Hello everyone... in case you're interested, I had occasion to catch a couple of incandescent fixtures on a 6.6A high voltage series starting up in LA last...
... The startup is slower than a parallel arrangement even with a modern electronic regulator. An incandescent lamp filament has a much lower resistance when...
... Enjoyed the video--and thank's for the note about the start up of incandescent lamps on a series circuit. Around 1965, the City of LA opened a new street...
Thanks Jim, that was really cool! Since I never had the opportunity to see a series incandescent circuit come on. My dad used to maitain one back in the 1970's...
I recently picked up a street light I would like to restore. Can anyone tell me anything about it and does anyone have a picture of one that is complete? ...
This one is in Portugal and uses Luxeon "Rebel" emitters inside a fixture made by "Bluespan." It looks fairly serious compared to those LED fixtures that I...
I'm looking to do this on the cheap, so here goes. I am looking for a traffic signal controller/sequencer to operate two signals + a pedestrian signal. I have...
... I remember this as a kid in the 60s-70s growing up in Long Beach CA, I would also notice how the lighs would get slightly brighter and then come down to...
... That's kind of off topic here. I've built a few traffic signal controllers, both for signal heads and ped signs, but I've never made one to control...
... That's a series incandescent head. It's hard to tell from the picture what it would have looked like complete, but it may have had a radial wave reflector...
See the following link: http://www.youtube.com/watch?v=Sh69ox6-Tv4 This is a series starting up in Salt Lake City where there are literally thousands of these...
... Those old series lights rock, I grew up in Long Beach CA and remember them in egg-shaped heads. In 82 they converted to LPS on series systems, 95 or so,...
I have the opportunity to pick up an old green shade radial wave. However, it is missing the porcelain bulb socket fixture. I have posted two photos of it in...
... That is definitely a high voltage series incandescent head. Unless you plan to run it as such, your best bet is to pick up a modern porcelain mogul base...
Thanks James! The guy who has it just told me that it had a brown porcelain insulator sandwitched between the light head and shade. The insulator held the...
... It will run on whatever current the bulb you screw into it is made for. If you do use an original series socket, you will want to disable the shorting...
Yup I agree, these series incandescents are way cool! I live near LA so I see these oldies but goodies all the time. About 17,000 of them left in the city of...
I happened to come across a very old 100 watt H44 Par 38 mercury vapor floodlight with a black opaque coating on the outside of the reflective coating. It had...
... I happen to have a blacklight setup with an H44 MV spot and H44 ballast, lamp is also admedium and has the woods BL lens. I cant remember where or when I...
Hi Stanley, Don't think there would be any difference between an H44 or an H38 as both are 100 watt merc lamps, and presumably both operate on approx 850 mA at...
I thought I remembered that there was a version of this lamp offered with the standard medium base at some point and I managed to find the evidence in an old...
http://www.lamptech.co.uk/Spec%20Sheets/Sylvania%20H44.htm Sylvania still makes the equivalent lamp with a medium base... but they can be a little spendy. I...
Philips apparently doesn't make it anymore. It was listed in the June '97 catalog I found but not in the latest catalog I have here, which was from 2004. I...
