Thanks for the advice. I didn't know that. However, I've got a variable voltage adaptor. so I'll probably set it to 9V, which should keep me under the 12V even taking into account the 25%. Failing that, I might just use a 9v battery and change the design of the arrays to reflect the reduced voltage.

Have you used the LED array wizard ? You can play with your array parameters until you get one that is simple to build. Frank Each of the two arrays I've listed above was created using the array wizard, and I'm satisfied that they will work fine on their own. It's when I put them together that I'm ...

I'm going to attempt to light my PL 1/350 Refit E, and will be using a 12V DC supply with a mixture of 1.8 and 2.8 volt 3mm LEDs, all rated 20mA, broken down as follows: 12 x 1.8V (6 LED x 2 series lines, and 68 Ohm R in each line) 20 x 2.8V (4 LED x 5 series lines and 47 Ohm R per line). I'm not pl...
