But both on the box and in the instructions, it says "This lamp uses a
150W max 3-way bulb, do not use an A-19". Now assuming A-19 is a
regular incandescent bulb, this seems quite strange. I've never heard
of not being able to use a 60W or 100W incandescent bulb in a socket
designed for 3-way.

Is an A-19 a regular bulb, or is it the designation for a halogen?
IIRC, halogen bulbs are not 120V, but some lower voltage. Maybe
that's what they're trying to tell you, since most of these lamps DO
use halogens.
