The ThermaLight™ bulb from SaunaSpace is the first-ever near infrared incandescent bulb designed entirely with health in mind.
Artisan-made using a mouth-blown process dating back to 50 B.C.
Featuring our custom-made tungsten filament that delivers 2-4x more red & near infrared irradiance than any other bulb on the market, all through a beautiful red-stained hard glass.
Next Level Red & Near Infrared Irradiance
Our ThermaLight Bulb has a uniquely designed filament that delivers a more ideal emission spectrum than standard incandescent heat lamp models and delivers two major advantages for the user.
MORE LIGHT THERAPY: a higher percentage of both photobiomodulation wavelengths red (600 – 700nm) & near infrared (700-1000nm)
BETTER HEAT THERAPY: a higher percentage deep penetrating radiant-heating wavelengths (1000-1500nm).
