Great video Bert. Short yet imformative, to the point and not one claim of medical miracles due to a particular wavelength. I appreciate you making this.
Great job. I didn't have a proper setup where I am living to do a sauna of this quality. So I just kind of did a basic version with plywood, small nails. One thing I would do differently is added some ventilation and even set an alarm clock in the room when using it. I live by myself and I fell asleep one time when resting in the sauna (good thing I woke up after about 30 minutes).
Hi, I agree that this design puts the bulbs the correct distance from one person sitting in the center of the 4x4. (Best to be 18-24 inches from bulbs and they need to shine directly on your skin.) ., But I would point out that those bulbs get burning hot so there should be some sore of metal grid to avoid accidental touching. I'm not sure they wouldn't burn the wood holding them also? And the interior wood should not be stained since there will be out-gassing of petrochemicals as a result. Perhaps one could design the lamp holder to work with those metal fixtures that have two protective bars in front of them?
Hi Todd, Nice to have your input. I'd like to offer my comments - Yes the bulbs get very hot and although the wooden lampholders provide shielding and some protection, a wire cage over the bulb could be fitted if felt necessary. I provided an 1/8 " clearance all round between the bulb and the wooden lampholder and there has been no signs of burning over a long period. To explain further - the lampholders were designed to be free standing to make it easier for wiring up. Also the 2 aluminium strips I fitted in the corners of the cabin are to provide the choice of 2 different heights when hanging the lampholders. I agree no treatment should be applied to the wood on the inside of the cabin.
Hey Bert, thanks for sharing the video. I was wondering where you found those bulb sockets, if you could share what make/model they are ? Did you enclose the top ?
Hi Julian, thanks for your comments. The sockets are standard UK ceiling droppers from B&Q diy store or on-line. Originals were bayonet but changing to screw type to suit new lamps. Top of cabin was enclosed.
@@bertfullerton6043 thanks for the quick response. I am located in Canada. Will a lamp socket rated at 660volt, 250watt be okay to use with the infrared lamps which are 250W, 120v ? How many wires come from each socket ? Would there be three ? one as a grounding wire ? Sorry not too sure about the electrical part.
@@ScratchProgramming Hi Julian, A socket with higher rating than electric supply should be OK. Wiring is difficult to explain here, I suggest you talk to a local electrician if you have no experience, sorry I can't be of more help. All the best and greetings from Scotland.
We in Spain use PHILIPS PAR38 IR 175W, maybe in USA is GENERAL ELECTRIC PAR38 IR 175W, it is better because use less electricity to heat, whit this big box maybe better put 6 lamps, beter than 4 grettins from spain!!! you must put the temperature to 45 degrees maximum, and 39 degress minimun!!! to sweeat a lot!!!!
dieguito alfonsito Thank you for your comments, much appreciated. For info. one lamp failed leaving 5 but still sweat within 5 to 10 minutes. Greetings from Scotland.
Some lamps replaced recently are Intelec 250 W Infra-red 230V/ 50 Hz E27 screw (bayonet type not available now), not specified if near or far infrared.
careful the proximity of lamp to dry wood, could get smokey or worse, make sure bulbs don't touch and that lamp projects past where bulb radiates to wood hole edge. bulbs get HOT, you dont want to place them in a way that you could slip and fall against one....it would be a bad burn
Hi, no need for refletive or thermal insulation. Infrared penetrates the skin and sweating should start in 5 or 10 minutes. By the way, I started with 6 bulbs but when 1 failed I found 5 was plenty.
I just read a Dr. Mercola article where he says that heat lamps give off far infrared and only 10% is near infrared. That's the first I heard that. Is it true?
By definition, a "heat lamp" has to contain mid and/or far infrared, because those are the wavelenghts that give off heat (compared to the visible light spectrum as well as the near infrared that don't give off any heat). So right off the bat, it's can't be 100% near infrared. Secondly, all the infrared spectrum (composed of near infrared, mid infrared and far infrared) is completely invisible to the human eye. And yet, as we see in the video, these so-called "infrared" bulbs actually emit a visible and very bright light (so it can't be part of the infrared spectrum which is invisible). So in reality, in these so-called "infrared/near infrared" heat lamps, the near infrared is only 10-20% of the light emission (as shown in the spec sheet of the Philips 250W infrared heat bulb, which is the typical infrared bulb used in all these near infrared saunas). And then for the bulk of the light emission, it's mid and far infrared, which is why they give off so much heat in the first place.

Thanks for your comments. A little ventilation and an alarm clock is a good idea. Enjoy your sauna, cheers.

God bless you!
Thank you!
Wow fantastic Thanks so much for Sharing 🗣🙏🏻
Can you give any more details about the electrical? I was going to plug a few bulbs into an extension cord but don’t want to burn my house down

is this made out of pine?
Thanks for your comments. I used pine t & g panels from a diy store.
Good idea, except the MDF part, what is emitting toxic fumes at least for 6 month.
Thanks for your comments. MDF floor was sealed and tiled.

Are the heat lamps near infrared by definition or do you buy globes labelled far infrared or near infrared?

Agreed. I made sure ample clearance between lamp and wood. 12 hour test showed wood unmarked.
Hi did you find it hot enough without reflective insulation thanks
Hi, no need for refletive or thermal insulation. Infrared penetrates the skin and sweating should start in 5 or 10 minutes. By the way, I started with 6 bulbs but when 1 failed I found 5 was plenty.
@@bertfullerton6043 thanks I will construct mine this week
Can this cause cancer in the long run that is the question
Sorry, can't answer that but IR has been used for many years to relieve aches and pains.
I just read a Dr. Mercola article where he says that heat lamps give off far infrared and only 10% is near infrared. That's the first I heard that. Is it true?
According to Wikipedia infrared heat lamps emit near infrared
Ok, thank you!
