Anyone have any experience with 'Exo Terra Ceramic Heaters'?

With winter right around the corner I'm trying to find something that is fairly cheap to heat my plants with while the lights are off. I have a small portable electric heater but that tiny thing draws 12 amps by itself. I don't have anywhere near that much free space on my breaker in my grow room. I could run extension cords, but my wife would flip her lid if cords were winding through the house like that. With that said, I came across these little things and wondered if anyone has had any experience with them before. The reviews on Amazon say they only last a few months, but if that's the only issue then that's fine by me. Here's some info on it.

60-250 Watts; Ceramic Heat Emitter
Emits a natural "sun-like" infrared heat
No light emitted, does not disturb normal day or night periods
Solid ceramic element, suitable for humid environments
Promotes health and healing; 1 year warranty

But then it goes on to say:

Exo Terra Heat Wave Lamp Ceramic Heat Emitter has a broader sun-like spectrum of infrared radiation than incandescent lighting and doesn't emit visible light.

I know that infrared is heat, but is the infrared spectrum something that would cause a flowering plant to hermie?

Bumping this bad boy.

Yeah man. I use those. One will keep my cab 2x4x7 about 20° warmer.
Helps control Powdery Mildew too.

Awsome, but just to confirm - you use them inside your grow room during the dark cycle while flowering without causing hermies?

Yeah sure, Actually I bought two of them and run them on a timer during my indoor winter grows and haven't experienced hermies doing it. Done it for a couple years now. I'm lookin on craigslist for a couple old waterbed heaters for my greenhouse this winter. I heated a hydro setup last year with a rope light. Yeah, I tried a few things.

Here is a shot of my cab, you can see them under the hydro tub.





I exhaust out the top so it draws the heat from underneath.
