The well heeled patriots are having some interesting 'Flag Wars' here, the latest being a 20'X 30+' one being hung on the side of a large barn on a hillside facing town.

I have the job of illuminating it, the only idea i can conjure is some cantilever down lighting. Has anyone here found any goosenecks, or complete units that would fit the this need?

It seems that if you lit it from the bottom, you could place the fixture further away and get a better spread on the light beam. Fixture weight wouldn't be a concern, so you could go HID. Can you do this?

Redsy,
I only have the building, or the ground in front of it to play with. I suppose I could do a post & HID, but the cust. asked for cantilever's first. [Linked Image]

Our first choice is always a Metal Halide fixture or 2 mounted on or in the ground in front of the flag. No need for a post or pole.
(Maybe telling the customer what you'd charge him/her to replace the airborne lamps would change their mind)

Electure,

Can you use uplighting like that out in CA?
I thought you guys probably had light trespass issues to deal with along with your conservation policies.

Bill,
isn't it 'light pollution' here?

Scott,

Snow...uh, yeah. I forgot, Steve...uh,sorry.
Bill, The uplighting ordinances aren't a matter of CA regs, but of local ones. To me, it seems that there's no rhyme or reason to them (like all the other local codes out here, you can have a different whole set of rules to follow by walking across a street into the next town).

Sparky,

I'm not up on definitions. I think of light trespass as what your neighbor would complain keeps them up at night and light pollution as what the stargazers would be against.

Niether am I Bill.
Coincidentally, in my area we are a mecca for a star gazing group called 'stellafane' that all show up at certain celestial points in the year to count the moons of orion etc.
mostly Volvo driving, granola crunching quoters of Mother Earth news..

This group has comicaly opposed the building of a local prision, who's permimiter lighting would impede thier mission.

Conversly,
the Flag is supposed to be either lit up, or taken down at night. (correct me if i am wrong here) A VFW member once gave me a job , such as my original post, stating this. Pickup truck,gun rack chaw-on-dashboard,tatto says 'Mom'....

Methinks the two should do lunch... [Linked Image]

harumph!
Local Politial shenanigans aside, I have been surfing up some fixtures & thier photometric properties. ( Fueled by posters advice here..)This , also in consideration of 314.23(E)<changed for the 02'> would seem ineffecient as opposed to the same well placed pole mounted fixture.
Possibly 314.23(E) alone could save me wing rental here, if i could only figger it out!

sparky,
314.24(F)(exceptions) will allow up to 3' projection from the roof if the fixture weighs les than 20#. But, as I stated above 3' may not provide enough beam spread on such a large flag.
Posted By: electure Re: Cantilever Believer - 11/28/01 01:12 PM
The short pole or 2 sounds like a "best option" for you. You'll never get an even lighting pattern from only 3' away.
We also have had very good results from racks of "KC Lights" (the 12v driving lights like you mount on a 4x4 truck). The beams are very controllable. Drawback is lamp life.

Sparky,

Some stores by me have weatherproof single lamp 6' or 8' HO Flourescents that stand off the bldg at each end and can swivel inwards towards the wall. I'll bet a couple of those would give some nice even light. I don't know any info on the fixtures except they've been there for a long time. They are pretty slim and probably light because they use external ballasts (1 per pair) that are located inside the building.

There are several manufacturers of interstate sign lighting using HID sources. I don't have any catalog info at my desk but would be glad to look up some for you. May need a few more details. Also you can locate a local Rep, and they will be glad to help with the layout and fixtures (luminaires). If I can help, let me know.

At least you've got the problem of how to light the flag.

Flags aren't flown anything lie as much here as in the States, and when one guy in a certain "looney" area of London put up the U.K. flag the local council ordered him to take it down as they considered it racist. [Linked Image]

Sorry it's nothing to help you out but i had to get that off my chest. Makes me so mad.
