing from the residual light allowed to pass through the packaging. A quick test charge with the lamp and BAM, the bag was filled with an amazing green glow. The weekend project is to mix the powder into an epoxy and load it into sectional areas of my kids spinners. They are so excited!

I always wanted to try this higher performing strontium aluminate glow in the dark powder. This should be the color that glows the longest. For hours they say. But when I charge this in the sunlight or with a powerful UV flashlight. The glow dies off fast. Within an hour I can barely see it glowing. I bought some cheaper, common zinc sulfide based powder that was in a similar bag. Charged both my UV flashlight till both were bright. The let them sit in the dark. At 15 minutes, 30 minutes and45 minutes. Both powders glowed the same brightness. Seems I paid a lot for cheap powder.

I made some resin items with glow in the dark powder. Some colors glow more brightly than others and this one is quite bright.

I got this product a few days ahead of the estimated shipping time, and it also had a detailed sheet including safety information. I had used this product for an enamelled piece and it still glowed well after being fired in a kiln at 1500 degrees farenheit. If anyone wants to use this product for glow in the dark enamelled pieces I would recommend this product as well as this seller.

First, it was delivered three days before it was due. The green glow is BRIGHT ! I thought it was going to be somewhat dim and not last very long, but it lasted thruout the night ! Great when mixed with clear epoxy resin if you work fast.
