Who is Ambient Glow Technology and Why AGT™?

We are the market leader in high performance glow aggregates for concrete & asphalt. Since developing the current industry-standard - AGT™ Commercial Grade glow stones in 2008, Ambient Glow Technology remains on the cutting edge of glow stone manufacturing technology.

Our full-service photoluminescent aggregate supply & project consulting AGT™ Enterprise Program offers clients a consultative approach that focuses on project vision attainment – not just product selling. The program evaluates many of the variables that must be considered when specifying high performance glow aggregates in a project such as:

  • Luminosity Characteristics & Requirements
  • Glow Aggregate Material Grade
  • Optimal Glow Aggregate Sizing
  • Preferred Glow Aggregate Color
  • Type of substrate
  • Glow Aggregate Loading Rates per sf/ m2
  • Environmental Lighting Conditions
  • etc.

Committed to Quality & Performance

It should be noted that not all glow aggregates being marketed on the internet are alike.

Each material varies in:

  • Material Quality
  • Glow Duration
  • Price

In order to ensure that our clients have access to the most state-of-the-art glow aggregates in the world, we created our R&D division AGT™ Glow Labs. In 2015, we unveiled the world’s first DIN67510 Part 1 compliant super-luminosity glow aggregate AGT ULTRA™ – which boasts the highest luminosity and glow persistence technically possible.

AGT™ Best Practices for Glow Aggregate Application

To ensure that the end result is what you envisioned - our dedicated AGT™ Applications Team stands ready to share its over 10 years of real, hands-on glow in the dark stone application experience with your concrete contractor of choice..

How Much AGT™ Product Will I Need?

Coverage rates per sf/ m2 per lb. are available on each AGT™ Glow Stones Product Detail Page and are based on our recommended loading rate of a glow in the dark stone every 3-4".



  • Glossiness: Glossy
  • Translucence: 0%
  • Structure: Closed
  • Texture: Medium
  • Hardness: Hard
  • Temperature: Cool
  • Odor: Mild


  • Fire resistance: Strong
  • UV resistance: N/A
  • Weather resistance: Good
  • Scratch resistance: Good
  • Weight: Light
  • Chemical resistance: Moderate
  • Renewable: No


  • Non-Radioactive
    AGT™ is non-toxic and safe for use in all types of environments.
  • Outstanding Luminosity
    Exposure to sunlight for 8 minutes produces an afterglow of over 12+ hrs. Exposure to artificial light such as Halogen, Fluorescent etc. for approx. 15-25 minutes produces an afterglow of over 12+ hrs.
  • Performance
    The luminosity of AGT™ ULTRA and COMMERCIAL GRADE Glow Stones is dependent on glow stone grade and glow color. For example, Emerald Yellow ULTRA grade 12mm glow stone exhibit an initial burst intensity of    12 510 mcd/m2 @ 1min. and then begins to degrade over time once removed from a light source. For more information, please refer to AGT - ULTRA TECH DATA SHEET #003 & AGT - COMMERCIAL GRADE TECH DATA SHEET #004.
  • Stability of Physical & Chemical Properties
    AGT™ works perfectly between +500ºC and -30º C. It is also resistant to high and/or extended exposure to ultraviolet radiation and does not discolor under 300-watt high mercury lamp for 1000 hours at 35ºC - 40ºC, 80% humidity. AGT™ is unaffected by most chemicals. They are also not affected by extreme climates such as high heat, sub zero or wet environments. AGT™ Glow Stone DO NOT expand or contract in concrete or any other substrate.
  • Fine Particles
    The AGT™ line of high performance glow aggregates range in particle size from 350 mesh glow sand to 12mm Glow Stone.
