Most Edison Screw Lampholders now have a safety feature that means once put together they cannot be easily undone. This is to ensure you don’t unscrew the lamp holder when changing the bulb and give yourself a nasty electric shock! But not ideal if you need to unscrew the lampholder and put it back together again.
The answer is YES, with the help of a screwdriver, a little persistence (and some patience) these ‘locked’ Edison Screw bulb holders CAN be ‘unlocked’, though explaining ‘how’ to do this over the telephone is not so easy so we have created a short video found below to show exactly how this can be done :)

Wired up a lampholder; found that it lighted up well then after a week the light went out; no fuse was tripped; of course because the holder was ‘unlokable’ it was impossible to investigate the fault. tried the utube video to unlock an identical lampholder but tried as I may could not unlock.
It seems a very curious safety feature since once tightened up there is no was that unscewing the lamp would open it.
The safety feature on this lamp holder is because it takes a screw in lamp/bulb so theoretically the fitting could be unscrewed when the bulb is changed (All modern ES lampholders have to have this or a similar safety feature). Please just return us the lamp holder so we can look up your order when it comes back here & we will send a replacement out. Apologies for any inconvenience this has caused. Our return service is explained on our website Customer Information/Returns and Refunds FAQ’s and the faulty goods FAQ can be found here.
