Custom-Engineered Infrared & Red Light Bulbs
The Hot Box Sauna Infrared Bulbs are built specifically for the Hot Box heater assembly. Blown thick red-stained glass and a solid tungsten filament deliver more heat intensity and deeper red light penetration than standard incandescent bulbs. 600–750nm red light pairs with penetrating infrared waves that target joints and bones.
The 300W bulb is designed for the Standard Hot Box Sauna. The 400W bulb is designed for the XL. Compatible with V3 and V4 heater only. Non-refundable.
