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?
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)
head hamging, kicking dirt with my boot 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).
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'....
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!
