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...
Billy - the site at the North end of Broadway is actually an LED test site! There are several others around that area... But that's the only one with...
I was thinking, because of the growing popularity, that LEDs could kill off the HID family of lamps. Would it be a good thing or a bad thing for you guys? I've...
As long as the technology continues to become more advanced, why not?  Energy consumption reduction would be wonderful, the white light will come...
Well to tell you my opinion, HID is junk for the most part. The only truly proven and reliable HID lamp is the good ol' mercury vapor lamp. HPS and MH...
... If they must take away HID, at least make sure this includes the dastardly HPS lights as well. Any change in those would be an improvement. Billy...
... Alleluiah, let it be so. I just saw some of those LED's (the ones I recently reported. They are really pretty. They don't look EXACTLY like the old MV, but...
What would be really cool is if someone would make an LED streetlighting source/head with programmable color; i.e. you could set it so emulate incandescent,...
It's not a streetlight head but something similar to what you are talking about I saw on eBay just recently. A programmable RGB lamp. Ebay item # 230392729422 ...
I think that the technology has to be developed so hat the LEDS can be used in cobraheads. They still haven't developed ones that are bright enough to replace...
