come prima prova non mi sembra sia molto luminoso ,ho già dell'adesivo luminoso e funziona il doppio di questo proverò con più polverina

Exactly as expected, well-sealed and of really good quality. This powder is very fine which is perfect, it's also very bright even when charged with a phone torch!

I bought this after reading that watches use Strontium aluminate for their luminous parts and wanted to see for myself and try some for some ideas I had.I bought this based on other reviews and to be honest this is a quality product.One idea I had involved adding about half a teaspoon I estimate to some clear nail polish and then I painted a few coats to light switches around the house, the idea being able to find the switches in the dark. I did this yesterday and with a little help from a bright torch I charged the switches for no more than 10 seconds in the early evening and the switches were clearly visible at 0530 this morning within the darkness of my house.The bottles of nail varnish were still glowing this morning too.In comparison to other glow in the dark paints and glues I've previously purchased which glow for minutes this powder is on another level, it is really bright when charged and glows for many hours.I would advise to read the data sheet which is not provided but available from a link included on the companies card which accompanies the product, it includes all the necessary info such as use rubber gloves, don't eat it and so on. I bought the Aqua blue as well and that glows brightly too but not as much as the green which I understand to be the brightest possible.I'm really pleased and I wouldn't hesitate to buy this again.Update: 09April 2021. I have uploaded some pictures of the powder itself and as it was mixed in the nail varnish. The photos were taken in a dark room, the powder bags were exposed to daylight only for a short while, whereas the bottle pictures show one pair after UV blacklight illumination for about ten seconds and then taken again after being in the dark room for a couple of hours to show the amount of glow remaining. A great product.My experience is that things glow brightly for the first 20 minutes or so then gradually diminish over many hours.

Mostly worked, though some of the powder didn't glow at all even when fully charged, seems to me like it may have been cut with something cheaper to bulk it out.

Had mixed results with this, depending on the medium used. First off, I formed a suspension of this in clear varnish (about 20% by weight, which is more than is recommended to achieve an effect) and applied to a a plaster hand cast, (for a halloween prop). After five (yes, five) coats, the glow looks really good, initially. After being exposed to sun pretty much all day, I'd say the glow only lasts a couple of hours before it fades. I was hoping for longer. (Under UV light - photos 4-6 - the effect is really very impressive, however). So I’d give it three stars.I got much better results, however, when I disolved the pigment in casting resin (again, about 20% by weight). Here the effects in ordinary light were better than the varnish method, with the glow being both brighter and lasting longer. Normal resin is good, but using “clear-cast” resin gives the very best results. Under UV light, it is fantstic!Five stars for the resin use method.Would buy again.Review update (5-1-18);I’ve now tried all four of the SGXC glow in the dark pigments, (Green, Aqua blue, sky blue and Violet), using resin as the medium. To cut to the chase, I found;GREEN - brightest glow and seems to last about the longest time, though the aqua may last a little longer. Hard to really say.AQUA BLUE and SKY BLUE - Similar. Not as intense as green, but still good and give a “warmer” glow. I thought the aqua blue lasted a little longer than the cobalt blue and about as long as the green.VIOLET - easily the weakest glow and for the shortest time.To try and do a direct comparison of the four, I made four small resin casts, (clear resin gives the best results), using the same method and the same amount of glow pigment in each. (Initially, using a mixture of 20g of pigment and 20g of resin to coat the inside of the mould, until it was starting to set and then back-filling the mould with the basic resin, without any pigment).Once demoulded and fully cured, I then shone a UV light on each for about a minute, to give each one a good boost of light, although in the case of the violet pigment, I found it needed much longer before I saw any real glow.I found the green to be easily the brightest and most intense. It looks really good. The aqua blue and the sky blue gave pretty good glows too, although not as bright as the green. These gave a “warmer” glow, to me. Of all the colours, the aqua blue glow seemed, perhaps, to last the longest, or at least similar to the green.The violet pigment was easily the most disappointing. It didn’t really glow anything like as strongly as the other three, even after extended exposure to UV light. (Reading about these glow in the dark pigments afterwards, it seems that the purple pigment is known to need a lot of light exposure to get it to work, and even then the glow it gives is relatively weak and short lived, relative to the other colours).(Apparently, white and orange glow pigments are also pretty bad and red is even worse than violet)I tried to take a couple of photos to show the differences, unfortunately, they really don’t do the colours or the various glows justice. They all look much better in the dark with the naked eye (also, the bright green comes out yellow and the violet, dark blue for some reason, in the photos).Final Photo (left to right); green, aqua blue, sky blue and violet.
