Great reviews on these 60W equivalent bulbs which produce a very good quality light (subjectively much brighter than a 60W filament). On offer at £7.99 for 5 bulbs (£2 off).
This is for the 9W warm white on a BC fitting. Also available in cool white and/or on ES fittings at the same offer price. Specified as 806 lumen with a colour temperature of 2700K, however they seem to have a slightly better quality light than a tungsten bulb and I'd wager most people would say they're noticeably brighter than 60W but still a pleasant warm white tungsten-like colour. Specified for 15,000 hours and with a 3 year warranty.
