I bought a kit off ebay that came with an SMD 5050 RGB LED strip, an IR controller and a 3A PSU. Long story short, I have a second srip on its own and instead of buying the same PSU, I'm wondering if I can use a higher amperage PSU (5A) to power the strip so it can be brigher essentially. The ebay item is here.
What I'm sceptic about is that (while not listed on the ebay page specifically) the strip is rated for 2A each colour, and the IR controller is also rated for <2A each colour.
In my mind this makes sense as when using all colours, the 5A is distributed across the three colours using ~1.6A each. Sweet. But what happens when I run just a single colour, say blue? Does the 5A all go into that single colour potentially frying stuff or does the excess get grounded or is it even pulled from the wall at all?
