Does anyone use 150 watt basking lights?

Okay, this seems dumb, but I have a 40 gal breeder. I was using a 75 watt basking bulb in the early fall, switched to 100 watt when it started getting colder. My digital probe thermometer has started reading the basking spot as topping out at 92 degrees after an hour of sitting there. I added the 50 watt to the hot side to try to increase the ambient air temp, but to no avail. The cool side is dropping to 75 during the day too, since I took the 50 watt off that side. Chester NEVER uses the cool side, if he gets too warm he goes in his hammock next to the basking spot. So, I bought a new sun dome with a higher wattage rating and i'm waiting for my reptisun 10 and 150 watt bulb I ordered to come in. Obviously I'll check the temps before I put him in there, but does anyone else have to use such high wattage to get the right temps. I mean, there will be 200 watts of heat in that viv... my room temp is 58 to 60 and his viv is next to the window which doesn't help, but I need reassurance I won't cook him!!! :?

i use a 200 watt bulb, and my beardie is fine. a 150 watt hardly got the basking spot to 100 degrees for me, now its at around 108 degrees with the 200 watt.

What size viv do you have?

It's the room temp that is probably killing you...

In my 40B I use a 60W Halogen PAR30 Flood/Spot light bulb for basking, a standard 60w and a standard 40w to keep things balanced in my tank.

Halogen produce more heat at lower watts, so maybe try a 60w - 75w Halogen PAR30 bulb.

I am using a 150 watt in Sarth's 40gal tank, and his basking spot hovers between 102-108 depending on what the temp in this room is (which is usually around 70ish). The cool side is probably around 75ish and I have seen him go over there occasionally, his poos are evidence of that.

Aww your profile picture is precious ❤️‍🩹
Hey! I'm planning on ordering a 4x2x2 for my next beardie but I'm worried about lighting. I have a UVA and a UVB but they are small (the UVA just being a bulb and the UVB being 12 ish inches?) My house is drafty so I need a strong light that puts off quite a good amount of heat, any suggestions?
