Bulb wattage for chandelier light?

[SUNRAY]

Undoubtedly, but anything remotely approaching 22W of any sort of LED sounds (to me) to be an awful lot to illuminate things just a few inches away - but maybe I haven't 'lived'

15W/metre is quite the norm these days for LED strip and some of the more dense 'pro' versions I assume the power goes up acordingly.

That seems like an awful lot, which probably equates to well over 100W incandescents per metre.

I wasn't doubting what you said, but it remains the case that the 'equivalent' of 100W/metre of incandescent lighting seems to be an awful lot to me - if one put one of those strips all the way around an average room, one would probably end up with in excvess of the equivalent of 1 kW of incandescent lighting!

Don’t forget colour temperature has a big impact on perceived brightness

a 5w 2700k warm white build will seem much duller than a 5w 5000k cool white bulb.

Yes, I realise that, but the figures we are talking about seem so 'extreme' (e.g. 180W of LED strip {at 15W/m} to go all around the edge of a 3m x 3m room) that they surely can't be explained by just that? Let's face it, such a room may well have been lit by just 100W (or maybe 2 x 60W) incandescents in the past.

Assuming a 4m square room 'twould be 240W. We have 8 25W candle bulbs; 5 in chandelier + 3 wall lights and rarely do we have all on.

Quite so. When I said "over 1kW', I was actually thinking ('modestly') of a 3m x 3m room - but, as you say, for 4m x 4m and 15W/m (LED) that would amount to 240W of LED, probably 'equivalent' to nearly 2 kW of incandescents (a fair bit more than the capacity of a 6A lighting circuit!) - rather different from your 200W

I still don't really get it!

Would 40-watt LED bulbs be suitable to use in the chandelier or would the wattage be too high?

As others have pointed out, 40w LED's, even if you could buy 40w candles, would be far too bright. For a similar light output, dived by 10, so around 3w or 4w LED.

The 40w rating of the fitting is one of protecting the fitting from heat damage, the waste heat from tungsten lamps. Whilst LED's emit much less heat, a problem they do suffer from, is inadequate cooling, in enclosed lighting fittings, designed for tungsten lamps - and so something to be aware of.

I'm finding fittings are often listed with 2 values now; such as 40W & 5W LED.

For a chandelier light, sticking with 40W or 60W bulbs is a safe bet to ensure you don't overload the fixture or make the room too bright. Make sure to check the chandelier’s maximum wattage rating first. If you prefer energy efficiency and less heat, consider LED bulbs with a similar light output to the wattage you need. They come in a variety of brightness levels and styles that can mimic traditional incandescent bulbs. Best wishes.

1) Date 8 Mar 2023, so one would hope, sorted.
2) Overloading with 40W or 60W or even 150W, which is about the largest domestic bulb one could have years ago got, is unlikely.
3) It is in the UK near impossible to get anything other than LED bulbs, so unlikely anyone could fit tungsten even if they wanted to.

So one wonders what is going on in the USA if you can still get tungsten bulbs? Here over the pond, our problem is LED lamps aim light away from the base, this means some lights are not giving the spread one got with tungsten, aimed at a ceiling it defuses the light and reflects it to light corners etc. but aimed at the floor, which is often dark, the light is absorbed.

Which raises the question, why do people use GU10 down lights? However, the problem here is down to what heat a shade can take, the larger the tungsten lamp, the more heat it produces, but we are looking at the ratio of heat to light, so a LED produces more light and less heat, so if rated at 40 watt tungsten likely it will take 100 watt LED without a problem, however one would need to wear sunglasses.
