REPTIZOO Dimming Thermostat, PID Temperature Controller with Memory Function, Reptile Thermostat for Reptile Heat lamp, Specifically Designed for Light Heat Bulbs & Heaters

This can handle a 250-watt lamp, but I found that was excessive, so I down-sized to a 125-watt lamp instead (which is safer). Fixed-position lamps tend to be too hot during the day and too cold at night. This dimmer automatically deals with daytime and night-time temperature differences of the room and maintains the selected target temperature.The PID controller works very good, with only gentle over/under-shoot- which is vastly superior to, and much easier than manually adjusting the lamp up and down all the time. This works so well that I consider it a life-support necessity, and purchased a spare just-in-case.You will need to find a good location in the heated zone for the temperature sensor. My hot-blooded ducks sometimes sat on the sensor, which made the dimmer gradually turn the lamp off for short periods until they moved away- just as it should ;) .

Really good thermostat and easy to use. I set it to 85 degrees for basking temps, and it hasn’t let the temps rise any higher. Easy to turn off and on as well. Temperatures are accurate and the thermostat itself is easy to read.

I use this to modulate my ceramic heat emitter in my bearded dragon enclosure. It works great and has never messed up. Just make sure to place the sensor in a proper location to take ambient temperature. Would recommend to any reptile parent! Accurate, easy to use, and takes a second to set-up.

Works well, easy to use. The suction cup on the temperature probe very quickly failed though.

I found after trying this thermostat that it works best sunder substrate for an under tank heater. I tried using it as a thermostat for ambient air temperature. I measured with an infrared thermometer that the spot below the thermometer probe was 4-7 degrees higher than the probe itself. I think this is largely attributed to the probe being encased in a waterproof plastic housing. I have a second thermostat unit with an exposed metal probe that registers a smaller margin of error when used as an ambient air thermostat. Easy to use and set up with clear factory instructions included.

Why did you pick this product vs others?:Already had one works great.

Product review on the ReptiZoo PID Mini thermostat. Absolutely love these! We use DHP day and night. Day temp set to 87° and night temp 81°. It gradually heats the enclosure, which seems more natural to me instead of 81°, BOOM, 10 mins later 87°. It's 5:30am in Central Florida and I just set the 2 thermostats to 87° for the day. The ambient temperature will reach 87° around 10am and be maintained throughout the day. The thermostats do allow a 5° temperature variation DOWN, but when I check my Govee's there is not major fluctuation, maybe a degree or less. See pics. Don't mind the temps looking off, I have my Govee's in odd spots right now so they look low but they're more on the cool side right now, but you can see in the graphs they are no more than a 1°F temperature drop at any point. We tried Pymeter dimming thermostats and loved them, but they emit a high tone that drove my dog nuts. Then we tried Inkbird, but they were on/off, and even though we had it to turn off at only 0.5° below the set temperature, the temperature fluctuation was ridiculous. It would often get 6-8° below and up to 4° higher than our set temp. Then we tried CavaChew and they were ehhhh. They allow that same 5° temperature fluctuation as the ReptiZoo but they really had fluctuations that I was able to measure with our Govee's, so ambient temp fluctuated a lot. We have our probes dangling beneath the DHP to get accurate heating temps (took some playing around with for correct basking temperatures), but after a day or 2 we got it. They are inexpensive, super easy to use and set up. Both our BP noodles now come out to bask or explore nightly as soon as the lights turn off and don't go back to their hides til the sun comes up. We do routinely measure the basking areas to ensure they aren't too hot, and never exceed 93° at night. They hide all day, so basking temps are a bit higher during the day, but they never come out during the day. We were previously using CHE for daytime and DHP for night, but switched solely to DHP 24/7 and it's worked wonders. Temps are on point, humidity is on point (higher right now for shedding), and not over drying our substrate. We're only having to add water once a week and mix the substrate every 4 days. Overall, love these thermostats and highly recommend them.We will be switching to PVC 4x2x2 by the end of the year and using radiant heat panels, so I'm going to have to research how these thermostats work with those as far as probe placement and accuracy. Excited to see what's to come.

Unfortunately this thermostat didn’t work out for my setup. It was not quite what I needed to control my reptile’s heat lamp effectively, so I returned it.
