LED signage COB module teardown

A close look at a COB-style LED module as used for signage illumination. I chose blue so we would be able to see the bare LED chips.

These low voltage modules are used as an alternative to neon and fluorescent tubes inside signage. They have the huge advantages of being relatively safe to install and being very flexible about how they can be placed inside channel letters.

As always with LED strips and modules, it makes sense to slightly under-run them for longer life at the cost of slightly reduced intensity.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
