The bulb is very reliable even in harsh winter conditions.
This light does more than they say. We had a bad ice storm and our pump house was in jeopardy. We have used heat lamps in it for 20 years now. It was cold, very cold, more than it has ever been, and it stayed that way for over 10 days straight. Well, I had to use a new bulb, the Bulbmaster 250 watt bulb. It stayed on for over 10 days straight, without a break. I am impressed and also relieved, it was one less thing to worry about. 10 days straight of minus 7 to minus 15 degrees F was hard on us here in the south. We are glad we had these bulbs.

A quality heat lamp at reasonable prices with great customer service backing it!
These do what heat lamp do! my wife was bummed that her red therapy light broke so I ordered these to surprise her with a replacement for her to come home and rest under. The quality is great, these heat up the moment they are turned on but never get too hot. Fit any standard sized heat lamps housing with the standard light screw base. These were priced competitively with box stores but as always Amazon proved their value in ordering from them Im also posting to give my appreciation to the dedication and amazing customer service Amazon always brings to the purchasing experience. One of the bulbs in our 2 pack came broken (filament dislodged during shipping) and Amazon was right there to get me a replacement bulb overnighted to me. I merely inquired how to remedy the broken bulb and was greeted with and immediate replacement. A great thanks to Amazons customer support staff and all they do for us shoppers.

good procuct
the heat is wonderful but it ( the bulb ) does not take much abuse...i.e. the chickens love to play with it and tend to overdo it and the bulb does not last as long as it should

My patients love the warmth and pain relief
I purchased the BULBMASTER when Amazon was out of stock of the Phillips brand. So far, this seems to work just as well. My patients enjoy infrared heat during their acupuncture treatments. Infrared heat helps reduce pain, relax muscles and circulate blood. They are so well loved by patients, I keep two lamps in each treatment room. One is directed the low back or torso while the other keeps their feet warm. During a treatment, people's bodies tend to cool down. The infrared heat keeps them comfortable and relaxed. These bulbs are dimmable, which is a necessity with the KS Choi Infrared lamp fixtures I use. I prefer this heat system over a TDP black plate lamp for two important reasons. The black plate lamps are a safety hazard because no light is emitted so it's not obvious when left on. With red bulb lamps, there is no mistaking when the light is on. Another reason I prefer these is that infrared bulbs heat instantly and I can place it at the optimal distance for each patient. Black plate lamps take at least 10 minutes to heat up. It's a guessing game on how close to place it to each patient's body. I have also tried the RubyLux NIR-A Near Infrared Bulb Grade A. Both are good products, but the Bulbmaster sells for half the price.

Good, reliable warmth. Also good for chicken coops in cold weather.
I’m on a well system. I have a well pump above ground, and a house service pump that pumps from the cistern to the house. I build a tent around this piping, and keep my pipes from freezing, by using these lights, 2 of them. My pets go in there to warm up as well.

Just what we needed
They work wonderfully. We have outdoor cats that have heated beds in our pool shed but it was supposed to go down to minus thirty-something and I was concerned. My darling hubby bought these bulbs and replaced the two overhead lights with them to take the edge off the cold. The pool shed now glows like Hades at night but my mind is at ease. Good price, good quality, work just as they should.

Muy buena calidad. Mejor que la bombilla que venía con mi lámpara. La uso para mantenerme caliente durante el invierno mientras trabajo en lugar de usar un calentador.

Quality light
Light comes as a 2 pak. Lights infrared are good, 250 watt, 120 volt. Would be nice if longer life expectancy but are supposed to last up to 2000 hours. Overall a good product.
