I use this for my acupuncture patients to keep them warm during a treatment and also to provide penetrating heat to the affected area. Patients like how it feels, it seems to relax muscles. I have used these and conventional red-incandescent bulb heat lamps. I think I would agree that a conventional heat lamp makes the surface of the skin hotter and therefore you need to keep them farther away. The minerals supposedly help the heat penetrate deeper. Maybe it is just a claim but I suspect the difference between this and a traditional red heat lamp or the sun is that they focus and produce heat at the surface of the skin and therefore deeper tissue might not get as warm without the skin feeling excessively hot. Why not 5 stars? I have had several of these lamps (including this one) and the reliability has been variable, but I can't say for sure if the current one from KS Choi is exactly one of the models I had in the past (I did buy one from them years ago). Basically it works as advertised.

Works great so far. Clients love it and makes my job easier. Waiting to be able to use it myself.

Great lamp, provides good heat source. A bit flimsy construction, as the screws have come loose. This was easily fixed, but you need to move the lamp by the base (not by the top of the frame).

How many watts does this need to operate? I used to have one like this a long time ago (not sure of the brand) and I loved it and gave IT five stars. I would love to have another. Being on solar, power consumption is very important but I can't make out the photo. Thank you whoever. :)

this meets my needs in always.
the packaging was ok.
the few assembly requirements were a little difficult because they were shoddily poured in the plastic injection.
it took a little finagling to get the stand to work. i think the company could have a little bit more control over the quality in manufacture of that piece.
the item itseld works well, is effective and i recommend it.
