There has to be an easier way to get 7 watt, SES cap, compact fluorescent light bulbs than to get in the car and drive all the way to IKEA in Croydon. B&Q don’t stock them. My local electrical wholesaler wants ¬£20 each for them. Online resources either only offer them in packs of 10 (I only want two!) or don’t offer the SES variant, just ES or BC. guh. Suggestions anyone?
