Unless you are pressing that bulb to your skin, you are not exposing tissues to red light with an incandescent bulb. It's mostly NIFR, and FIR. There's a reason why redlight therapy devices or anything to do with PBM uses LED's, or laser diodes. They don't produce tonnes of heat. heat/radiation is the enemy of red light exposure, and spectrum based PBM in general
Your skin will react to the NIFR and FIR, but it's not activating the same kind of things or causing the same responses as what happens when you expose your body to pure wavelengths of the redlight spectrum sans heat. Even if you could somehow tolerate being an inch or so away from a chicken broiling lamp or something of that nature, you'd still not be getting a high intensity of redlight either way.
You are already getting plenty of NIFR and FIR from sunlight exposure during the day
