I replaced the internal spotlights in the van a few years ago but as we only ever used one of the three strip lights (the one above the kitchen hob) I didn’t bother doing those , but that strip light has packed in so I’m looking to put led in instead. Has anyone done this and can recommend a source for the led replacement, picture attached. The original tube is Sylvania Flexline FHE21w/T5/830 (am assuming 830 cm is the length). Cheers
