The full amount of your purchase is authorized (held) on your credit card to guarantee future payments so you need to have at least that amount in available credit on your card.

    The best!

    Bought two of your bulbs and two inexpensive infrared bulbs from Walmart for my DIY sauna. I can feel and see the difference. There is no doubt that your bulbs are superior and worth every dollar. I will be buying more in the near future. Thank you for making my DIY sauna feel heavenly.

    I am so glad I purchased a set of 4 "B" grade bulbs.for my home built sauna. They are A+ grade in my book. One bulb died shortly after purchase and was quickly replaced. Every contact with the company is met with a friendly response. The staff appear as passionate about the products as I have become.

    The Best Infrared

    I have been using sauna space bulbs for a few years and I love them! My sauna is the thing I miss most when we travel. I do love the sweaty detox, but even more than that I love how the infrared light helps me feel happy, especially on those cold, foggy days it can feel like a real high especially when followed by a cold shower!! My husband and I also have a beautiful, super expensive, wooden full spectrum red light sauna from one of the major companies and it’s nice, but I definitely prefer the feel I get from my sauna space sauna. When I have been using my sauna space consistently people tell that my skin glows. If I work my muscles too hard if I sauna afterwards it really cuts down on the soreness.

    I also like to keep a bulb near my computer in the morning to counter the blue light.

    The bulbs are kind of a no-brainer to counter life in the modern world.

    Worth It

    I have been curious about the Firelight Bulbs but the price made me hesitate. I was one of the first to demonstrate with photos how I retrofitted a FIR sauna with a 4 panel SaunaSpace back in 2016. Twice I have replaced the original bulbs with a competitors and haven't really noticed any difference. When I saw the Grade B Firelight bulbs were 30 percent off I bought 4 for my panel. I am a numbers person and preheat the sauna to 145 degrees. Turn the NIR off and turn the SaunaSpace panel on. Here are the differences:

    Competitor Bulb:

    Walk in temperature is 145 degrees. Turn FIR off and SaunaSpace panel on.

    Ten minutes later temperature is down to 135 degrees.

    Time to rolling sweat is 15 minutes.

    FireLight Bulb:

    Walk in temperature is 145 degrees (same procedure as above).

    Ten minutes later temperatue is 142 degrees.

    Time to rolling sweat 4 minutes, but actually sweating at 2 minutes.

    My experience is the FireLight bulbs are noticeably more intense, hotter and I get to sweating (which is the goal) much quicker. No sitting and waiting.

    I cannot compare these to Grade A Firelight bulbs , but Grade B apparently are cosmetically and tested to be as good. My experience is they are far better then what I have used in the past and worth the price.
