Brilliant Little Package

I've just installed these gems onto adhesive copper foil tape to light the interior of a model aircraft carrier hangar deck. I needed something very small and unobtrusive. These SM LEDs were just what was needed. Their wide angle illumination would reduce hot spots and give an even lighting.

You need to take care to hand solder them since you must leave a small, 1mm gap for the space between the anode and cathode contacts on the LED's bottom. You must then lightly tin the copper foil, place and hold the LED with a tweezer and then heat the copper next to the LED on each side to melt the solder and make the connection. Their brightness is something to be seen and they will really light up the inside. I'm going to use this method on many other model structures for the same reason, lots of light without obtrusive bulbs in the way, no heat and very low power requirements. Frankly, if I didn't understand how LEDs actually work I would think they're magic.
