GE M-400

GE M-400

Click to view full size image

This M-400 also came from the car wash that my OV-50 and the "swiss cheese" refractor M-400 came from.
I repainted it and lubed the latch before installation. Since I don't currently have 240v in my attached garage yet I'm running it TEMPORARILY with a modified cord attached to my dryer circuit. It's only hooked up when needed !
YES, the pole is 2" EMT conduit. It's attached to the garage with 2 EMT straps at the roof line and also has 2 braided cables to further brace it in place. So far it's faced several wind storms with out so much as a wiggle !

Looks nice Tim, but I'd be a little wary using EMT considering the weight. Hope it holds up!

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

Is this mounted to your garage roof?

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

Thanks, so far so good ! when I made this pole I did weld the couplers to the adjoining pipes on the back side above and below the set screws for a little more piece of mind . This is attached through the fascia board with (4) 3/8" x 3" galvanized lag bolts directly into structure. There is only 6' of conduit above the roof line and it is further reinforced with the 2 sections of aircraft cable, one keeps everything from wanting to fall forward and the other prevent a fall sideways away from the garage. the base consists of a concrete pier block keeping the pole from ground contact and since the ground slopes significantly towards the garage on that side (2 ft elevation change in 6') there is virtually no chance of the bottom trying to kick out. I also plan on anchoring the base to the garage wall anyway I just haven't gotten to that one yet! (WAY TO MANY PROJECTS AND ONLY ONE ME!

Besides, this is almost exactly the same set-up (minus the elbow) that I just when I put up the 1000w Wide-Lite almost 10 yrs ago on the back of the other garage .

I did a setup very similar to yours when I was a teenager at my folks place, but used 1-1/2" GRC that was 8' above the roof line (and penetrated 2' below) and secured to the inside wall of the garage with strut, and having a slightly later version of the M400R installed...the only difference is that it had the thumb tab on the latch, a twist-lock PC, and the original ballast was blown and replaced with an Advance 400W/M59 (H33) ballast using a 400w MH lamp. Not only was the garage door area lit up, but the vehicle car parking area as well. There was enough space between their house and the neighbors so as to not bother them. I wish I could do this at my place now, but I'm to close spaced to my neighbors, and they'd complain. (I look back at my parents place with nostalgia, where I could 'play' with all kinds of lights as a kid...what a fun time that was, and I had about seven cobra-heads installed...five were 175W MV first and second gen Westinghouse OV-15's...they had 2 acres with several out buildings and a 25' pole in the middle, which had an LMI-McGraw-Edison Unistyle-400 installed about 18' up.)

Looks good! As for the EMT, the pipe itself is more than capable of holding the weight IMO. If anything it's the coupling that will fail first.

Were you unable to source the correct color the light or did you want to use this color?

I always used galvanized rigid conduit in 3". Buried 3-4 feet of nipple in concrete and screwed the 10 ft sections on top. Took 2-3 men to do it without cross threading the joints. Looked pretty good because we used a level to make sure the top of the nipple was perfectly level.
Everybody has different ideas. Westy Ceramalux gets an "A" for ingenuity!

The light won't attach to anything larger than a 2" rigid pipe. Did you use a reducer at the end or something?

Drilled a hole for the main thru bolt and two 1/4 holes and threaded them for lower mast mounting secure.

Ah I see. Sounds like that set up is just about indestructible! I've seen mini transformer bases for sale online which accept different size threaded conduits and always thought it would be cool to make my own pole. 3" pipe is the perfect size for most post top lights as well.

The mini transformer box could be used as a remote ballast box too.

Yes it could. Be careful if the boxes are not heavy duty because they will break more easy than the conduit. A "weak link" in other words and down she comes.

The color was a goof on my part, I guessed on the paint as this LOOKED right at Wal-Mart but the 1st coat said it was WAY WRONG ! At which point I just went with it, I'll fix it eventually!

As for the coupling, I didn't trust just the set screws holding everything together so it is also welded with a 1" long bead where the coupling meets the elbow and where it meets the vertical conduit above and below the set screws. Also this is a galvanized steel coupling NOT the cast style !

The closest paint color I can find is Krylon "Pewter Gray". It's an extremely close match to the OEM paint, but I recommend spaying a clear gloss enamel top coat over it, since the Krylon paint scratches easily and it will turn powdery after only a couple months in the sun. Ah yeah the steel couplings are way better than the cast ones. I hate those cast ones. My boss doesn't even buy cast couplings, mainly because they can't be used with fire alarm systems. So rather than stock two different types he just orders all steel ones.

I'll use the Krylon next time, this was Rust-oleum . So far this stuff is holding up well for almost a year in the elements !

I've actually broke the cast couplings by tightening the set screws with my cordless impact driver!

Yeah I use rustoleum for everything else since nothing really compares to it imo, at least as far as aerosol paint. I actually use the rustoleum clear gloss enamel as the top coat. Rustoleum smoke gray works nice for older gray flourescrnt lights as well.
