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.

At first I was sent the Completely wrong glow color.. I ordered white powder with white glow.. got white powder with a beautiful turquoise green glow… contacted customer service and the seller fixed it immediately without hesitation 🥰💯 got me the right color at absolutely no inconvenience to me! I will definitely order all my glow powder from this seller! It charges fast! And glows for quite some time unlike other powders…

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.

Glows bright under my led uv lamp. Very white and fades to aqua color. I didn’t get the keychain so I don’t know about that, either way it was a free gift.
