Why wouldn't you just spend $5 on a meth pipe? One with the glass tube and a spherical section on the end with a small hole in the top to drop 'material'. It would be much cleaner, although if you think smoking out of a lightbulb is a good idea....especially considering you're supposed to be '18+' on this site and if you're that old still doing this...euch....
The lightbulb vape sucks. Don't waste your time. I'm speaking from experience, it barely gets you high, extremely inefficient.
Had one I used dabs with. It broke. Never got another one. I felt strange when I seen myself in the mirror
