LG heating element voltage?

[Roward74023]

Im working on throwing together a styro bator (i dont really need it...its just one of those things on the bucket list). Ive got 2 extra heating element (from 9300s i believe) i want to experiment on using but i cant find a chart for the input.

I assumed wire it through a 12v adapter, but that didnt seem like enough. Any ideas?

Also, any idea if it could handle being on a dimmer switch instead of the simple on/off of a thermostat?

Thank you for the input!
