Did you ever hear of a Dubai lamp?
Old fluorescent light - do they have starters?

LED lamps seem to be generally run with too much current to last. You can try it with a humble little 5p led, turn the current up then it runs really bright, then fairly slowly, burns out.
With some type you can get to the driver circuit and change a resistor (see youtube) . Run them with 30% less current and they go 100x longer, sorta thing.
In other words, it's bloody annoying. They could put two leds in instead of one for a few pence more.
There's a long way to go in LED house ligting. Better CRI (spectrum) is so much nicer, you get proper colours. I've used them for photos. A bit more expensive, but not crippling. Can't find many in BC or ES mounts.

Philips make some really long lasting ones, but I've always wondered "where Dubai them from in this country?"
Dubai lamps : extra LEDs that are run at lower power so they last longer:
I believe the tubes last longer than the LED's which seem to fail regularly.

There is that aspect to it
You could maintain the old fluorescent fitting with a new tube and starter
Starter holder overheating and end-caps were troublesome with them though

Things have moved on, 6th July 2023 not that long ago, but still we are seeing the price of LED lamps dropping so today I can get one for £5, often a lot less.
The problem is the light does not come out in the same direction to the old lamps, be it tungsten or fluorescent, so we have to be careful what we select.
I have two carriage lamps outside, one is integral and one has a bulb, it seems the integral one is far the better of the two, but it is really because the integral has the light at the top shinning down, and the bulb has the light at the bottom and shines up, use of a reflector has improved the bulb one.
But it seems although the LED bulb emits the light in a different direction, carriage lamp manufactories have not changed their design to suit.
