Sylvania F40CW/1160MM just shy of 4' where are they used?

Looked on google and cant seem to find any info! Are they slightly longer or shorter than 4foot? Pretty neat.

I too have trouble getting comments on posts. Cant understand if its people just not enjoying the content or the site not being effective enough showing updates.

They are slightly shorter, about the same length as a F48T12 slimline. As for comments it depends on the frequency of visitors and who visits here at a given time.

Interesting find

I've seen bi-pin VHO T12 aquarium lamps in a size like that, but never a normal 40w lamp

Colored Fluorescent's such as F40T12 Red or Green or Blue are awesome...

Probably plunger sockets..I have some for F40t12 lamps that fit into a slimline or HO brackets would be interested to see if these lamps fit

I've never heard of such a lamp. Any turret I've came across used standard length F40's.

Keep government out of the lighting industry.

Hmm yeah my turret and Western Electric lights with plunger sockets use normal lamps. Perhaps these are "conversion lamps" to convert from T12HO to standard output T12? I suspect that might have been a practice in the 70s and 80s when electricity rates skyrocketed, but cool lamp either way.

Please check out my newly-updated website! McCann Lighting Company is where my street light collection is displayed in detail.

It's 2.331 inches shy of 48". Quite hard to find!

Coming back to this post, seeing at there are some HO lamps that the plastic adaptor can come off of exposing normal pins, perhaps one of those adaptors can go on this tube allowing it to fit into a HO fixture, I want to remember the name of the adaptor, its the thing that on some lamps its put over the pins and its black and intended for plunger sockets,,

@Lightingguy1994:
Interesting thought on RDC caps ... Length-wize, that should work out just about right!

F40 Metric just saw some on Craigslist the other day. The ones I saw were made by philips and the post was from Canada. Not sure if these are common there or not but I have not seen one in person and I am not too far from Canada.
