Hi,
I'm looking at installing a light fitting and thermostat in my enclosure to keep the temps up over night once the weather starts to get colder.
I would be using a ceramic heat bulb and wouldn't expect to need it all night, just through the coldest parts.
I've been looking at the reptapets thermostat which is pulse proportional, i've read how they work but I'm still a little confused.
Any advice on if a pulse proportional thermostat would be good for providing occasional night heat would be great.
Thanks

I think my first post was badly worded.
I don't want the enclosure to drop below 16C, so with a pulse proportional will it come on when the temp drops below 16C and then pulse to maintain a temperature of 16C until the morning warms up when it will just switch off again?
If that is right do they use more power than an on/off type, or no different as they are sending less power through the use of pulses.

I've found that with globes it's best to use a dimming thermostat as it makes the globes last longer. I've always used on/off thermostats with my globes, but i decided to use a dimming thermostat with my last bank of cages with great success.My globes last about 3-6 months with the on/off type but with my dimmer stat they are going on 3yrs now and i've only lost 1 of 6 globes so far.
So i highly recomend the dimming stat and i also recomend that you spend the extra couple of dollars and get the one with the magic eye, as you can set a night drop in temp for breeding purposes.

Nik | Yeh that'll work. Pulse thermos work with heat emitters (the ones you are going to use) but not so much with the light bulbs. It will absolutely manage your temps for you, keeping your warm end at 16 degrees will be no problem.

Not to mention the last thermo I had was on its way and the lights were flashing on and off not even a minute apart, it was frightening the animals. This one is great. I use the Microclimate B1 but knowing reptapet's products seem to look very similar to URS's stuff, I am sure it would work the same.
