It's worth considering that a 300W linear halogen lamp will have a
turn on surge that equates very closely to the current draw of a 3KW
electric kettle. Whilst a 20 to 50 watt LED lamp might create a switch
on surge, I rather suspect it won't be quite the magnitude of a 300W
linear halogen lamp.

I very much doubt the LED +PSU has any noticeable power on surge, unless
it's PSU is large magnetic (50Hz) transformer. Don't think there's too
much to worry about

Both CR and smpsu PSUs do have a switch on current surge, but the i squared t is tiny compared to a 300w filament lamp.
