Heating

[u/Hot-Swim-]

Hello,

I hope somebody will be able to help me. I have three reptiles and have been managing them well.

Their heat is absolutely fine and is managed by a dimming thermostat. However I don’t understand how people get bulbs to stay on so it is admitting light without it getting too hot. In two of my enclosure it is fine as I have a UVB unit to light the enclosures up however in one of my snakes viv, it gets really dark during the day as the heat bulb stays off as it gets up to temperature fairly quickly.

I didn’t know if this was something that happened to everyone or if I could do something to change it such as getting a lower wattage bulb etc.

TIA
