Okay. I did some investigating at work. My work place has 8 of these. None are lit at night. 4 of them are over the emergency exits. The other 4 are over the ramp leading to one of the emergency exits. Supposedly they come on whenever one of the doors are opened.
Hi FGS, We have these at our Factory installed over Emergency exits. They are emergency lighting and are meant to provide sustained illumination for 90 minutes with loss of power. If they are not turning on they have a standard 5 year warranty-- we make them right here in Texas!
Thanks! Hi Mike, I'm Thomas. I do not work on the assembly line, but I do work with Engineers all over to provide lighting calculations for them. I found this site, because of typing in Mercury Vapor lamps---haven't seen them in awhile and remember them growing up. Nice little forum here, pretty nice pictures too! I do work at the factory however where these and many other luminaires are manufactured.
Yeah fortunatly mercury vapor is still very much "alive" on this website. Unfortunatly, come 2016, all MV lamp production will be ceased. It's not like the current lamps are any good though (besides Sylvania and EYE). The GE and Philips mercs seem to be a little flimsy in terms of quality.
Hi Aaron, What is it that you do? If you wanted, I could help you along the path. So Mike, I've noticed a lot of smaller towns typically still use Mercury Vapor, typically in old Tear-drop style refractors (My favorite!). I've noticed a lot of people have posted pictures of Cobra heads and old Yard Lights, is there a particular type that everyone agrees is the best form of street lighting? (Meaning, Lamp type combined with Fixture Style). I never would have thought a website like this would have existed, pretty sweet.
I am currently a student at Oakland Community College in Auburn Hills MI, taking a few pre-requisite classes before I get to the Electrical class
Help would greatly be appreciated as i don't have a job yet !
seems everyone likes different types of fixtures, i prefer Mercury vapor cobra-heads for general streetlighting and other areas the teardrop fixtures are really classy
This site if definitely one of a kind as well as another site http://www.lighting-gallery.net/gallery/index.php
Welcome to GoL Thomas! Fortunately at lot of us here have a good number of mercury vapour lamps and fixtures in our collections even though MV is rarely seen in use nowadays. I only see MV left behind in old parking lots and in some small towns. Occasionally in some indoor recessed lights too.
Welcome to GoL! It's nice to see you here, I am one of the administrators in this website, and look forward to seeing your posts or what you share. Thank you so much for the answers about the product above.
Where I live, MV is still very much alive, it's almost all over my state, almost.....
Thanks for the info on the light above. And welcome to GoL. I am Felipe.
As for the light working. I haven't had the chance to see it during power outages. The power company here is TOO reliable. And the store's generator doesn't give much time to see it fire up and turn off as the generator kicks in. Is there any reason why I have to open it up to press the test button?
