Been going to get some strips for a while.....
Just a big question as to what's actually in the strip.
Some have current limiting resistors, not good, just a cheap & dirty way of controlling the current & wasting a fair bit of power.
Some use current limiting power supplies & these ones are almost 95% efficient.
Easy to pick one you get you eyes on them in some cases, not so easy in others.
If there's any sort of temperature in either the strip or the controller it's probably just using resistors to limit current.
Actually tried a couple of COB panel leds in a few
places, like interior lights, including the rear one in the Pajero.
They seemed to work fine & with excellent light, simple, bit of double sided tape was supplied to attach them.
Then I notice the one in the rear of the Pajero had failed. Thought there goes 2 bucks & wasn't too concerned until I removed it.
Discovered the negative wire had come off due to the soldered connection melting.
The double sided tape was also all melted up & brown.
Played with a few others I had & found it didn't take long for the things to heat up to in excess of 100°C, (The wet finger
test).
They are great panels, but need the resistor removing & a proper current supply used in its place.
