Wide-Lite 1000 I’ve never tested it , I’m afraid too
The bulb appears to be burned out,

Back in the summer of 2017 an L&G member posted this fixture being for sale in a Craig’s List ad ,
I was one of the members who responded, I was told whoever shows up 1st gets it ,

With the cord being frayed (not shown) and the bulb appears to be burned out I haven’t looked into plugging it in , Right now I’m trying to figure out where in the house I should hang it - More then likely in my room as I’m getting tired of sleeping with this thing 😜🤪😝

Truthfully, I'd be scared to test it too ! Like with my GE 250w MV from 1958, I'd rather have it as is then risk trying it and having it go POOF! and me go !

You sleep with your lights?

Just messing with ya' !

Yes I sleep with my lights
The old frayed line cord that came with it is somewhere around here , As soon as I locate it I’ll put it back on the fixture, My plans are to keep her original just the way I found it and get this darn thing off my bed and up on the ceiling where it belongs 😂😜

I agree with You I like my stuff all original and don’t really care weather or not it works and really don’t care to find out , I just enjoy rescuing,

Just PLEASE USE GOOD HOOKS AND RUN THEM INTO STUDS! I'd guess that is HEAVY and probably wouldn't feel good if it fell and landed on you!

dude, you are seriously not going to power it up?

The lamp looks fine, does it say "blue white" on it?

That fixture is in A+ condition, I wouldn't be worried to power it up once the frayed wiring is replaced. If you want to reduce the risk of it going "poof" (it probably won't) you could dim-bulb it first.

That thing is AMAZING

When repairing the frayed cord, it'd definitely be a good idea to install an inline fuse.

Very nice light! Can you take a better picture of the lamp? I or one of the other date code gurus can date the lamp for ya.

@Takemorepills: Yes, it does say Blue White on it. The RF came in two colors: Industrial White (4500K) and Blue White (6500K).

Power provider: Southern California Edison (SCE)

-Date decoder of some US lamps 1960-present.
-Switch and receptacle collector.
-I'll save any vintage lamp! Smiley

>It takes the positive & negative portion of the AC wave & makes it flow in one direction inside the bulb. The ballast is wired up in such a way that it uses a center tapped transformer to split both phases; using the bulb as a rectifier. This allows more energy to travel through the bulb while eliminating the stroboscopic effects of flourescent. These lamps are rapid start; with a starting voltage of roughly 500-600 volts. The light is clean & bright. These would be in theory the very first high output (HO) flourescent luminaires. The Westinghouse RF luminaire I have can either drive one 85W RF bulb OR if you connect both of the leads on the three prong plug and only one lead on the two prong plug to an F40T12 bulb. In this manner only 1/2 the ballast gets used but will none the less use a standard T12 bulb.

Wide-Lite 1000 No worries I will use 4 hooks and in the attic use nuts and large round spacers almost the same way I hung an early T-17 fixture but with that one I had to use large chains as well , A picture of it is in an early post, I’m in a 1930s house that has ship lap behind the sheet rock,

Take more pills To answer you’re question, Yes , The bulb reads Blue White.

Would like to Thank Everyone for Youre kind comments and suggestions,

Proteus - I wish I could explain in detail how these lights
Work , I was told they predate the T-17 and
Were designed to light areas that needed
Extremely bright lights,

I’ll take some more pictures of it in better detail and will also take pictures of vintage mercury vapor fixture saves
For Wide-Lite 1000 ,

It’s Ben awhile since I’ve posted here I’ve rescued a lot of lights in the past 10 Years,

Please get some more detailed pictures if you can, these extremely rare/ unique fixtures are historically significant to the development of flourescent lighting. They were quickly taken out of service due to the proprietary bulb design & its a miricle you have one of these luminaires. It’s my understanding that the Westinghouse RF luminaire I have is the only working one in the world & I am willing to bet this luminaire also works. The bulb looks like it would work fine as during their end of life; the negative portion gets extremely black. Put a 100W bulb is series with it & repair the damaged insulation sections & I’m sure you could safely test it.

I’m taking better pictures of it right now ,

I had no idea they were that scarce - I just felt I needed to make that drive up North to save it , since ai didn’t feel they were that many left in existence,

The Guy was extremely Nice - He only wanted & $75 for it I said $75 is not enough - I will be paying You a lot more for this fixture,

Cool, cool find!

That's a hell of a drive though...

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

I just got a case of these lamps if you need to get a working bulb for trade. I’m almost certain this luminaire works as it’s in extremely good condition.

Thank You very much for the offer- I’ll Think about it ,
If You decide to sell any of Your early F100T17
Fluorescent bulbs keep me in mind,

Also , Thank You for saving all the lighting in that cool wood frame building You have recently posted pictures of ,

With all the tornadoes, Hurricanes & floods we have had since You took and posted that picture dating back to 2007 there was concern that building might not still be around - So nice to find out the building is fine and You are rescuing some amazing fluorescent light history from it,

Keep up the good work and when a You get a chance I would enjoy seeing a picture of one of You’re F100T17
Brass Enders !!!👍

Awesome 👏 😎

This is incredible. Period. What a find.

This is an enameled white reflector, correct? The top view pic shows a shiny metallic-like grey that I've never seen done with porcelain enamel baking.

Also, correct me if I'm wrong, but since these bulbs are rectifiers in behavior, didn't the fixtures had to be run and mounted canted at an angle?

Miles , You are correct - For the light to operate properly
The fixture definitely had to be hung at a tilt ,

As uncommon as these are, I’ve seen bulbs for these pop up on eBay every now and then. The only thing is the ones I’ve seen run for over 100 bucks and are untested.
