First, here is a single element cleaned of its yellow phosphors, showing 8 tiny LED chips wired in series. This block is about 2.5 mm square.

Here is a different element, partially disassembled, this one weakly powered with about 4 µA drive current from a bench power supply. The dark blob below the center two elements is the power delivery post that appears at the top of the preceding picture, here seen mostly buried in yellow phosphor. You can clearly see the distinction between the blue-emitting LED elements and the surrounding phosphors that turn the intense blue into something closer to a normal white balance.

Two elements, intact, dimmed with a wall dimmer.

Here is an overview of the bulb with and without its shell. Notice that not all the elements have the same color balance. As far as I can tell this is random variation, probably due to differences in thickness of the phosphor layer. Again the bulb was dimmed way down to show some context; at full brightness all that shows is a band of light across the bulb. On the right side you can see half of the 10 light-emitting elements, again all wired in series, making a total of 80 LED junctions at roughly 230 volts DC when the light is powered.

Here's the way the manufacturer wants you to think about this technological marvel.
