Simple Deluxe Reptile Heat Lamp Bulb - Ceramic Heat Emitter 40W/60W/100W/150W/250W - No Light Brooder Coop Heater for Amphibian Pets, Chicken Incubation & Reptile Tanks - Ideal for Terrariums, Vivariums & Poultry Farms

I ordered these to keep my chickens warm during the winter months. One could argue it's unnecessary but my wife and I found that if you can keep them warm during the cold winter months the chickens will continue to lay eggs. Initially we tried using infrared heat bulbs but quickly found out it would have been a waste of money to continually replace them as they were constantly havening their filaments break. I came across these and figured I would give it a try. They produce a lot of heat quickly and unlike heat bulbs these don't have the same fragility issue and can still be screwed into cheap heat lamp sockets you can purchase from any hardware store. We've had these ceramic heat emitters for over a year now and they are still working strong! 5/5 work as intended and last much longer than their traditional heat bulb competition!
