Three-way bulb's brightness levels are out of sequence
17-Nov-15:  Received a response from GE Lighting:
This product (LED22A50/150) was designed to have the highest light setting in the middle position.

In other words, the order of the light settings is low(50), high(150) and medium(100). 

This was done so that if you use the bulb in a single wattage socket it will light on the highest light setting.

Wonderful!  So it works in a single wattage socket AND doesn’t behave like a standard three-way bulb!
