New Project looming: very bright LEDs

Ed,

This page addresses resistor selection. Hope it is helpful.

Any 12v dc adapter with a minimum of 100ma will work. I'll look around for old wall warts and cut and splice as needed.

I'll call Artisan, but does anyone know if the LEDs Artisan sells run off a 12v power supply?

Also, The gooseneck halogen lamps Artisan sells have a magnetic transformer and can take an MR11 LED bulb. I've ordered one of these and will report its effectiveness. From what I've read, nearly all devices with magnetic transformers can power LEDs. Most, if not all, electronic transformers pose a problem.

I knew the knowledge gained fiddling with transformers would pay off in some additional way down the road.

Some people have a difficult time dealing windfalls of enormous wealth that would allow them never to have to work again for a paycheck. I nominate myself as someone who deserves a lifetime of free time. Give me some bare wires, a soldering iron, some current, and a few calories a day and I am as happy as one can be.

I just got my electric toys today. It's too soon for a full report but things look good. While these lights are brighter than most of what's currently available, I was hoping they'd be a bit brighter. But perhaps brighter LEDs will create a heat issue.

Ed, I can see this happening:

...MESSAGE INTERCEPT....

-FLASH PRIORITY-

-TO DHS, CIA, NSA, FBI

-ASTRONAUTS ABOARD ISS HAVE REPORTED STRANGE LUMINOCITY FROM UNEXPLAINED

-SOURCE. DESCRIBED AS INCREDIBLY BRIGHT REGION AT GROUND LEVEL.

-NORAD CONFIRMS: NO MISSLE LAUNCH BLOOM, NO RADAR TRACK

-SCIENTISTS AT NASA AND JPL TO RETASK SATELLITES TO ASSIST IN IDENTIFYING SOURCE

END MESSAGE

When they knock on the door, just tell them you have no idea what they're talking about.
