Replacement Red Light Bulbs

Genuine replacement incandescent red light therapy bulbs for SweatBox saunas — the same full-spectrum bulbs we build in at the factory. $25 each, shipping included.Match the wattage to your sauna exactly. All three wattages use the same E26 screw base and will physically fit any SweatBox socket, so it is on you to pick the right one. Fitting the wrong wattage can damage your sauna's electrical system and voids the warranty. 100W — The Original Indoor SweatBox (150°F): all 4 bulbs. Outdoor SweatBox: the top 8 bulbs. 150W — Indoor SweatBox with the High Heat Upgrade (180°F): all 4 bulbs. 200W — Outdoor SweatBox: the bottom 4 bulbs only. Not sure which you have?
