Been looking into a few different types of heat for my door finishing at work. I saw there are also infared heaters that run off propane. Hmmm?
The thing about anything electric, less input, less output, but gotta live with your power supply..
For my little work shop I hardly got room for anything else on the floor. I got a bathroom 6 light strip fixture I may try hanging from a pocket door track setup that I can slide & lower slightly. I'm debating about getting more of the red 250 watt Philips bulbs or see what's still available in regular floods that isn't cfl or led as Barry suggested.
