Infrared Bulb

Introducing the Hot Box Sauna Red Light & Infrared Bulb

Engineered for performance, our custom 300W and 400W bulbs deliver deeper red light and stronger heat than anything else on the market.

Crafted with blown, thick red-stained glass and a solid tungsten filament, these bulbs pack far more heat and intensity than your standard incandescent bulb.

Feel your mitochondria tingle with 600–750nm red light paired with the penetrating infrared waves that target your joints and bones. 

For our customers, we highly recommend using 300W for our Standard sauna and 400W for our XL.

Get ready to feel the difference!

Only compatible with our V3 and V4 heater.  See our video to see if you're good to go! (Link)
