BYOI - Bring you own insulator.
This attractive, contemporary lamp base fits the following glass insulators:

Hemingray - 16 - CD 122 (the number is on the front of the insulator)
Hemingray - 17 - CD 122 (the number is on the front of the insulator)
Armstrong's - №2

This base will not work for Hemingray №16 (CD 121)

It embraces a unique, modern, industrial, techno look, perfect for your loft or mid-century eclectic décor.
This gorgeous lamp would also be a great accessory for your Lanai or 4 Season porch. And it makes a great addition to any man cave.
The base light uses a 2-watt LED light bulb, available in 4 different LED colors.
It has a 6' black cord with an in cord on / off switch.

Note:

I recommend green LEDs for Turquoise (green) and blue LEDs for aqua insulators
The base does not include a LED light bulb. LED light bulbs are available for an extra fee.
This is a base only and does not include a glass insulator
