Yep so for a baby that age you want a basking spot of 80. Just a temp gauge that has a probe on it. a tiny zip tie to secure the probe in place on the branch below the heat lamp. If baby is screen crawling the top you want to lift that fixture up off the top about 4inches then test the screen with your hand to ensure it is not too hot. I would use a regular white incandescent bulb no stronger than a 60 watt.
