RGB LEDs
Due to the tube’s opaque spacer, and also semi opaque base of
many of the tubes that fit this kit, RGB lighting is problematic, in
fact you may not wish to use RGB tube lighting at all, in which case
simply don’t solder the RGB LEDs.
If you wish to RGB backlight the tubes, this is the best method.
First, coat each LED with black nail varnish. Use a thick coating,
but not so much that it drips. Leave each LED to dry for 24 hours.
You can use the black foam square as a jig to hold the LEDs as you
paint them.
Once dry, scrape a thin band off using a sharp knife. Note the
position of the longer 2 pins.
