Houston…we have a problem.
Finishing off some details and when I turned on the lights most of the Blue was missing – bugger!

Tested again this morning to confirm and the RGB LED strip is indeed faulty, the controller itself is OK.
What happened ???…I don’t know but it’s fortunate I ordered two sets of lights. I’ll have a look to see if I can repair the faulty strip at a later date.

Back to square one and remove the faulty LED strip lights.

Second time around and doing a neater job, even replacing the blocks with ones that have a gentler curve and making sure the LED’s don’t fall on the peak of the blocks.
