Causing hermies?

Will something that emits infrared light (not visible to the human eye) cause your plants to go hermie if it is used as a heat source during the dark cycle of flowering?

I'm talking about these to be exact:

No visible light is given off, only infrared light and heat. I'm looking for a cheap solution to keep my little grow box warm in the winter months so any other suggestions are appreciated.

The bulb description says that it doesn't emit light. You should be ok.

id get a little space heater.

I would except I already have the smallest one that I could find and it still draws 11 amps. That wouldn't be a huge issue except my grow draws power from my living room which is pulling 8 amps itself and 12 with my grow lights on. Granted the heater would only be for the dark cycle, but still 19 amps is way too much for a 15 amp circuit.
