1oz (30g) WHITE Glow in The Dark Neutral Invisible Strontium Aluminate Glow in The Dark Fluorescent Pigment Powder

At first, I thought this was yellowish-green (Grellow, I will call it). Then, I fired up a 35 watt UV LED bar (there's one on amazon for 12 dollars and it's phenomenal) and a very low watt led bulb... each affected the color differently so I realized the glow is dependent on factors I'm still not 100% certain about (like light wave length). I also have a 3,000 lumen o-light flashlight that will get this white. If you then shake it around (in the bag) you mix the powder that did not get bombarded with photons and the stuff that's glowing and you may then get different hues - that's NOT the powder working incorrectly. It DOES work and works quite well. The light they included, while super weak (and FREE), is in the correct spectrum and will make a pea-size spot glow white for a second. I am impressed and happy with what I got.

I was on the fence about this product for a while. When I charged it in the sun it glowed white but turned blue quickly. Charging it with a spotlight resulted in a greenish glow. I put it away and moved on to another project thinking that this wouldn't work. Today I decided to get out the UV lamp that I use with UV resin to see what would happen. After charging it for just 30 seconds under the UV lamp I got a very bright, very very WHITE glow that was bright enough I could easily read with it. After an hour it started to take on a blue cast as the glow dimmed but after three hours it was still visibly glowing.

I’m the black light it was white as described but in the dark it was off yellow.

The UV light that came with it gave the powder a yellowish green tinge and I was a bit disappointed. Luckily, I have a decent UV source on hand and I charged it up with that for a minute or so and it took on an almost blue shade before becoming a decently consistent shade of white for a while. One important thing to note is that it is calibrated for the human eye not a camera lens, so it looks more blue in the photo whereas another I got on the top left is calibrated for a camera so it looks more greenish yellow to human eyes, additionally this one is a bit brighter so it's not completely 1 to 1.

The description says white to white glow but it’s actually white to green. After reading other reviews I decided to try different uv lights and it was still glowing green. On top of that the glow fades rapidly compared to other glows I have used. The project I was planning to use it for I now have to redo since it is the incorrect glow color.

So I bought this to mix into my gel polishes. I mixed it into some clear, and frankly, there wasn't much of a glow. It's not non existent, but it wouldn't really stand out. I tried sprinkling some on top of wet gel, and it didn't soak up the gel in a consistent manner, but that definitely helped show the glow more. I will definitely have to mess around with this more, but I think if you're mixing this into a builder or something, you'll get a much nicer result. It doesn't mix into gel suuuuper smoothly, but it's smooth enough to apply. It's just a bit gritty. That being said, just because it didn't work for my use doesn't mean it wouldn't work for others. I think the portion was pretty generous (for me at least) and in the bag, the glow is pretty good. It's a bit of a greenish glow, but it's not suuuuper green, so it's ok. I might try out a different color, but I think in my case, I'm very off getting an actual glow in the dark gel polish.

This is great glow powder. I was looking for a better glow powder as the cheap stuff only glows for minutes.This will literally glow all night after charging it in the sun for a while

Best quality white glow powder I've found so far. Long lasting, white glow. I am obsessed with this powder and will definitely be ordering more powders from them.Other powders I've used in the past either don't glow for long, or aren't a truly white glow.
