For 24v LEDs, I use Searolf. The products are excellent, and the back-up service without fault. Honourably changed a navigation light bulb two years out of warrantee, without being asked to.
I put warm white 24v LED strips in all the galley cupboard, from https://www.brightlightz.co.uk I found them very helpful and able to answer queries. Tip - order once and then use the 10% discount code which comes in the bag!
