Anyone got any experience with converting laptop backlights from CCFL to LED?

I've recently bought 3 Dell E5400's spares/repair and hope to repair and dedicate at least one of them for car diagnostics use by myself. All of them have problems and came with parts missing, two have dead screens and one has a working screen but it is marred by pink horizontal lines across the bottom In the taskbar area. All of them boot to bios on an external screen.

I'm looking at buying some cheap LED backlight conversion kits from China, the screens are WXGA on the E5400 and I believe that the CCFL length is 307mm but the nearest LED strip that I've seen so far is 310mm. The strip can be cut to shorten it but in groups of 3 LEDs only, would this leave it too short for ease of use?

I accept that post conversion the backlighting may be a little different to OEM but I'm hoping for increased longevity and durability in what will be a working web-free environment that will be different to the norm for use in a home. Thanks in advance for any help and thoughts.

Edit Update 1: I've had a look at the inverter boards on 2 of the laptops and they have different types of screen connectors, one has a 2-pin socket and the other a ribbon connector. The number 0487GT on the board with the ribbon connector identifies it as an LED inverter so good news, an LED backlight is already present on at least one of the laptops. I've just been on ebay and I've managed to order a used but working replacement 0487GT, fingers crossed that it will fix the dead screen on 1 of the laptops.

Edit Update 2: Laptop model typo E500 corrected to E5400.
