I recently got a Dubia colonly and I’m trying to get the temp in their enclosure to 90 and I’m having hard time doing so. The lady at pet co recommended I get a nano heater and I went with a size bigger just to be safe and it still wasn’t enough. Thank god I didn’t listen to her as my roaches would have probably froze. But basically I bought all the stuff to fit that bulb so my question is if I go and pick up the 100 wat bulb is it the same size as the 60 watt bulb? I know it will fit in the same socket but I mean as far as dimensions go? Because my ceramic light now is just barely not sticking out of my dome housing and I fear if it’s any bigger it will stick out and could possibly be a fire hazard. Here’s a pic of how I have it set up now.
