If you do not wish to build your own, this guy is still the expert.
I built mine 2 years ago and use it every day. It's great and I just put in my bathroom and go. I got a big piece of board, three ceramic holders for the bulbs and 3 infrared light bulbs. I put them in a triangle and wired them together with connector wire, one positive, one negative, putting an extension cord on the final bulb.
It's all explained on the website, but actually this lady at Lowe's showed me how to do it and it was really easy. No men at the Home Depot would help me with it--sorry guys, i know you are not all like the but....
This stupid boy at work told me I probably needed to have a boy come out and check it out, but I have had it for 2 years and I have yet to shock myself.
In any case the website is really good. He is an expert in candida. Talks about mercury poisoning and also how some candida is related to copper imbalances sometimes created by taking birth control
