The World's Highest Performing Glow Stones

Industry Leading Glow Duration Since 2008

Ambient Glow Technology™ is the world leader in high performance glow in the dark stones for concrete and asphalt substrates. Our NEW AGT™ ULTRA-X Glow Stones are engineered to provide the brightest initial luminosity and longest glow persistence in the world! According to DIN 67510-12009 Third Party Lab Testing, these Hyper-Luminosity glow stones exhibit an industry-leading Glow Power Rating of: 8796 mcd/m2 @ 1 minute.

Our AGT™ ULTRA-X Glow products are the latest in a line of state-of-the-art glow-in dark innovations. This time around, we've replaced traditional glowing pigments with an efficient microcrystal that can store and emit light for hours after being exposed to artificial light - aka photoluminescence! AGT™ products can maintain their glow in the dark qualities for 15+ hours. With only 8-10 minutes of exposure to daylight or UV light, they will continue glowing long into the night.

AGT™ Glowing Reviews


AGT's stones glowed the brightest and had the shortest decay rate. Hence, they serve as the best company to go ahead with for concrete or asphalt glow projects.

I’ve been a glow in the dark artist for over a decade and have tried a multitude of products. Was completely excited when AGT first came out and was blown away by the products performance both in luminosity and glow retention.

Used the emerald yellow glow stones for a customer project and the results were absolutely amazing! Customer was extremely impressed with the results and luminosity of the glow stones.

We have tried some other glow stone products on the market and they all pale in comparison to AGT. Your glow stones produce a 50%-75% greater glow intensity & duration than ANY other other glow marble and glow glass chips we have ever tested.

I have tried other glow stones on the market such as glass glow stones and THEY JUST DON'T GLOW! AGT Glow Stones have the brightest and longest lasting glow on the planet! Don't waste your money or time on anything else!
