Powerlite/Sylvania B2227
Here's a Powerlite/Sylvania R37 fixture, It has a remote mounted photocell for some reason and a optional "seagull accessory" inserted into the photocell receptacle. Oddly there was also a seagull on this same fixture in Google Streetview.

Simple, The gull's butt is blocking the sun, so they said..."Lets leave that gull alone and install a new remote photocell!" Lineman : 0 Gull: 1!!!

I would have wacked that gull with my screwdriver. Razz

But isn't that GULL ASSAULT? Shocked

What the hell? Why would anyone chase cats with a weed whacker Confused

As far as I know cats bury their "business", mine do anyways and almost all I know of do. And I wouldn't want to kill any animal. Rolling Eyes

Well, there's plenty of poo in my lawn. I was exagerating when i said kill. I don't have the heart to kill defenseless things, but it does get you angry sometimes.
gailgrove   [Sep 19, 2011 at 01:07 AM]
It could be raccoons, I'd hardly call a cat helpless either. My cats always go in flowerbeds, both ours and the neighbours.
joe_347V   [Sep 19, 2011 at 01:17 AM]
Raccoons are quite a nuisance in my neighbourhood Mad , they love to dig through garbage cans/bags, green bins, recycle bins, etc.

They also try to pry open the shingles so they could go inside the attics (happened to my neighbour) and they like to live under decks/porches but covering up the space underneath will take care of that. Rolling Eyes

Luckily raccoons aren't a problem at all. there are very few of them here. Our trash isn't dug through fourtunatly.
joe_347V   [Sep 19, 2011 at 01:23 AM]
I keep my trash in a cabinet next to the garage and take them out on garbage day...better than having to pick up after some messy raccoons. Rolling Eyes
streetlight98   [Sep 19, 2011 at 01:26 AM]
Our bins are stored in the garage and taken out the day before trash day. (pick up is on Fridays)

GET BACK TO THE TOPIC Rolling Eyes

I like this light. Very Happy

"Powerlite B2227, (or the Sylvania R37) a small sized cobrahead that I THINK was introduced during the 1970's and used up to 250w lamps. They used either mercury vapour or sodium lamps depending on what the customer ordered. It later became the Sylvania R37 when Powerlite Devices was bought out by GTE Sylvania." Rolling Eyes

Did the post-Powerlite Sylvania ones have the exterior nameplate on them when they switched the name to the R37? the ones I'm trying to get don't have nameplates. They also all lack NEMA tags, though some of them have marks on the doors that look like a label was peeled off or fell off. So they probably originally had NEMA tags. They're HPS, I think 100W but possible 150W or maybe 70W.
joe_347V   [Apr 02, 2016 at 07:37 PM]
I'm not 100% sure about the R37, but the B2255s kept the external nameplates and the embossed Powerlite logo on the door into the Sylvania era. I believe all the Powerlite/Sylvania cobraheads should have a external nameplate.

Even the later ones like the R47 and the R7. My guess the nameplate fell off from the ones that you are trying to get. The mini gumballs were supposed to have one too but the one on mine fell off in service.

If you do get them, I'm curious what the interior layout is and what brand of ballast they used. The Canadian ones used mainly Sola Canada and Ballastronix components.
streetlight98   [Apr 02, 2016 at 11:16 PM]
Ah I see. Yeah no labels on any of them. I checked every single Powerlite on the property looking for a NEMA tag. No NEMA tag or nameplates. Some showed signs of a once-there NEMA tag though. The two in particular that I'm after don't have any traces of a label as far as I can tell. They also have their Lexalite lenses fully intact, though they're full of crud. I have a plan for removing them but I want a couple guys with me for backup/moral support lol. I guess I can make myself new nameplates for them eventually. I'm pretty sure the lights are 120V since there are incandescents still on the system. My guess is that they installed the Powerlites as a test run in the late 80s and the place shut down before they even did a full changeout. The lamps are lightly used BT25s (HPS) so they weren't used all that long. The PCs are dark in color like new PCs, which is throwing me off. They're a greenish color but I think they're discolored blue PCs, possibly Fisher Pierce units. The lamps must be Westinghouse/Philips if they're BT25 since I think Sylvanias would be the ET23.5 shape and GEs would definitely be ED23.5. I think the refractors are acrylic since they're all clear (the plastic that is; they're full of crap inside though lol) but who knows; they could be polycarbonate. Too bad they're not glass, but it'll make it easier to remove them. I'm going to wrap the lights in bubble wrap, put bags of leaves on the ground, go up on an extension ladder, loosen the two bolts on top without even opening the lights, pushing them off the arm, snipping the wires, and letting the lights drop to the ground. the bubble wrap and bags full of leaves on the ground will absorb the impact I think.

I'm also curious about the layout. Hopefully the lights aren't too taken over by bees nests or anything else that could be living in there. Probably half a gallon of muddy water inside those refractors lol.
joe_347V   [Apr 03, 2016 at 03:18 AM]
I'm not sure exactly when but I know the Powerlites and Sylvanias were pretty late in adopting NEMA tags so they might not have had NEMA tags from the factory. My B2255 from the early 80s didn't have a factory NEMA tag. The Powerlites used a green NEMA tag for HPS BTW. The nameplates should be fairly easy to remake though, the model numbers are quite simple and I guess you can get the date from the ballast. I believe Sylvania made BT-25 HPS lamps in the early 80s but I think they switched to ET-23.5 shortly. Interesting that they used plastic refractors. Over here the optics of choice for the R37s was a Holophane glass refactor.

Hope you can get them and stay safe Razz.
streetlight98   [Apr 03, 2016 at 02:21 PM]
Yeah I also noticed they tended to put the tags on upside down on the R37s lol. If one of them has a bad ballast I'm thinking of converting it to PSMH (either 70W or 100W) so I can have a low wattage PSMH cobrahead.

I hope so too lol I have it all planned out. Just need to make sure nothing unexpected happens lol.
