I'm currently in the middle of a lighting project and am new to the LED game - I've read about as much as I can find about LED brightness but it's just not going in anymore!! I am lighting a plastic rod bent into a semi circle using LED's at either end and need to be able to see it in the daylight - I have considered using a CCFL but these are
a) too brittle
b) don't come in the size that I need
I've been using various LED's over the last few weeks with different outputs and haven't really come up with a satisfactory light output. So far I've tried 5mm 20kmcd, 5mm 55kmcd and 5mm 100kmcd. I've also tried using a luxeon 1watt 40lumen led fitted with a reflector to focus the output in a lightbox and feeding the light into the ring at either end with an end emitting 6mm fibre optic cable. I have seen some 8mm white LED's advertised as outputting 280kmcd and some more that claim 60lumens?!?
