We call that "Alien Autopsy" lighting!
At the Timonium Hamfest, they were selling a couple different type LED
replacement bulbs Two had maybe 30 of the bluish white ones, and were
between 15 and 20 dollars each. The other one was smaller, kind of
like the light you might see in a bathroom fixture, and a whole lot
more attractive - it looked like a normal bulb instead of a conical
pyramid with spikes on it. The nicest thing was that the light color
was darn near that of a tungsten bulb. I agree that those are likely
two LED's in each individual unit, a blue and a yellow one.
