LED Tubes.

[tanto]

Hi, not been on here for a good few years so sorry if this has been discussed previously.
Bought a new Energizer LED 5ft tube to replace the knackered fluorescent tube in our utility today. However the new tube is not a very secure fit in the end holders. It does work ( also replaced the old starter with the new “fuse”. End fittings are the same. Slightest touch to the fitting when trying to put the diffuser cover back on dislodges the tube and the light goes off. It appears the new LED tubes are around 2 - 3 mm shorter than old fluorescent tubes therefore not making a great contact. I went back out, bought another LED tube (STATUS brand) ,thinking I maybe had a dodgy first tube. Turns out the 2nd one is the same. Anyone came across this issue , not much difference in the length but enough to be an issue.
Looks like I will just need to replace the whole unit now for safety and piece of mind.
Thanks,
Dave.

Perhaps the end caps have lost their springiness

A wrap of electrical tape starting on the tube, round the end cap and finishing on the other side of the tube should secure it enough to get the cover back on, where it will then work in disturbed. They don't get hot (and I wouldn't worry about putting some plastic tape on a plastic bulb cover)
