I thought that these were replaced with OVZ's?

That was on my grandmothers street, mine still has Twistpaks for now, if/when they replace these I want to get an entire pole with the top reflector and refractor and ballast.

An entire pole! Well, they're only 14 feet high. I have a utility pole in front of my house that rises to 50' above the ground.
gailgrove   [Apr 10, 2011 at 10:33 PM]
Really? a 50 ft utility pole in a residential neighbourhood, these are also aluminium so I doubt the're very heavy.
streetlight98   [Apr 10, 2011 at 10:38 PM]
At least that, plus the undergorund part needs to be added. The light itself is mounted about 30 feet and is 100w HPS. I'll take a picture.

A pole! Shocked can't do that in my neighbourhood, the poles used here are around 25-30 ft tall.
gailgrove   [Apr 10, 2011 at 10:44 PM]
I looked it up, according to GEs site a 20 ft tapered aluminium pole weighs only 50 pounds and since these aren't even that tall it would be fairly easy to move.
@ Joseph yeah a pole, it would have to stay outside though, if they do replace them soon I might be able to put it up in the backyard.
streetlight98   [Apr 10, 2011 at 10:47 PM]
50 pounds, plus like 30 pounds for the fixture brings you to 80lbs. A metal pole would be eaisier to have around than a wooden utility pole like I have. Laughing
gailgrove   [Apr 10, 2011 at 10:51 PM]
Yeah I guess thats about right, plus the top canopy can come off as well as the ballast tray.
joe_347V   [Apr 11, 2011 at 02:45 AM]
Yeah a aluminium pole should be easier to put up. Maybe the fibreglass ones too. The concrete poles in my area on the other hand... Laughing
gailgrove   [Apr 11, 2011 at 02:54 AM]
Yeah, even the 10 ft concrete ones weigh something like 400 lbs Shocked
joe_347V   [Apr 11, 2011 at 02:58 AM]
Shocked Wonder how much did the old concrete freeway light poles weigh. Or imagine concrete high mast poles. Shocked
gailgrove   [Apr 11, 2011 at 03:00 AM]
Tons, theres a reason cars tend to get wrapped around those poles instead of them getting knocked over Shocked
joe_347V   [Apr 11, 2011 at 03:05 AM]
Yeah that's why they don't use concrete on freeways anymore, even the steel ones have a breakaway box if they're not behind a rail or on the median.

I have a old DHO document with crash test results of various poles used in Ontario...iirc the concrete poles were the worst when tested.
gailgrove   [Apr 11, 2011 at 03:08 AM]
I prefer the old non-breakaway poles, the cobrahead survives the accident Laughing
(yes I'm cruel) Could you possible send me that document?
