60W tungsten lamp gives out about 830 lumens.

Useful : 710 lm, in rough agreement with the view of Waitrose, *AFAIR*. Pa ge noted; thanks.
H'mmm ... possibly your supply voltage is at the higher end of the allowed range ... see ! Thanks.
Yes, the biggest annoyance are those strip lights with long supported filaments. They seem to be almost impossible to get now, So as I have two display cabinets that use them, I have basically put them in series so the golden light apparently suits the crystal in the cabinets and the bulbs never blow. They used to blow every couple of months when running flat out. brian
Needed a 5W BC CFL.
Looked on eBay.
£4.99 *each*!!! Jesus. I think I'll switch back to GLS bulbs.
only £2.50 + vat (= £3) at TLC, but perhaps you were looking at dimmable one.

They were 25p for quite a long time. You could also pay several times that and get bulbs of identical lifetime, reliability, etc. It always puzzled me why so many did.

My bulk buy (well only about 50 or so) of Tesco bulbs before the "ban" are lasting an average of about 100 hours each. Some blew after a few hours.
