    Why don't we try to replace the whole array with one or more beefy blue leds?

    well how many LD strings were there? 3 or 4 right? could we put some giant LED's that might emulate a string?

    There are plenty of leds that can deal with this current, but they usually run at a lower voltage (array runs at 32V)

    I've also wondered about just throwing a few blue LED"s in place of the diodes. If you used a few blue LED's and made an array of then, you could probably get close to the operating voltage.

    thats why im considering these


    http://cgi.ebay.com/Cold-White-E40-2...item1c1c293016

    or this one

    http://cgi.ebay.com/LED-Light-Board-...item3a67a4cbfd

    though im also thinking of running mine with 3 lasers as well,but only if all the LED systems fail to produce an acceptable image.
    http://cgi.ebay.com/20W-LED-Flood-Ou...item1c1cfc5d6b...this is the only means i can find cartridge based high power leds...in flood lamps..i mean there cheap but its just a pain. ....Could whoever posted the link to the Highpower LED websight a few threads ago,please do so again?

    this one also looks interesting ......http://cgi.ebay.com/BANNER-LEDIA80X8...item27b5913fbb

    i was also thinking of using different filters,tints and coatings at different intensities on those real bright white ones that run at 20-50 watts.to get as close to 445-450 nanometers as possible...most of the blue leds i have ran across just aren't that bright. that one flecom posted the link to is the brightest ive seen so far.

    Many options here http://www.satisled.com/Wholesale-20w300w-led_c22

    This one http://www.satisled.com/200w-high-po...oice_p164.html even runs on the array voltage!
