I thought it may be the ceramic heater bulb so changed it for a spotlight bulb so i know when it s coming on.
Dimming thermostat with ceramic bulb.
I have this one.
Ultimately it s better to use a 600 watt grow lamp running at full power than to dim a 1000 watt bulb.
You must be sure to use a ceramic light fitting though as it can melt the plastic ones pretty quickly.
On off stats usually come in either 100w or 300w and pulse dimming thermostats are usually rated.
It s nothing to do with the bulb as the spotlight is only coming on now and again.
They will shorten the life of a light emitting.
The effects of dimming your grow lights.
Remember to check your thermostat can cope with the wattage of the ceramic bulb.
The heat light on the stat is sometimes coming on and sometimes off.
I use a 60w ceramic heater for my 3ft x 1 5ft x 1 5ft vivarium.

I ve been using my komodo dimming thermostat for ages with no issues at all.
Komodo ceramic lamp and bracket.
Pulse proportional thermostat these are made specifically for ceramic heaters.
Now put the thermostat probe through the vent or you can drill a hole through the vivarium if you wish.
We place the probe on the hotspot and secure it using nail cable clips u clips if you have a branch under the heat bulb and guard you would place the probe there and secure it to the branch using a cable tie.
For heatmats cables use an on off thermostat for ceramic bulbs accurate heatmat temperatures use a pulse thermostat for light bulbs use a dimming thermostat always check that the thermostat you use is suitable for the wattage of your heat source.
It s understandable that some growers may want to dim their grow lights but it s best to keep your lamps at full power.
The push button dial system of the thermostat will prevent accidental changes of the set temperature if the device is being handled.
They send out pulses of energy to the bulb to change the amount of heat the bulb gives out.
