I will go for a bulb then, one built for 240V. I guess that can be done safely.

If I have the flexibility of even doing one that is 1000W and can plug it in and move it around and raise it then that's great.

A 1kW bulb would be blinding, and a danger in itself. It's also a different animal to a bowl heater. What exactly are you trying to achieve?

Infra red bulbs produce less light.

I've seen somebody use a greenhouse heater to heat a garage. It wasn't blinding.

If a 1000W infra red bulb would be dangerous and blinding then a couple of 300W infra red bulbs would be fine. I want to mount them and be able to move them and raise them up and down and plug them in.

get the heater and stick a 32 uF capacitor in series. It will work

I'm pretty sure we were talking about heat lamps, not IR bulbs.

Without knowing the details I would not assume it safe. Your not being aware of the safety issues only leads me further in that direction.

Thanks Peter, that kind of thing, an infra red bulb, looks good, I just need a bulb holder for it with a plug. I don't want to drill a hole in the wall so something like a lamp that could take a bulb like that would help. But the wattage seems low for my purposes.. I want to heat a small bathroom with it.

the most common heat lamps are 275W filament lamps, they've white light rather than IR

I guess a 275w lamp would be very slow to heat a bathroom

https://www.amazon.co.uk/FoxHunter-I.../dp/B06XHH523H

I see these things advertised as being to heat or pets that stand near it, or for physiotherapy.

I want it to be a heater whose bulb or light source is very accessible so I can clean it. So it doesn't smell.

The main issues with heat lamps & IR heaters a
tip over, solved with a switch on the underside
guarding
concentration of heat leading to injury or fire. Ideally you want a nonconcentrated source that doesn't focus - bowl heaters fail on both those points as well as tip-over risk & on stability. Heat concentration is ok in situations where the lamp is fixed in place in a position that can't cause anything to get too hot, hence one reason why IR heating is normally placed above head height.
And if you roll your own the whole thing needs to be up to the temps involved, which can be fairly severe.

Now that you've said what you want the heater for, the recommendations are
different. Your first post was about how to drive a 120V bowl heater. That
claimed to be much better than other heaters because of its low wattage. It
is only better for heating one spot because all the heat is concentrated by
the parabolic reflector.

For heating your small bathroom you need more wattage and more distributed
heat. I have a 2KW fan heater in my bathroom to warm myself, but it's not
enough to heat the whole room much and is probably illegal because it's too
near a wet area, even though it's double-insulated in a plastic housing.
Perhaps a paraffin convector heater would obviate any electrical dangers. Or
maybe a heated towel rail.

Back in the 50s and 60s it became popular to fit what were
marketed as "Heat Light" lamps in bathrooms, because they quickly
gave a feeling of warmth. The small ads often used to feature
them.

When the original bulbs failed, cheap replacements were often
bought that were not designed to cope with condensation,
resulting in shattered glass - pretty nasty in a bathroom.

I recall having a large roll top desk up in the attic where I did
my homework, and used a reflector heater similar to the one you
have looked at. In the end a fan heater blowing into the kneehole
was a safer replacement.

Yes - and as were proper infra red heaters. As a kid we had one. The only
heat in the bathroom. In the NE of Scotland. Just about useless.

FWIW the point of bowl heaters was to warm someone sitting in a chair. Because they focussed the heat in one direction they could be low wattage, making them far more affordable than other types.

We've used infra red heaters on a film location where it can be impossible
to heat a drafty old warehouse, etc with space heaters.

Fine to warm your hands etc when fully clothed, but absolutely useless in
a bathroom when having a bath.

not at all, a 1kW IR heater provides 1kW of heat, enough for a small bathroom. Some are lower power of course.

It's the absence of evaporative cooling from the forced convection of a
fan heater that makes the 'Infra red' heater a better fit for bathroom
use. Even when the draught of air from the fan heater is very warm, the
evaporative effect can still chill wet skin unless the air in the
bathroom is virtually 100% humid.
