Needed a bulb for a bedside light today, so popped in to the local excellent hardware-and-all-sorts shop.
Good ol' fashioned 40w filament bulb. 99p Halogen 28w-bright-as-35w. £2.99
WTF is the point of a "low energy" bulb that only saves 20% of the juice?
Extended life? Mebbe. Three times? Unlikely.
