i cannot afford a whole set-up right now, so i purchased a single bulb. i am enjoying it ( i believe i have seen an improvement in inflammation), so are my senior pups!
- AKAndrea K.Verified BuyerRated 5 out of 5 stars4 months agoSignificant reduction in inflammation!
My father has recently been diagnosed with a rare genetic mutation called Vexas, which causes severe inflammation of the cartilage throughout the body, particularly in the nose and ears.
After only 10 minutes of exposure to the sauna space infrared bulb, there was a significant reduction in inflammation. Regular use has also been helping to reduce the pain and redness.
I also have a sauna space bulb and look forward to using it daily to ease aches and pains, rejuvenate my skin, reduce screen fatigue, and simply enjoy basking under the glow.
- KKarenVerified BuyerRated 5 out of 5 stars7 months agoUseful light for so many ailments!
I began using this infrared light in 2021 when my dog was hit by an suv and broke her leg in two places. I applied the light throughout the day for five minutes per session. She made a miraculous recovery and we never had to amputate that leg.
The pictures below show the broken leg and the middle picture is her other leg with wounds she sustained. The third picture was taken the day after I applied infrared light to that particular leg. The healing process was quick!
Since then, I’ve purchased a second bulb for my 86 year old mother to use. She loves it. She uses it on her lower lumbar area. I can’t say enough great things about this light. I love it!
- GBGina B.Verified BuyerRated 5 out of 5 stars1 year agoBulb & Bodacious
I've had my Sauna Space for about 2 years now and love it and use it every day. The bulb lasted a long time and I replaced it for the first time recently. Came quickly, beautifully packed and super easy to install. I'm so happy I bought this product and would like one day to make the investment in a larger system. I've recommended it to others. Feels so good! Thank you for this really nice company that makes lovely products.

Love this light bulb, especially in the winter. I use it daily. It’s been helping my skin and my mood! The red light and heat is calming and therapeutic, my dog loves it too!
