So far so good! No complaints!

I set this up for baby chicks and the heat that it transmitted was minimal, may be good for an aquarium but not in a open space

I reach my temperature im aiming for. I do use a thermostat with it. It shut it off when it reach set temperature then went it drop 5 degrees it turn back on. It lasted me a week with one bulb. I dont know the thermostat kill it fast cause it one and off , on and off but i guess with money you save its a good back up.

We tried this brand for the first time. The first bulb died after a month, 740ish hours, no where close to the 9000 - 15000 as stated in the listing. It could have just been a bad bulb, but its not at all what we expected. I tried to contact the seller but that is not an option on this item.

Just had it operating one day but so far so good- heats up my tanks where I want them without the light output :)

This product is by far the best one Ive purchased. Ive had it for about 2 months now and hasnt burned out. It continues to keep the cage at the same temperature as well. For the money,v its super great quality.

worked very well

I like them great heat output

only produced a tiny amount of heat, a heat bulb would be better. also, it didnt work after I plugged and unplugged it.

I’ve purchased these bulbs before and they worked great. But the last time I purchased one of them blew out within an hour of installing it in the fixture for my Russian tortoise. I replaced it with the second bulb in the set which only raises the temp from 76 to 85 despite being on a thermostat set much higher. I didn’t want to have to go through the hastle of going to the post office to return both bulbs and let my tortoise go without heat again but am definitely disappointed with how the quality of this product has decreased since the last time I ordered.
