Does it matter which dome I use and CHE question

[Imjoloki]

I'm wondering if it makes a difference which dome I use for my beardies basking light. Its a 100watt light I have these 2 deep domes ones wide the others skinnier I have a couple doubles too. Do they give off different levels of heat? Which would be better out of the 2 in this pic? Also I'm expecting a 100 watt CHE from Amazon today can anyone give me advice on best way to use it and when. I have a 40 gallon tank. Arcadia t5 100 watt basking light and a 50 I turn on in the mornings to help heat up faster. I'm expecting a digi probe thermometer also so I'll be checking temps all I have atm is the much hated stickies.
Any help would be much appreciated

The CHE needs a dome w/ a ceramic socket and the correct wattage I use a deep dome for mine - it sits on the top of the screen middle of the tank - its a 100 watt on a 120 gallon tank - I only use it when temps are below zero here - when its run it keeps the tank around 73 degrees - you want temps in the tank at night between 65-75 --

I would use the one on the left for your ceramic bulb and the one on the right for your basking bulb.

Ok.. I have 2 of the bigger ones tho.. should I still use these two? And do i run the che 24/7 or just at night? My house stays around 74 but it feels cooler

If you have 2 of the wider ones those are the ones I would use. Me personally I’m not a fan of the deep domes. To me the it blocks some of the heat because it’s at a higher distance. It’s not what the house feels like it’s about the tank. I have to run my Che day and night to keep the temp where it needs to be. This is what I check my temps with

Your tank will go to house temps at night - or close to it- the deep reflector domes reflect the heat into the tank-- your probes will measure the ambient temps at night w/ the basking lights off- just hang the probe on the side of your tank-- I have never used a wide dome w/ the che I have always used the deep domes as recommended - IR guns are good but do not read off of certain materials used for basking- I have them as well but rely on my probes
