B2255 was replaced by a Cree LED.

Hmm, yeah the B2255 went from a common sight to a rare sight in the span of a few years.

They've been pretty rare over here for a while but now there are just 6 IIRC. 4 of them are all within 1 or 2 km to each other too. I know Vaughan and parts of Toronto still have a fair amount of them remaining.

Yeah, Scarborough still has a good number of B2255s, less common in other parts of Toronto but Toronto in general has a lot of older cobras still in use. Pape Ave. still has some late 50s flatbottom OV25s in use. Converted from 400w MV to 150w HPS in the 90s though.

Yeah its gonna be strange that soon all the powerlites are going to become rarity's. Difference between the MV-HPS changeover and HPS-LED is that the LED's guarantee the old cobras get scrapped.

What I find weird is that LED wall packs are typically still the oldschool HID design with just a corn cob bulb or LED tray inside but yet no one is using LED traditional cobraheads? Those wallpacks are glarebombs too. I actually like the LED-designed FCO wallpacks I've seen but I don't see them as often.

Yeah I've noticed that too, a lot of LED wallpacks with the HID look but I wonder why no one makes LED cobras like that. I find the HID look LED wallpacks to be kinda cheesey but yeah the FCO ones look pretty sharp.

I especially like these RAB wall packs, designed to replace "tall packs" by doorways:




If they weren't so expensive I'd buy one for the back yard...

that looks like a huge philips screw head

The plug on the bottom? It's a 7/8" threaded knockout for conduit. I normally use a large slotted screwdriver for those.

Yeah a lot of wet location rated lights and boxes use those threaded knockout plugs to seal better. Usually the ones I see have a big slot.

Is it 7/8s or is it 1/2 in ? on the knockout ?

They're usually 1/2 NPT which will fit in a 7/8" through hole. Some lights have a 3/4 NPT fitting which needs a 1" through hole.

A standard knockout for 1/2" EMT or rigid is 7/8". In the trade they're usually called "half-inch knockouts" since half-inch connectors are used but if you actually measure the diameter it's 7/8", particularly the "dry location" KOs seen on junction boxes and fluorescent lights.

Sizes in the electrical world are all screwy lol. For conduit benders, a 3/4" conduit bender will bend 3/4" EMT or 1/2" rigid, a 1" conduit bender will bend 1" EMT and also 3/4" rigid, and so on.
