NOS Killerwatt 2x 20w circline unit from '77!

NOS Killerwatt 2x 20w circline unit from '77!

Click to view full size image

What a find, one of the very first screw in fluorescent retrofit lamps (not counting the screw in F15T8 adapters from the 40s) sold in the USA. It is all NOS, made by Killerwatt of Los Angeles, CA. The original lamps supplied with the adapter are here, they are GE FC6T9/WWs dated 3/77. The adapter also features two replaceable starters. Good stuff that lasts on and on! The true "compact fluorescent" lamps using all new designs like the Westinghouse Econ-Nova and Philips SL series would not be available for another 3-4 years.

Very nice Duel circline adaptor! BTW I find it hard to find 20w circline tubes, but lucky my restore is loaded with them in CW.

No LED gadgets, spins too slowly.  Gotta  love preheat and MV. let the lights keep my meter spinning.

Very nice, a simple & reliable design that could be recreated at home with a few bits and pieces . The smallest circlines we have here are the 22w FC9(?), not counting those rubbish T5 things used in cheapo angle-poise magnifying lamps.

Traffic signals & street lighting engineer. Please bring SOX/LPS back Downunder!!

Sure, go for it! This is very easy to make. This model i have is already heavy enough! By the way i also have a single lamp version of this, with an NOS GE 20w WWX.

I wonder where we could get the Edison screw base? I have starter sockets and the leads for the tube connection. I could fabricate the tube mounts. I have several each of 20, 22, 32 and 40 watt circline tubes. A 22/32 version would be cool too. Preheat, of course!

Very cool and different! Never thought of an adapter taking not one but TWO circlines!

Long live the great old 20th century quality in electrical & lighting products!

You lucky son of a gun. These have not been made since the early 1980s and by what I have found, Killerwatt Corp was put out of business in a lawsuit in 1983.

Interesting, so Killerwatt and their lamps did not make it to the mid 1980s. As I said, i was lucky to have found this lamp at a ReStore. Oddly the outer box was missing, but part of the inner carton, along with the instruction paper, was still with the lamp. It showed a picture of a woman setting up a table lamp for the Killerwatt circline adapter, looks very 70s! I also have since found another Killerwatt circline, a 22w single lamp unit, used condition, also from 1977 with its original GE warm white lamp. That lamp came with the older ceramic base!
