... I saw it after I had posted my response. Friends of mine own a machine shop, so I've considered trying to make a proper socket. Would not be impossible to...
I've seen those expensive admedium sockets. Seems ridiculous to pay that for a socket, even though it's an obsolete type. I like the idea of wrapping copper...
Hi, I have an external mounted 400w mercury ballast with 3 identical black wires coming out of it. It was working fine when hooked up to an old GE luminaire...
I hope you know what voltage it's supposed to have. Since there are only three wires, it's probably only a single voltage ballast, but you still need to know...
Hi Brad, I know you posted this awhile ago. I`m just getting back on line. Did you ever get the parts you needed to restore this light? I have some original...
Thanks for the quick response. It`s been awhile since I tried doing anything with it but it was wired to 110 volts when it was in service. So if I`m...
I've never messed with the potted ballasts and have only seen a few over the years. The wires probably were marked originally, usually with numbers, but the...
Doesn't sound right. When it's hooked up correctly you should get 120 across the primary but 240 or so from the lamp lead to common. Forget about the lamp and...
Thanks again for all your help, I`ll keep playing around with it..hopefully I didn`t blow it. It was a neat setup and very reliable until I had to take it...
Hi Gang! Los Angeles have begun the changeout from HPS to LED. Over 500 100w HPS lights in the Northridge/Granada Hills/Resada/Van Nuys area were changed out...
... i dont Think LED's are Quite Developed Enough to be a Mainstream Light Source for Roadway Lighting...LED's Simply cant Compete with HID Lamps Watt For...
... I've seen a few LED test installations around here that put out pretty good light, in fact some were stunningly bright, however the optics leave much to be...
Hi all, I would like to know the actual difference between SV/MV/MH to LED lighting, what u are talking, for that can u do a favour, pl take some photographs &...
... Ok first of all please make some attempt at using proper English, or at the very least full words and sentences. Childish abbreviations have no place in a...
... That's why I liked the Domus "Mission Bell" fixtures at the Granada Hills LED test site--at least they had some character! Folks--if I can pose a simpler...
There is a range of color temps for the HID stuff, but generally speaking, incandescent is around 2700K. HPS is around 2200K. Deluxe white mercury runs from...
You know Dave, I didn't think they were all that bad when I saw them- I quite like the look the lower apparent light level gives to the streets. Did you go see...
... According to my recollection, the traditional tungsten filament bulb is around 2700K. If you can get it to 6500K, that will have the cold white look of...
... Thicker filaments with luminous efficacy near 15 lumens/watt achieve more like 2800 K. ... 6500 K sources will vary in visual effect in streetlighting. ...

Billy/Don: Thanks! Where does LPS fit in in the temperature scale? Best Glen...
Gang: Had a doctor's appointment in Cupertino this morning, and passed what looks to be an LED test site on Torre & Pacfic Avenues, near De Anza Boulevard. ...
Welp, seems that AZ still follows CA in a lot of things. Behold the LED intersection at the east bound ramp of I-17 and 19th Av. This morning was the first...
I almost couldn't believe my eyes. But for those who may be in Seattle, I was driving along Broadway Avenue on Capitol Hill. That I did it after dark for the...
