I saw the basking lamp holder needs to be porcelain. But which size? Exo-Terra glow light porcelain clamp lamp have sizes 14, 21, and 25cm. Or there's a Zoo-Med wire cage clamp lamp. I'm looking at getting the Swamp basking spot Exo-Terra 75watt lamp if this will suffice. I take Squirt outside regularly for natural sunlight so wasn't planning to get the MVB one.
