Bulbs, wattage, heat and maximum ratings

Bert Coules · 2012-09-25T22:26:09+00:00

I need wall lights with individual switches for the bungalow I'm doing up. Wickes have these: use SES globe bulbs and carry the message "maximum wattage 40W" but just how critical is that warning? Is it a question of heat output? Wickes stock low-energy bulbs marked as equivalent to 35W and others rated as equal to 50W: is there really so much difference between the two that using the higher-rated ones could actually be dangerous?It's not clear from the photo of the unit but the curved glass shade is open top and bottom and also stands clear of the wall on either vertical edge. The bulb itself is not enclosed and I would have thought that there's a good deal of air circulation around it.Many thanks.

But they're taking all the thorium for nuclear reactors. :-)

Yes, then we'd have some decent light.

Ban all CFLs forthwith, and bring back frosted envelope incandescents ...

I know that really. :-)

And that they don't actually use thorium in mantles any more.
