Special code
When measured in lumens
E = Brightness group
F = Brightness sub-group (default
0 means no sub-group)
When measured in milliwatts
F = Brightness group

In order to minimize the perceived luminous flux variation
among white lamps from the same reel, Cree bins to
tighter luminous flux sub-groups. These sub-groups are
defined below.
