IR-lamp or regular bulb?

I’ve been wondering a while about the reason they do ceramic plate to IR lamps.
I agree that even common light bulbs are (and make the surrounding lamp) hot, so what’s the difference?

The only answer I came to is that IR lamps are often much more powerful than usual light bulbs: for example, commercial IR lamps from Philips if I remember well are ~300W, while a powerful light lamp is ‘only’ 150W.
Maybe for a light 300W lamp they’d do ceramic coating too.

I imagine that the red coating is more to diffuse the white light which would be very irritating if the lamp was used over a long period.

The 100 watt IR lamap is quite small. Just slightly larger than a 100 watt desk lamp ( which would probably be too strong anyway)

It may be that the ceramic coating is a requirement for safety reasons. I expect Google has the answer somewhere.

So what exactly are the problems involving the testicles? Is it the extended heat, or can this cause cancer?

The heat produced by the IR lamp in the testicles will kill the sperm and mess up the testosterone produced there.

That is why they ride up and down - To control the temperature inside the scrotum.

But in the well known Cusses Law. If you tried to kill the little ones with heat so you could have ‘safe sex’. The the little so and so’s would survive.
