They say that if you time travel you shouldn't change the past. But surely it couldn't hurt to vigorously point out the "minimum 15mm clearance" part of the installation instructions to the installer of the Osram Linestra (and Philips Philinea) style light fittings. Especially for the "double prong" version. Because in a future where the holder is installed flush to the back wall, it is impossible to remove the lightbulb without breaking it. Due to the force required to pull each end free from its socket, the difficulty of getting a good enough grip on the tube at each end to pull both ends evenly without any space behind, and the inevitable result on a long thin tube of one end coming dramatically free and the other end staying in place.

Breaking the first one attempting to get it out and try the working tube (at least when I started attempting to remove it) in the light fitting which wasn't working was rather annoying. Bad words were said. Especially when I thought it was a fluroescent tube, adding more risks to broken tubes. (It turns out they're actually a special design of incandescent bulb, so the main risk is broken glass rather than mercury.)

Breaking the second one -- the formerly working tube I was trying in the known good socket, in the absence of being able to do the converse due to the first breakage -- was almost expected, but still irritating. Yet more tiny bits of broken glass to sweep up. (If you take a 30cm long tube and pivot all of it about one fixed end, it shatters into many, many pieces.) And another prong to remove from the socket with pliers. After pulling the "lights" fuse. Again.

In the future where the holder is installed with the recommended clearance this doesn't happen. You just need to follow the model of the other two identical sockets in the house. They have more than 15mm of clearance, and are fairly easily serviced.

Choose a safer future.

PS: A kitchen extractor fan without an external vent isn't especially effective. Just saying.
