What do I look for? - Replacement light question.

Rusty190

Looking for guidance please. 
I have an ancient, though functioning, strip light with 2 long fluorescent bulbs in it and a plastic "shade" to cover the bulbs. 
1 of the bulbs is on its way out - constantly flickering and going dim.
A quick online search tells me these sort of bulbs are no longer available and I should be looking at LED lights. 
Is there such a thing as a similar style LED light ie. one with 2 long bulbs, bright, bulbs "covered" and bulbs replaceable?
It's for a kitchen. 
Thank you.

Why do you want to replace the whole fitting when you can replace the tube(s)?

Read the instructions - some LED tubes require minor changes in the light fitting.

@grumpy_codger, short answer is, I don't.
But, do those LED 's you linked to, not require other "tinkering"/wiring stuff to be done? - or do they just fit into the old unit as they are? 
Oops - can see you' ve already answered that. Thanks.
