Yeah, but they don't mount on a wall.

I believe he was referring to just the wire cage in the center picture. If he could take the cage and affix it to a flanged porcelain med. screwbase socket he'd have what every dressing room currently has. He could use 1) 60-100W A-Lamps, 2) coiled compact florescent lamps, 3) LED-based A-lamp, or 4) I have a package in my hand from HomeDepot:
On the front of the package: "n:vision Soft White A19 60W equivalent." "Save up to $37 in energy costs per lamp." "Lasts 7 years. Warranty*." "800 lumens" "*8000 life (Hours)." On the back of the package: "Mini Spiral lamp, Fluorescent Bulb, 120volt-14watt, 2700k." "This device is not intended for use with emergency exit fixtures or emergency exit lights."

I suspect the last statement is included because the lamp takes up to 120 seconds to attain full brightness. This is my only gripe thus far with them, that and the fact they are not dimmable. Every switch controlling a permanent fixture in my home has been replaced with a slider dimmer, of course. But this bulb works fine in my bedside table 360Q lamp, and I bet it would be a great makeup mirror bulb as well. One caveat--Don't believe "All fluorescents radiate less heat." This lamp measured 165°F surface temperature after 15 minutes of operation.

Back to the point: Seems wasteful to buy a "drop light" just for its cage, but i'm sure the unused bits would eventually be deployed in another project. I'm envisioning a total of [email protected] 4x4x2" hex boxes (3 vert, 2 horz, 3 vert) for Light Devices at each mirror, plus a local switch and GFCI outlet, so a total of 10 boxes connected by 1/2" conduit nipples, or for a much more elegant look, a paintable Wiremold-type product. Finding the proper porcelain socket with the extended neck to accept the metal collar of the cage may be a problem. I would purchase prototypes and build a mock-up to get written permission from my electrical and fire inspectors before proceeding.

As I stated before, I suspect wire cages do not meet current codes, which is why they're so hard to find. Now someone go search for the correct flanged porcelain socket with extended neck that would accept the wire cage and post what you find.

Hold your horses there Gaff, it ain't over yet. Yes, pages 13 & 14 of the pdf do show the cages available separately. Now show me a compatible flanged socket. I'm waiting.;)

Then prove to me both meet all current codes for use in proximity to humans, or at least actors/dancers. [I've never needed steveterry so badly, even when my expression crashed 3 hours before a show. (Power supplied died, we had another next door, crisis easily averted.)]

Hey, Gafftaper, I seem to recall I heard somewhere that you're building a theatre, right?;) Care to share the architect's/electrical contractor's specifications for your make-up mirror lighting? If it's not confidential/proprietary, that is.;)

Here we are, a bunch of butch theatre electricians, all worrying about make-up mirror lights that we'll most likely never use.;) That gives me a little giggle.

By George I think she's got it. Once more; The rain in Spain...

Now, just the minor matter of proving our design meets codes...Bueller? Anyone? Anyone?

I think with a closed surface mount box and semi rigid conduit you should be good to go.(in most places)
It never hurts to ask an inspector or licensed electrician first.

I'd suggest ordering one of each. Taking a trip to Home Depot to pick out the fixture that fits best, then a stop in the office of an electrician or building inspector to see if it's ok.

As for what my dressing rooms will look like, that's one of the many pieces of information I haven't been given. I have a ground plan and that's about all. Everything else has been gleaned from desperate e-mails and phone calls to designers. It's a long sad story... but hey they are at least paying me now!

Congratulations. Now as the paid facility technical director, doors should be swinging wide open for you. So Tuesday (someone told me tomorrow, Monday, is a National Holiday) you'll call the architect and demand a complete set of all his drawings for your building to date?


Then you'll let us know the intimate details of your make-up mirrors?

Oh, wait, Monday is Columbus Day? Great, another "holiday", like Sweetest Day. Darn, that means I'll have to wait another day for my new gobo posters from Apollo. Some people put movie posters on their dorm walls, me.....

That also means that Tuesday is Leif Erikson Day.

I've already asked several times. The division Dean considers me a T.D. and wants me to have the involvement of a real T.D. in the construction project. The facilities department and contractor seem to see me as just another annoying faculty member who thinks he deserves special treatment. So I'm a T.D. charged with spending well over $400K in the next few months, but I still haven't seen all of the blueprints. It's a little nuts.

Oh and Charc... last I read it's more like "slaughter 1 million and let another 19 million + die of small pox day". Did you know that the diseases spread so fast that by the time the first white people arrived on the west coast, they found village after village with just scattered remains.

By the way for anyone who might want to learn the truth about American History. Pick up a copy of "A People's History of the United States" by Howard Zinn for about $20 or get it from the Library. I think the guy is a little too cynical at times about people's intentions. But it's full of real facts that are often glossed over or even cut from text books. I bet you were taught something about the pilgrims facing "hard times" before the Indians taught them to plant corn. Hurray! I bet it didn't mention that some of the Pilgrims dug up dead bodies to eat because they were incompetent and spent their time searching for non existent gold instead of planting crops (That wouldn't go over so well in the 3rd grade Thanksgiving pageant). My favorite thing about teaching U.S. history was my special Pilgrim debunking Thanksgiving lecture.

Hey Everybody!,
Thanks for the info, I'll tell Tyler, oops Actition, to read up on this thread as soon as I see him. He's a busy boy nowdays. He's currently in House and Garden, and still doing the Facilities Maintenance thing. With all the re-furbishments etc., he's "wornded - out" < as my daughter says >

"wornded - out"? I guess we know who her daddy is.;) Maybe you should send her here so I can teach her English. On second thought, maybe she should spend more time with Grandma--the person, not the Lighting Control System.;)

DANG IT Derek you beat me to it!

Although I did like the Ma pun... I probably wouldn't have come up with that.

Thanks all,

I think this collaborative effort may have solved it.

Having just purchased $4000 worth of electrical parts for our new and improved portable make-up tables (which the head carp. has yet to get around to building - 30 tables ea. with 4 mirrors), I have some - late to the party - thoughts.

1) My understanding of the US Nat'l Electrical Code is that all makeup table require cages. I have no idea if there are allowances for LED, Fluorescent or Lo-Vo, but in any case would (and am using) 15w incandescent A lamps due to color rendition as well as to alleviate heat.

2) You can get porcelain medium screw base lamp holders that mount on 4" octagon boxes and have collars for cages.

3) Metal cages were once very popular on construction sites to prevent damage as well as theft. Then they went over to reverse screw base lamps to alleviate the theft issue, then to yellow plastic cages as well as HID style lamps for energy efficiency. Thus metal cages are hard to find. They are available (Appleton ?) - but I have to go to work tomorrow and look up what our supplier gave us. I know they were $9 EACH, which really surprised me.

The comments about the cages being hard to find (as others pointed out, you see them on TV and in movies all the time!) peaked my interest so I started to so some searching and I did come across these:

Cole Lighting

Amazingly that seems to be the only purpose-built fixture that is easily findable. Several came up from across the pond in the UK but they didn't have cages - must not be a requirement there?

Now that you can get LED's in about any color temperature, I'm a little surprised there isn't someone out there making an LED strip for use with mirrors.

I also found this:

Aluminum Lens Guard - Hazardous Location Lighting Accessories - Hazardous Location Fixtures - Lighting : Grainger Industrial Supply

But I don't think it will work with a typical porcelain socket, it appears to be designed to mate with a particular explosion-proof housing (the bulb is completely enclosed in an airtight and watertight glass cover). The cost of the explosion proof fixter it's designed to attach to would certainly make it cost prohibitive!

We use something kind of like this with a 34w A19 in it. LED's still aren't ready to go into a dressing room, they're good for straight out of the lamp flood, but still don't spill out of the sides like a normal incandescent lamp or even a cfl.

Doesnt matter
not to mention they don't do well for color. One of the biggest reasons why there are so many lamps in dressing rooms is for when the actor/actress is putting on makeup they can tell where issue areas are based upon what would be seen under stage conditions. LED's are still too spikey in the levels to do anything like that.

Just a bit of a necropost here, but I'll go ahead and reply anyway.

Bulb guards are incredibly easy to find. McMaster-Carr carries them. Grainger also has a limited selection.


McMaster-Carr


Grainger

Personally, I like the guards from McMaster-Carr better. I actually need to order a few more for some lights on a set this season. I ran out about two weeks ago.
