Downlighters

With three halogen downlighters in a 6ft x 6ft ensuite, what power should they be? Would three 20W be enough?

To get the equivalent between incandescent and halogen, multiply the halogen wattage by 1.15. Thus your three 20w halogens adding up to 60w will be the equivalent of a 69w incandescent. For that space, they should be bright enough. The next up halogens at 40w each, you might need sunglasses!

Many thanks, heathfield. That's just as I thought, so now I can tell my know-all son to get knotted!

It's a matter of taste. As it is such a small room you may be ok, but I think I'd prefer a forth light somewhere. Maybe 'suck it and see'. When I did my kitchen I thought 6 would be enough, once they were installed I thought them too dim. But one gets used to them and they seem adequate now. Not really as bright as a kitchen should be, but okish.

Thanks, OG. I have downlighters in my kitchen but have not checked their power. With six of them it's bright enough - don't want it to show up the grime!

For safety from the heat point of view and economy I'd recommend replacing halogen with LED lamps.
We have 3 x 4 watt LEDs in a bathroom of the same size and it's fine.
They're expensive to buy but very cheap to run.
