Introducing the 2017 McCann Lighting roadway lighting linecard, including the new R-Series single door family and the existing Linedorâ„¢ family.

LD250 Linedorâ„¢ Luminaire




LD400 Linedorâ„¢ Luminaire


R150 Luminaire


R250 Luminaire


R400 Luminaire


R1000 Luminaire



Note that the R150 uses the same glassware as the Westinghouse OV-10, OV-12, and OV-14. The R250 uses the same glassware as the Powerlite R37, R47, R7, Hubbell RMG, and some of the newer OVZs and OVXs. The R400 uses the same glass as the AEL 125 and current GE M-400. The R1000 uses the same glassware as the classic GE M-400 series, which I think also fits the Powerlite B2255s. The small Linedor light uses the same glassware as the R250 and the large Linedor uses the same glassware as the Westinghouse OV-25, Cooper OVM, and Cooper OVD.

I really like the R150. Kinda reminds me of the Howard USG3. Do any companies currently offer frosted flat FCO refractors? Also, why is acrylic HPS only? I know polycarbonate will yellow from metal halide UV, but what effects would this have on acrylic?

The LD250 and LD400 look like Hubbell cobraheads. The R250 looks like a M250R2 and the R400 looks like a Crouse-Hinds OVM Grin

@ Zarlog: Nope FCO is all clear tempered glass now, but when it first came out in the 70s and early 80s there were frosted/serrated FCO glasses. My OV-15TD FCO has a serrated glass lens. I like it much better since it cuts back on the glare from the lamp, especially when a clear lamp is used. The reason why all metal halide products are only available in glass is because the scorching hot shards of glass will melt into the plastic lens during a lamp rupture. Even with glass refractors the bits can really stick to the refractor.

Horizontal PSMH lamp explosions are particularly violent since the arc is less stable in MH lamps when run sideways. MH and MV lamps run better vertically. With the old medium pressure MV lamps, a vertical lamp was a must. For GE's Form 109, an ingenious device was installed above the reflector to stabilize the arctube, since the Form 109 has a horizontal lamp. The modern day high-pressure MV lamps that came out sometime in the 50s could run in any position. With MH, the lamps are not as bright when run sideways as they are when run vertically.

@ Ryan: LOL Yeah it's hard to come up with totally unique designs that don't look really oddball lol. The R250's door does look like a M-250R2s but the top housing is a little boxier like an ITT 13 The R250 was designed basically as an elongated R150 with a larger refractor (standard small cobra lens as opposed to the OV-10 glass on the R150) and longer housing to fit a 4-bolt fitter and larger ballasts.

When I initially drew the R400 it came out basically being a drawing of a Model 25 to a "T". If you look very closely you'll see the erased line of the door, where it curved upward just like a Model 25 door does. It uses a Model 25 glass too so it really was a clone lol. So to make it different I indeed modeled the door after the OVM. So my inspiration for that light was a cross between the OVM and Model 25 lol.

As for the R1000, it actually uses a classic M-400 glass, so it's technically a medium fixture (basically the 1000W version of the OVX lol). It was actually based off the Powerlite B2255 which looks a cross between an OVM and M-400A. Powerlite made the same fixture casting in 1000W and called it the B2228. The fixtures were the same other than using an inverted socket bracket, which set the socket further back so a large BT56 lamp can fit (a 1000W lamp indeed fits inside a M-400 glass!)

I do see the erased line lol. Got any plans to manufacture these?

It would be cool to manufacture cobraheads but no, I don't have any plans to. The set-up cost of casting molds is hundreds of thousands of dollars. It's takes millions of sales to pay off the machinery. But the per-unit cost is very low so that's why cast aluminum is used a lot in mass-production. Same thing with refractors. I'd love to get a bunch of refractors made for me (like the OV-10 style, since those are no longer made) but the set-up cost of the molds is insane. Even if you paid a company to do it they have to set-up the molds and they'd require you to purchase hundreds of units to pay for the cost of the tooling.

What if you were to make your own mold, by removing the internal gear of a cobrahead, and copy it using the powder stuff I have seen used to cast metal parts. There was an episode of How It's Made where they were making manhole covers and the molds were this powdery sandy stuff. They break off the "powder" after they cast them. You would just be replicating the same fixture, but that would be cool to be able to make discontinued fixtures. Sounds easier than it probably would be.

How It's Made simplifies everything they show big time. I'm sure it's not super hard to do, but you need the correct equipment, which is very expensive. If I were to start making a discontinued cobrahead it would either be the original boxy M-250A2 or M-250R1. The M-250A is my favorite cobrahead but ARK makes one that's close enough.

Hmm. Seems like it could be done cheaper, without having all the expensive equipment. Half ass, but still cheaper lol.
For G.E., I would make the M250R, the push button without the protruding tab. And original M400. I'd probably prefer the Westinghouse Silverliners though.

I prefer the 60s GE over the 70s GEs too but the M-250R1 would be easier since it's got fewer parts.

Well do you want to make the light you prefer or another one just because it's easier? If it was your business it would make sense to make the one with fewer parts though.

If I was going into business, I'd choose the easier one. There's a reason the 60s GEs got discontinued: too expensive to make! But boy do they look good!

They really do! Every time I go to my storage unit and open the roll up door, there it is. Right in front to greet me.
I still need to clean it. As soon as I got back in town from my trip to pick up all those cobraheads I drove straight to my storage unit and dropped them all off there.
