ScrewFix are pretty good on price, check them out and make an account (if you don't have one). They order like Argos.

On their website Q&A for that tube it says this...

Hi, these tubes are designed to be a direct replacement on magnetic ballasts. The tube comes with a 'dummy' starter that is used in place of the old one.

@Snowy I have an old RCA LCD TV (around 45" or so) that I'm planning on doing just that with. The power supply went out on the TV, so it no longer turns on, but I should be able to find a generic power adapter that I can use to make the light panel work. I may mount it on the ceiling above the computer once I get it all working.

The give away on whether it's fluorescent or LED back lit LCD is how deep the screen is. An inch or less LED, 2 inches or more fluorescent.

  I just ran across an article for motion sensing wireless led lights, I always found the motion sensing lights interesting and thought they would be useful but never put any in.  Its pretty easy to just flick a switch.  Not that sure about wireless, having to change a battery when you have to go into a room.
