The Hot Box Sauna

Hot Box Sauna Infrared Bulb

The Hot Box Sauna Infrared Bulb is the red light and infrared bulb that heats the Hot Box heater assembly, sold in 300W and 400W. Blown, thick red-stained glass and a solid tungsten filament deliver more heat intensity and deeper red light than a standard incandescent bulb. Each one pairs 600 to 750 nm red light with penetrating infrared waves that target the joints and bones. The 300W bulb is matched to the Standard sauna and the 400W to the XL. That keeps each heater running at the output it was set up for.

It fits the V3 and V4 Hot Box heaters. Bulbs are the one part the sauna's 12-month warranty leaves out, so a spare on the shelf keeps your sessions running.
