  1. I need to supply a couple of high power LEDs for an application next
    Saturday. Time is short and I will need a local supplier. I've looked at the
    usual suspects (Jaycar, Farnell and RS). RS seems to have the best, most
    economical solution so far. I will entertain others. Here is what I am
    doing:

    * High power blue LED. Dunno about 'Royal Blue' or regular blue.
    * I need to focus the beam as much as possible. It's for a small mirror
    ball.
    I note that Luxeon make 80 Lumen blue LEDs, but the gruntiest one I can
    locate is 30 Lumen.

    Any assistance for a local supplier would be appreciated.
     
  2. Cutter have Cree XPE in Blue and Royal Blue:

    Blue is 40lm @ 350mA, but they can be safely driven at up to 1A if desired.

    Lenses to match:

    They have constant current drivers too.
    This one is good for direct mains connection, LPC-35-700:
