Question 1

What wavelength does this bulb emit?

Accepted Answer

Heat lamps do not output a specific wavelength. They output everything from red at 650nm to 1100nm infrared. If you google incandescent heat lamp then click on images, you will see what the spectrum looks like. Hope that helps.

Question 2

Is this a Teflon-coated bulb?

Accepted Answer

I called the Philips Company and asked specifically about this model bulb.I was informed that the company puts a silicon coating on some of their bulbs and that this bulb specifically has has no coating on it.There is a bulb that does have a coating, and it's number 159327.UPDATE:The bulb that I received appears to have a coating on it. Two reasons why:The coating can be smelled after it has run for a few minutes.When comparing with three other bulbs that do not have a coating on it, there is an mark that appears on the bulb I received that is missing on the other bulbs.comparison photo called philips-amazon-415836-comparison.jpg - https://drive.google.com/file/d/0B3EYYHNgU811clRneUk0dEZ3OFk/view?usp=sharing The box I received from this product has this information on it820915Ordering Code:250R40/HR 120V 4/1 TPI bought these bulbs from Home Depot, and they also had coating on them.For the use of an infrared sauna, any coating is not optimal. In the case of a bathroom, a coating would likely be optimal.

Question 3

Can this be used outside of a bird cage, or will the bars heat up?

Accepted Answer

You'd want to keep it a foot or two away from the cage, so that it won't burn the birds. It will heat up the bars some, but if you experiment with it and watch it closely, you can figure out how far/close to put it to the cage so your birds are warm but not getting burnt from the bars.  It's a good, warm heat lamp for sure.

Question 4

Can this be used for  NEAR infrared lamp saunas?

Accepted Answer

I built a near infrared sauna with these bulbs to replace the far IR sauna I had before (I guess these bulbs have both as described in the other comments, but this was what my health practitioner advised, that these red heat lamp bulbs are "the" bulb for near IR).  amazon also sells dr larry wilson's book on how to build your own sauna....  it doesn't have to be fancy, I know a woman with limited space who managed to attach these bulbs with sockets from Lowe's to an adjustable mic stand that she carries into her small shower stall so she can detox sauna that way.  Best, G.
