Inkbird Day/Night Heat Controller Review: Two Setpoints, One Plug
A review of Inkbird's day and night heat temperature controller: two time cycles, heating-only dual outlets, 1200W rating and where it fits in a bearded dragon setup.
The on/off thermostat that knows what time it is, for keepers who want a genuine night drop.
The verdict: A heating-only on/off controller with two independent time cycles, so a ceramic heat emitter can hold one temperature by day and a lower one overnight without a second device. Buy it if you run a light-free heat source and want an automatic night drop. Skip it for a halogen basking lamp, which needs dimming control, and skip it if your room already falls into the 65 to 75F night range on its own, in which case you may not need night heat at all.

What it does well
- The day and night cycle is the feature. Reptiles evolved under a daily temperature swing, and automating it removes the temptation to leave the heat at one number year round.
- Heating-only means no accidental cooling relay to misconfigure, which is a simplification rather than a limitation for reptile use.
- Probe calibration is unusual at this price and it matters, because an uncalibrated probe is a confidently wrong thermostat.
- Two outlets let you run a basking-side emitter and a second heat source on the same schedule.
- The 1200 watt rating is far beyond anything a single enclosure needs.
Where it falls short
- It is still on/off control, so it is the wrong device for a halogen or incandescent basking bulb. Light sources want dimming.
- Many bearded dragons in normal indoor rooms do not need supplementary night heat at all. Before buying, measure the room overnight, because if it holds above roughly 65F you may be solving a problem you do not have.
- No light output means no visual check that it is working. The display is the only feedback, so read it.
- The two outlets share one probe and one schedule, so it cannot independently control a warm end and a cool end.
- Cheap wired probes are the usual failure point on any controller. Route it so the enclosure door does not close on it.
What owners report
Owner reports on Inkbird controllers are consistently good on reliability and consistently critical of the manuals, which are written generically and take a read-through before the time cycle logic makes sense. Several reptile keepers describe setting the night cycle once and never touching the unit again, which is the outcome you want from a thermostat.
The more useful debate is whether night heat is needed. A bearded dragon tolerates and arguably benefits from an overnight drop into roughly the 65 to 75F range, and many homes provide that for free. Our guide to whether bearded dragons need heat at night works through when supplementary heat is genuinely warranted, and the answer is usually a cold room rather than a rule.
If you do add night heat, it must not emit light. Coloured night bulbs are still light to a reptile. A ceramic emitter or a deep heat projector on this controller is the right pairing, and our deep heat projector versus ceramic emitter comparison covers which to pick.
Who it suits
- Keepers in a cold house where the enclosure would otherwise fall below the safe overnight range.
- Anyone running a ceramic heat emitter or deep heat projector who wants an automatic day and night difference.
- Keepers who want probe calibration rather than trusting a factory offset.
Who should skip it
- Anyone controlling a light-emitting basking bulb, who needs a dimming thermostat.
- Households whose rooms already sit in the 65 to 75F range overnight.
- Keepers who need independent control of two zones.
Alternatives worth considering
Inkbird ITC-308 Digital Temperature Controller Thermostat
~$36
The same family without the day and night schedule but with a cooling relay, so it can drive a fan in a room that overheats. Choose it if summer heat is your problem rather than winter cold.
Check price on AmazonREPTIZOO Dimming Thermostat, PID Temperature Controller with Memory Function
~$28
Dimming control for the main daytime heat source. Most complete setups end up with a dimming thermostat on the basking lamp and an on/off unit on any night heat, because the two loads want different control.
Check price on AmazonArcadia Deep Heat Emitter 50 W for Reptile Enclosures
~$31
A light-free infrared source designed for exactly this role. Pair it with the night cycle so the enclosure stays warm without lighting up a sleeping animal.

A T5 10.0 UVB Fixture, the One Thing You Cannot Skip
Metabolic bone disease is the most common preventable illness in captive bearded dragons, and it comes down to inadequate UVB. A linear T5 tube across the basking side does what a coil bulb cannot, and the tube needs replacing roughly annually even when it still lights up.
Frequently Asked Questions
Do bearded dragons need heat at night?
Usually not. A drop into roughly 65 to 75F overnight is normal and healthy, and most heated homes provide it without help. Supplementary night heat is for genuinely cold rooms where the enclosure would fall well below that. Measure your room overnight before buying anything.
Can I use a red or blue night bulb instead?
No. Coloured bulbs still emit visible light, and light at night disrupts a reptile's day and night cycle. If you need night heat, use a source that produces no light at all, such as a ceramic heat emitter or a deep heat projector, controlled by a thermostat.
Will this control my basking lamp?
It will switch it, but it should not. On and off control makes a light source flash on and off through the day, which is stressful and hard on the bulb. Use a dimming thermostat for the basking lamp and keep this one for the light-free heat source.
Where do I put the probe for night heat?
At the level the animal sleeps, away from the heat source itself, so it measures the environment rather than the emitter. Secure it so the animal cannot dislodge it and so the enclosure door does not pinch the cable.
Does a thermostat make a heat rock safe?
No, and heat rocks should not be used. The danger is prolonged contact with a hot surface, and a bearded dragon does not reliably move off one in time. Documented contact burns are the reason experienced keepers treat them as unusable regardless of any controller.
