PL Lamp Identifcation

[LewisM]

Hi, does anybody know what the lamp needed for this fitting is?
The fitting doesn't have any space for the retaining tabs that stick out of the side of the most common PL lamps, very odd.

Take the fitting down and have a look inside or on reverse for manufacturers details such as item number. Part number etc. It may even say on the back...

Take the fitting down and replace it with a proper British B22 pendant set.
