Me too, though i'd like one with an internal PC receptacle. Very Happy

Maybe someday i'll get one...

So which design do you guys like more, the all cast Canadian one or the cast ballast case-stamped reflector US one?

I personally like the cast balalst housing with the stamped reflector.

And here's a surprise, I like the totally cast one. Razz

Could an all-cast clamshell pass as the first cobrahead? I mean this has a one piece upper housing (well, minus the electrical cover on top), and an internal reflector.

Well, no surprise here, I like the fully cast one too. Laughing

And yeah I wonder if these were ever consider cobraheads at one point...they seem to have all the features of them except for the cobra like shape.

I've never seen one of these. So the all-cast design was only found in Canada?

Cast seems logical up noth becuase of hailstoms. I'd guess a bad enough hail storm would damage stamped aluminum.

I've never experienced a hail storm... Just saying. Laughing

We've gotten hailstorms here but the hail was no bigger than a BB.

I've gotten hailstorms once or twice but they were also no bigger than a BB.

I find it so neat how similar...yet how different the Canadian Form 400's are compared to the American ones. Why the need for an all cast housing?

joe_347V

[Apr 19, 2014 at 01:21 AM]

I wonder if it's to make the fixture hold up better under inclement weather.

streetlight98

[Apr 19, 2014 at 05:07 PM]

Yeah I don't know. The stamped ones have a separate internal reflector anyways so the cast ones likely use the same internal reflector.

joe_347V

[Apr 19, 2014 at 10:39 PM]

Ahh, I thought the stamped ones would have used the housing as the reflector like in some gumballs.

Yeah I thought so too but the Form 400 and I think the OV20 used internal reflectors. My OV-10 uses one reflector. The inner reflector is also the outer one. The inside is mirrored (well it doesn't reflect an image but you get when i mean lol) and the outside is anodized.

Form 400 PowerPack

Here's a Form 400 PowerPack that lights an old driveway next to a rail spur. I believe there's around three or four of them left. Click here for the streetview.
