I'm a member of a group that runs an excursion railroad in northern California. We recently discovered a couple dozen streetlight fixtures that seem to be...
It is not difficult to convert an incandescent fixture to HPS. You could even purchase a yard light from Home Depot or a similar store, cannibalize it, and use...
... Yuck, why HPS? It is/was probably the biggest scam to ever hit the lighting industry and I shudder to think of the billions of dollars wasted replacing...
Did you say you have pictures of the lights on a web site? Which web site? Some modern yard lights have socket assemblies (heads) similar in size and shape to...
Hi Don, Were those fixtures in storage? Marvin ... From: Don Pomplun To: streetlights-l@yahoogroups.com Sent: Saturday, February 03, 2007 9:02 PM Subject:...
Hi Don As others have said, HPS is not a good choice. In my opinion, using CFLs is both the most economical and aesthetically pleasing option. I use CFLs...
Yes, they've been in a boxcar, I think, since the 80's. My guess is they came from Santa Clara, CA when they converted to cobra heads, since they were in the...
... The HPS reference only reflects my ignorance of the benefits of the other technologies. Which ever way, I'd like to be able to get the necessary parts...
... other ... That depends on the design of the fixture head. Most pre-cobrahead HID fixtures used a remote ballast arrangement. Modern ballasts are smaller...
... web site? ... folder ... I would call that a gumball, it's a bit of an odd one too, I'm not sure what it is. Are the lamps normal 130V bulbs or are they...
OK, gumball it is. I didn't see any manufacturer's labeling on it. I assumed it was a normal 130v 400 watt lamp, but now that you mention it, I'll have to...
You can get a spiral CFL as high as 85 W and 65K in color according to Lightbulb Depot's catalog. You might have to buy a socket reducer to use a medium base...
Not exactly "streetlight", but an area lighting question . . . Our railroad has a new carbarn (a Butler-type building about 40x125). We acquired some HID...
Hi Don, That's really cool. I hope you guys can use them. Do you have a parking lot that needs lighting? I guess you'd still have to buy the poles and...
Marv mentioned something I've been thinking about in this situation--parking lots. If you have a parking lot anywhere on the premises and I'm sure you do,...
If you install a 100W lamp in a fixture with a 400W ballast, HPS or merc or MH, it will burn out very quickly and might even explode- don't do it! As a general...
Lee, Thanks for all he insight & advice. This is looking more & more like "too much of a project". I just checked Ebay to see what the market is for vintage ...
Don, There are several people, including me, that would be interested in getting a gumball fixture like that. Before you decide to scrap them out, you may...

Yesterday, standing way back, we tried some swaps. A 100w HPS lamp in a 400w fixture caused the bulb to illuminate to "full" brightness, but then cycle off...
Overwattage is most dangerous with metal halide lamps because they operate at the highest pressure inside the arc tubes, typically above 3 atmospheres. HPS is...
The purpose of the ballast is to keep the number of amperes flowing through the lamp correct. The 100 watt lamp "protected" by the 400 watt ballast may have...
It depends. If the ballasts are equipped with capacitors, DONT insert lamps of the wrong type/wattage. Ballasts with capacitors are very sensitive to...
During a road construction through an older area of town, the streetlights were replaced with decorative acorn type fixtures. As I have never seen a HPS acorn...
