Stuart Semple LIT - the world's glowiest glow pigment, 100% pure LIT powder

I tried a few different glow paints recently for neck markings on a couple basses. While others are decent and also market as being super bright. This stuff is legit. Do buy the acrylic base to go with it, and it's worth mixing your own and loading it with as much or little powder as you like. Note that you'll have to balance ease of application with how intense your paint will be, how many coats, etc. It far outpaced several other available brands/types of glow paint both in glow and in 'charging'. Some notes: -have care in mixing the powder. It can get all over stuff. put something under the container when you open it for the first time and then use that to scoot the overflow back into the jar. Mix in small quantities. You can't hold onto it once mixed. One use at a time. -Buy a decent UV flashlight for charging if you're not using it for decoration or whatever or if it's in a location that won't get good natural light to charge. Spend the $$ for a good 6-10w LED handheld. -Initial glow can be very strong, and it's persistence does indeed last hours. I tried this out with 5 minutes of charging and then used in complete darkness for over 2 hours and it was plenty bright. I would suspect that yes it would be good for 12+ hours, but obviously will dim substantially. -The super-base they suggest is a good option. It's stood up to wear and tear and regular handling now for a month or more without chipping, peeling or wearing off. As a test I did scrape off a bit to see if it caused damage and it came off with some work and left no marks or damage. It adheres well and seems to stay put. The attached picture is obviously in a well lit room with about 1 minute charging and about 30 seconds after charging so it could dim down a bit. So yeah, bright enough to see in light.

This is, as it is described, a loose powered pigment. It isn't for someone who is unfamiliar with mixing paints. I mixed it into clear polyurethane, at the ration suggested, for three coats. And it worked great. But you have to constantly mix it to keep it from settling. Not a problem, just part of the process. Also, that mixture, when dry, is rough. I lightly sanded it and put 2 coats of clear, straight out of the can polyurethane for a glossy finish. And man is this stuff bright. I got some of the mixture under my nails, and for days, I had a glow in the dark French manicure. It would startle me every time I walked into a dark room. The mixture works well on fabric in a dry brush technique. I don't know how long it will last, but it is going strong at 6 months. That was a random impulse, I spilled some, and turned it into a heart on my t-shirt. Happy accident.

This stuff is easily the brightest glow on the market! But you will need to charge it with a significant amount of light and heat to make it attain its maximum luminance. I let the small jar of the powder sit out in direct summer sun for a few hours. Afterwards the product was so bright it would cast shadows on objects even indoors with all the lights turned on, and I have super bright 2,000 lumen light bulbs throughout my home! It will maintain that maximum brightness for about an hour nd will hold half its maximum brightness for 6 hours or more and reduce to very low around 8 hours but still very visible in a dark space. I've found it will hold some measure of a glow well into 10 hours before needing to charge again. I suggest mixing it with clear nail polish for surface applications and have a super bright flashlight on hand to give it a quick charge as needed.

I have done extensive experiments with this and here is what I found. It’s glowy. Really just a good, nice, glowiness. I compared Lit with Gluminous and they are indistinguishable; both are commendable glowers. They will glow all night from any ordinary charge. I find my slippers and my phone in the predawn morning using this paint. I must advise that the best results have been from using the Stuart Semple Superbase, either with Lit or Gluminous. Other bases just don’t seem to work as well for some reason. The price seems reasonable because a little goes a long way. Oh, and the other guy’s review about being careful when you open the jar - yeah, that’s no joke.

This product is advertised as "the world's glowiest glow pigment" which intrigued me, so I ordered some to see how it compared to various other glow pigments I have. Compared against your run-of-the-mill, glow-in-the-dark paints you might find at the hobby shop, this will blow them away no problem. It is definitely brighter than most commercial glow pigments. However, compared for brightness side-by-side against Art 'N Glow neutral green glow powder (the brightest of their products), it is practically impossible to tell them apart. After initial exposure to either UV or regular daylight exposure, the LIT powder seems to possibly have a barely perceptible advantage (I believe this is due to the powder structure, more on that in a bit) but it really is nearly impossible to tell if there is actually any difference at all. After 30 seconds in the dark, the two are absolutely, completely indistinguishable from one another. From here, they both seem to continue to fade at about the same rate. As far as practical brightness is concerned, they are nearly identical, and I suspect that they are actually the same material molecularly. Because these two products are so close in brightness and color as to be nearly indistinguishable, I will compare the two of them exclusively for the rest of this review. One advantage that the LIT pigment has over Art 'N Glow is that the powder is a visibly finer consistency. I don't know what the actual particle size is, but it is extremely fine and I think this accounts for the initial, barely perceptible brightness advantage; I suspect that the finer particle size gives it a greater surface area which helps it to emit a tiny bit more light during those moments of initial glow. This is especially apparent where the dry LIT powder forms clumps due to static cohesion (being finer makes it almost "fluffy" compared to the other powder), the surface area of the clumps is no brighter than Art'N Glow, but within the crevices it seem to glow brighter due to greater surface area inside those crevices, causing the emitted light to bounce and reflect more. The finer particle size should also provide an advantage when mixed in paint, as it should theoretically settle out of suspension more slowly and thus need to be mixed less frequently and be able to be applied more smoothly. This might also be an advantage if you intend to use the pigment with an atomizer type paint sprayer. Art 'N Glow's particles are fine enough for most uses and shouldn't create a problem for most applications, but LIT's pigment has a clear advantage in this regard. Compared to Art 'N Glow, which comes in tough resealable plastic bags, this comes in a small plastic screw-top pot/jar. Depending on your feelings on the matter, this could be either a pro or a con. To me it is a con, because the bottle is difficult to open without making a bit of a mess, since the fine powder coats the jar threads and this powder is then lost when the top is opened. You can see the amount of powder that spilled out of the jar when I opened it to take comparison photographs. This happens every time the jar is opened. I would suggest opening the jar over a piece of paper to collect any pigment which drops when it is opened. The flat plastic bags provided by Art 'N Glow, while seeming to be simply a cost saving measure, are actually much easier for me to use, compared to the narrow opening of the plastic pot. The screw-top container is also single-sized and costly, compared to Art 'N Glow's plastic bags which cost almost nothing on their end and the savings seem to be passed on, especially as they come in a variety of sizes and the price per ounce drops significantly the larger the size you order. Starting at around half the price of LIT for the same 1 ounce, if you order larger sizes you will pay far less per ounce. In summary, this is without a doubt a high quality glow pigment. I don't know if it is the "world's glowiest," but it definitely stands as a contender against the glowiest ones I have found at least. However, unless your application requires the pigment to be the smallest possible particle size, and/or you consider the small plastic pot to be worth the extra money, then this would not be my first choice for price to value, especially if you plan to use a larger amount of product. Photos: LIT powder next to opened jar, lid, and over-spill from opening; Art 'N Glow next to sealed plastic bag, after a 20 second exposure to 45 watt 365nm UV light. 1/4 tsp of each powder for an even comparison; the Art 'N Glow self-levels compared to the LIT which forms clumps due to the difference in particle size. Comparing brightness, the crevices in the LIT appear brighter, but when comparing the surface of the clumps only, it is actually a bit less bright. Overall, the two are very close in brightness and should appear nearly indistinguishable when used in a paint medium.

Painted racing stripes on my car with this, I have three stage pearl so the stripes are three stage aswell with the glow powder mixed in the pearl stage, put the whole little bottle cup thingy of powder in those two stripes so gives you an idea of how much to use if anyone's going to attempt this. I did about 5 coats on pearl/glow stage then clear coated the whole hood. Glows bright in the daytime , cant wait to see what it's like at night!! I will update a few months from now to tell how its holding up!

I used this product on my ghost Viking ship. I made the sail using old cloth. I mixed the pigment with white glue and water to paint on the sail. Looks great, The rest of the craft came with glow paint, but I added more pigment to it. Not the greatest picture but the glow is good,

Was a little concerned with the review that said this only glows for 10 minutes. That was not my experience. After charging with a light it was so bright you can see it across the room with the lights still on. That super bright glow fades after a bit but the product continues to glow nicely for at least 8 hours.. tested this at night and fell asleep before getting the full range of glow time. Be aware this dust is extremity fine and tends to spread around when handling the product. Don't work with this anyplace you are not prepared to have an afterglow without some cleaning.
