Hi folks and thanks for reading. I want to make an edge lit polycarbonate nightlight for my new grandson's nursery and the best way would be to use led tape and a suitable driver or psu. Drivers tend to be expensive (I might plan to sell some of these if the first goes okay on our local market, PAT tested etc) so I found a suitable wall wart off ebay for about £3.
However, I want to maximise the life of the led's and I have read about using a resistor in line to tailor the applied current for maximum lifespan but don't know how to go about calculating it. The PSU I was looking at outputs 12v 1A and the strip would probably be for example 10 led's long.
Could someone help me out with the math's please? I'm good with maths but don't know where to start with this one.
Many thanks, Lol
