It's Dark Out There!
Self-Illuminating
Our products use gaseous tritium as the power supply. As the gas decays, a constant stream of radioluminescent light is generated that becomes visible as ambient light levels fall.
Lasts up to 15 Years
These products are in it for the long run! No recharging, batteries, switches, or spare parts are needed during their uniquely reliable service life.
Quality Products
Firefly products are routinely used all over the world by those operating in low-light and darkness. Their unique reliability to work normally even in the most adverse climatic conditions helps to enhance operational efficiency and safety.

Since the emission of light is done by relatively cooler materials, luminescence is also called cold-body radiation. Gaseous Tritium's...
