RubyLux bulb works wonderfully
I have had lower back pain for about 50 years. Having been a staff RN in a hospital for 30 years, my lower back was injured and re-injured numerous times. The pain has varied in degree from just irritating to so severe that its sudden appearance has caused me to fall. I have had surgery once about 30 years ago and since have been treated by chiropractors, physical therapists. energy healers, an acupuncturist, physiatrists, and have used ice packs and heating pads, all with some level of temporary relief. I finally decided to try near infrared light therapy after a year of my back getting steadily worse. I bought a RubyLux Infrared Bulb. The first bulb burnt out after the first use and Bambi Iversen at RubyLux could not have been more helpful in getting a new one to me. The bulb is great! Several times I have felt the pain diminish until it's gone while doing a treatment. I have used heating pads many, many times and the level of heat required to bring pain relief and relaxation is very close to being painful. The pads also also warm up and cool down (I don't use automatic pads). Not so with the RubyLux. It provides a steady level of warmth that does not get hot as long as you follow the distance directions. The relief it provides includes a level of relaxation that I was never able to achieve with the heating pads. This relief lasts for about 3 or 4 hours and appears to be cumulative (due to traveling vacations I haven't been able to use it as regularly as I have wanted to). Being retired, there is no reason that I won't be able to use the lamp daily, at least. I would recommend the RubyLux bulb without hesitation, and have, to anyone who experiences joint pain. The only suggestion I have is be sure to get a clamp on light with a strong enough clamp to hold the lamp and bulb in any position.

That's definitely radiating some Near Infrared!
Before I ordered this I was using a brooding light from a farm store, also 250W. The difference in the feel of this heat is intense; penetrates more deeply, very relaxing and I know it's doing what it's supposed to do! Worth the extra $ to have a genuine long-life bulb. I'm just using it in the farm store brooder lamp clamp-on though, so I'd recommend a professional fixture where you can adjust the height over a bed or massage table. Good product!

Provides a lot of Pain Relief for Cancer Patient's Neck/Spine
*Scroll to 3rd paragraph to read about pain relief* I've been battling cancer for 2.5 years. There's 6 tumors, one wrapped around a blood vessel, pressing against the nerves behind my spine, causing tremendous pain. It's the kind of pain that's had me on opioids like morphine for 6 months going on 7. I finally got tired of the pain and went to "Hope4Cancer" clinic in Tijuana, Mexico for 1 month of treatment (I live in Texas btw). While I was there they had me do a Near Infrared Sauna session every other day. I noticed that their NIR Sauna was way hotter and more effective than mine at home. By hotter I mean it was like an instant furnace upon flipping the switch, and by more effective I mean I sweated waaaay more and I actually had a lot of pain relief within 5-7 minutes of each session. I've had a NIR Sauna for 2 years but haven't had the kind of pain relief that Hope4Cancer's sauna gave me. My sauna had x8 150-watt bulbs; Hope4Cancer had x6 250-watt bulbs. So while I was there I did some research on the best near infrared bulbs on Amazon and I ended up trusting RubyLux over all other brands. There are three statements by RubyLux that helped me make the decision to go with these bulbs: "emits NO far infrared rays[.] . . . free of toxic mercury, Teflon and fluorinated fumes[.] . . . [and] Each bulb is inspected, guaranteed and engineer-certified." I had to drop out of college to battle cancer 2.5 years ago so I forget how to correctly quote like that^ but I hope I did it right. So first impression is that RubyLux is specifically concerned about making sure we know that there is absolutely NO far infrared rays, which is very important for a cancer patient like me needing very specific treatment. The other two things (free of toxic stuff and each bulb inspected and certified) sealed the deal. When the bulbs came in I replaced 8 of my 150-watt bulbs with 5 RubyLux 250-watt bulbs. Let me tell you-- I was in awe when I turned on the sauna. It was an instant furnace just like at Hope4Cancer, but my sauna is a little smaller than theirs so mine gets even hotter, quicker! Normally I've been able to handle 30 minute sessions with x8 150-watt bulbs, but with x5 250-watt bulbs I was only able to tolerate 10 minutes on my first session. It took me 4 sessions to be able to work my way up to being in there for 20 minutes and really, I don't think I'm going to go up to 30 minutes again because I simply don't need to with how effective these bulbs are. I have pain starting in my spine around T1-T2 and then it branches out to the left into my left rhomboid and also wraps around my neck where I have other tumors that are swollen up. I'll give you an example of what happened this morning. I'm trying to taper off of Morphine but not able to do so as quick as I'd like because this morning I woke up in a lot of pain that I don't normally have, and I'm assuming it's because I dropped in dose of morphine. So anyway, I'm in a lot of pain and I go straight to my sauna at 6AM. I get in, meditate on Jesus and pray for Him to bless this treatment, and within 5 minutes I'm thanking Jesus for pain relief. I could feel a warm soothing sensation penetrating deep through my muscles and onto the tumors causing the pain. It's like I could feel the tumors relaxing and changing from screaming to humming (idk if that makes sense). Imagine (sound wise) going from banging on a desk to rubbing a desk. That's like what happened my neck/spine; it went from screaming to soothing. After 10 minutes I was just loving it; I really wish I could stay in there all day long because of how much pain relief I had. But of course, after 20 minutes I had to get out and shower, and now it's been 1.5 hours and I'm still having pain relief. Well, I took a morphine lol, but still I can feel the after effects of the sauna and the morphine doesn't cause this. So if anyone is battling cancer and needs pain relief, you have my recommendation (I'm a cancer patient in pain) for RubyLux.

Best home sauna lights hands down!!
Ordered two of these in the past and moved to a new city so I had to re-order my home sauna equipment. while, there are “more affordable“ options on the market. I wouldn’t think of using any other lights for my home sauna set up! These bulbs are amazing!! The brightness is amazing and the heat is perfect for my home sauna as well as targeted area therapy! Only thing that mashes me nervous is it will make creaking noises from time to time but I’ve never had any issues with the bulb. 10/10
