What Size Tea Light Should I Use With My Wax Melt Burner?
 
I would  recommend pairing smaller burners with 2 or 4 tealights and larger burners with 4 to 6 hour tea lights. This should help to avoid both underheating and overheating.
It’s important to never leave a burning tealight unattended. Always place your wax melt burner away from drafts and also keep the naked flame away from any material or
objects that could catch light. And most importantly, keep your burner out of the reach of children and pets.
