Hi, gang! Found a note on the LA Bureau of Streetlighting web page. www.lacity.org/BSL/ Looks like the BSL is going to begin an evaluation of LED lights in ...
Well, I live just a few miles from the LA city limits, so I will keep an eye out for these things. From what I heard tho, the LEDs are very dim compared to HID...
Most LED's are directional, namely they aim most of the light in one direction. A cluster of them can direct a good amount of light on the street and very...
Hi Dave, all We got a few pics last year of a couple of LED test sites in LA...the results were not too impressive I have to say! This first one is actually an...
Up for sale is a 1966 General Electric M-1000 luminaire. This luminaire was obtained as part of a four luminaire acquisition from a reconstruction project here...
Hi, I have several series 6.6 amp 1000 lumen incandescant bulbs and the original fixtures to go with them. I would like to use these bulbs along my driveway....
... Hi Rich I once built a 12 volt, 300 watt landscape-lighting transformer into a single NEMA head for my display. It lit the lamp well, but threw ALOT of...
As I recall, a 1000lm 6.6A series lamp is about 72W, which would mean you need a voltage of about 10.9V to run one singly, or if you connected them all in...
Think about delivering 6.6 amps times 4 (26.4 amps total) through 400 feet of wire. If you get enough current to the first one, I'll bet the last one never...
A basic historical question: when and why did the electrical lighting industry switch from rating lamps by light output to rating them by power consumption?...
... As others have mentioned, with a 400 foot run you'd pretty much have to run them in series. Personally I would be inclined to save the scarce series lamps...
It's deja vu all over again! While it's a miracle that the lights along I-277 will soon be back on again, another major Charlotte road has gone in total...
Hi All, I'm an instructor over at Rensselaer Polytechnic Institute, in the department of cognitive science. This coming semester I will be teaching a course...

To update hte group: I'm going to take james' advice. I've found a company willing to donate a bulb, and will take your advice on the fluorescent ballast. I'm...
Oops, that was a hastily written message with some obvious errors, and needs a bit of clarification. James advised that I use a ballast made to run four F32T8...
When I was playing with SOX/LPS in the late 70s and early 80s, the bulbs were not easy to find and the sockets were impossible since SOX never really caught on...
Dear gD, ... I don't think there is such a thing as a SOX starter. I expect the ballast alone to make the SOX work. - Don Klipstein (don@...)...

SOX needs no starter at all. They start on the open circuit voltage of the ballast, plain and simple. Give it a go on the F32 ballast. I have matching...
... There is, I have a couple of them. They're used in places where the line voltage is 240V to run the small 18 and 35W SOX lamps using a simple choke...
I finally got my all-time fave, the OV-20. It had been removed from the parking lot of a local car wash when they changed the signage about amonth ago. The...
I'm happy for you. It's also my favorite from childhood; in fact I've got one lighting up the room as I type this. ... From: Sean <createworks@...> ...
That's what I'm hoping to do with this one, too. I suppose the first order of business is finding a suitable arm. Converting it to incandescent looks to be a...
Anyone know where I can get a new or used DURASTAR street lighting fixture? I donąt care whether or not the lamp or ballast work. They come in two size...
Hello Does anyone have a philips SRS201 with a gear shoe, which is long and runs on low pressure sodium which they want to sell? Cheers Oliver Hennessy...
Hi Sean, That's great news! What city are you in? I'm in Houston, and was able to get an OV-20 from the electric company here several years ago, along with a...
Hi Marvin, I'm in Chicago. I guess my next acquisition target will be either a Form 400 or an Ovalite. Still quite a few form 109s attached to older buildings...
