We bought a bulb for testing color. It is an
Aeon Labs Aeotec Z-Wave LED Light Bulb, Gen5.
It worked. We can make it do color. But we also took a look inside and it was pretty interesting.
The outside ring has 15 diodes and produces only white light, which they call "cool light".
Inside that ring are 4 more diodes that produce red, green, or blue (RGB). It turns out that "warm light" just has a little red added.
