Here is the instruction sheet for those fixtures, click the image to read it.
It pretty much tells you all about the fixture and what not. And they call it the "M-400" and "M-400A" But we call it the M-400 R3 and M-400 A3 to prevent confusion from the 1959 M-400 or the 1960's M-400 A.
I scanned this as it came with my M-400 R3 I got new in box. Nice to have this! Especially a brand new M-400 R3.
The only thing I don't like about the M-400 and M-400A is that they look so similar. Not much of a design difference like there was between the M-250A and M-250R and M-250A2 and M-250R2 as well as the M-400R2 and M-400A2.
Two things, if you recall the M400 split door and M400A1 were near clones as well. The only sure way to tell without getting closeups of both luminaires, was the vents on the rear door.
Second, there is another way to designate the current M400, GE uses alphanumeric for their models. For example, the single door version would be designated MSRL.
Another factor is now, you have newer lighting technologies emerging and I agree, streetlighting for the most part has gotten bland. Thank goodness companies have retro fixtures available.
Yeah. i like the fact that GE brought back the M-400R2 and M-400A2. Since they use the same glass and the M-400A2 uses tha same powr/module as older generations, fixtures can be repaired instead of replaced.
on another note though, is there a reason why all small wattage cobraheads have the same refractor footing but medium sized fixtures don't?
I still see them get installed, in matter of fact recently in Columbia just 3 months ago they installed GE M-400A2 FCOs in Bronze color! Same goes for Washington DC that are still doing new street lighting project and ALL of them are GE M-400A2 FCOs.....
Don't forget Chicago, still installing GE M-400A2s!
