I have a new build house which has these new fangled euro energy saving lights. One lamp went so I bought a new bulb but after putting it in it didn't work so it looks like it's the lamp holder that is the problem (it's not the switch as it switches 2 lights and the other one works fine. I looked on TLC (where I got the bulb from) and can't find a holder. This is the bulb
Thanks
