Purchased for a 20 gallon terrarium housing my kids adult box turtle. Generates heat appropriately without light. Recommend and will buy again when needed.

Gets hot very quickly and would probably work great for smaller enclosures but struggles with my 55 gallon. My python requires the temp to be around 88-96F and with the lamp on top of the enclosure, it gets around 74-78F near the floor of the tank. In the mean time ive had to go to drastic measures to get the heat up until i find a better heating method

This keeps my 40 gallon tank at 80 degrees with both 100 on

not as hot as i was hoping but does the job

These work great! I am using them to heat a chicken coup in the winter. The chickens love them also!

Great bulbs for my turtle tanks

Delivers heat as advertised. Would have liked something with just a little lower wattage but nothing out there in that range.

Sturdy, well made, quick shipment and a good price.

The first bulb I used from the box failed within a day or two. The second one has worked for this last month, but Im concerned of the longevity of it after the initial failure. Ill be buying backup bulbs, but wont be ordering more of these.

Good value for your money
