Another ComEd ITT Model 25, except it's on a separate pole. The arm also appears to have a smaller tip at the end for the slipfitter. Not sure of the wattage, could be 250 or 400, but definitely a Merc.
Obviously that was a retrofit. Once small size cobras were invented GE used, 100, 175, and 250w mercury lamps were in small fixtures. 400w was medium, and 700 and 1000w mercury lamps were large. For HPS, 70,100, and 150 were small, 200, 250, and 400 medium, and 1000 was large.
I'm sure you could also order a 50 watt 327 if you really wanted too, the 125 comes in 175 watt MH and the (shudder) new M400 comes in 70 watt HPS! I'm sure the model 25 came in 250 watt MV as the 327 came in 400 watt mercury.
This fixture was just replaced with a new Cooper OVX FCO fixture. Unusual, since ComEd rarely uses Cooper fixtures and recently has only used GE M400R3's. However, there are a couple other ComEd OVX's in this municipality.
Geeze what, is everyone ditching GE now? lol Here National Grid is using Cooper lights too (for 250W and 400W). 50 and 100W HPS is still GE though, but it could be leftover stock...
Ok the new Cooper fixture is on a brand-new mounting arm. Makes me wonder if the previous fixture/arm got knocked down or fell somehow. I will try to get a pic of the new one.
@Joe i agree.
Here's what I want....
I want a Cooper OVH with 1500 watt MH!
