Cost is one factor, phosphor life and color shifting/fading Tue, 10 Nov 2009 05:55:48 GMT Don Klipstein http://finance.groups.yahoo.com/group/streetlights-l/message/6196 http://finance.groups.yahoo.com/group/streetlights-l/message/6196 ... I have found that fog has spectral characteristics surprisingly equal at all wavelengths in the visible spectrum range. For example, fog thick enough to Tue, 10 Nov 2009 05:05:02 GMT Don Klipstein http://finance.groups.yahoo.com/group/streetlights-l/message/6195 http://finance.groups.yahoo.com/group/streetlights-l/message/6195 ... I am more optimistic, given photometric performance of LED lighting units of various color temperatures. (Overall luminous efficacy tends to be maximized Tue, 10 Nov 2009 04:10:40 GMT Jason Chapman http://finance.groups.yahoo.com/group/streetlights-l/message/6194 http://finance.groups.yahoo.com/group/streetlights-l/message/6194 Well I've actually thought of something similar to having colors change depending on weather! Like if its foggy....it changes to LPS color to break down Tue, 10 Nov 2009 02:23:00 GMT duckfeetbilly http://finance.groups.yahoo.com/group/streetlights-l/message/6193 http://finance.groups.yahoo.com/group/streetlights-l/message/6193 ... Oh please, don't give them any ideas. Next thing Seattle will switch to all LED's, but they'll all be the same flesh-colored lights they have now.

They still haven't developed ones that are bright enough to replace Sun, 08 Nov 2009 20:27:51 GMT leel@... http://finance.groups.yahoo.com/group/streetlights-l/message/6190 http://finance.groups.yahoo.com/group/streetlights-l/message/6190 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.

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 Sun, 08 Nov 2009 01:23:30 GMT duckfeetbilly http://finance.groups.yahoo.com/group/streetlights-l/message/6187 http://finance.groups.yahoo.com/group/streetlights-l/message/6187 ... 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.

The only truly proven and reliable HID lamp is the good ol' mercury vapor lamp.

Would it be a good thing or a bad thing for you guys?

No I havent seen the 6th street bridge lights yet, maybe someday I will.
