Can't find it on the website, but probably are somewhere, bought these in store....
Tesco are doing a buy-one-get-one-free on their energy saving light bulbs.
Included in this offer is a replacement for the halogen GU10's that are so ubiquitous these days.
It is a 7W (35W equivalent) CFL bulb, GE branded I think.
It kicks out a not-unreasonable amount of light, certainly not the same as a 50W halogen, but then it doesn't claim to be. Also won't be the same quality as say Megaman's, but at £2.50 each, certainly cheap and good enough for our hall.
About time the price of these came down.
