Amphibious

I'm using a 75 watt w/ a dimmer. It hangs above my enclosure. ( I don't use it during the summer here on Long Island )
I think it works great as well. It's a tricky time of year. I find it is not as difficult to maintain temps once the heat comes on in the house.
Once the heat comes on in my home - focus has to be more on the humidity !

Just be very careful when positioning it , monitor closely when you fist get it up and running.
As mentioned, the dimmer is great with this bulb , because they are strong and things can be adjusted as the temps in the room affect the enclosure temps.
Monitor for hot spots !!!!
I have mine hanging above the enclosure pointed down to the center ( where no frogs can go) , above the water side.
This way it also helps pull up and create additional humidity as well.

The reason I changed to the ceramic was because the black and red heat bulbs seemed to reflect a lot of light off the inside of the dome at night.

If you would like a pic of how I suspended it from the ceiling of my ( very old ) basement , I'm more than happy to take it. It take only a few minutes to post a pic
