Westy RMA With a Type III Bucket
I got two of these with the Type V. The Type V is acrylic and branded Lexalite while these two are polycarbonate and unbranded (though I suspect they're Lexalite as well). These are ever so slightly yellowed but you can only tell when you have them on a white surface. 

Note that in the pic I believe the bucket is reversed 180 degrees of what it should be (house side and street side are reversed). When I lit this, the side facing the front of the light emitted less light, so I'd imagine that is the "house side". There are no markings whatsoever on the buckets to assist in that so I'm guessing these are OEM refractors which would have been pre-installed. 

The Type III buckets are pretty cool. They're not incredibly efficient though. They attempt to redirect the light sideways (up/down the street) but mostly they just block light on the house and street side to obtain that asymmetrical pattern. The asymmetrical prisms are pretty sweet though!

And no, it's not as thick as the bottom may suggest. The bottom has a lip on it. The actual bucket is quite thin (like 1/8" at most) but since it's polycarbonate it's pretty strong. The acrylic ones are thicker since acrylic is weaker (that is until polycarbonate discolors; then it's a fraction of its original strength. Acrylic wins out in the long run).

Special thanks to Joe Maurath Jr for these two Type III and the Type V refractors. :-) (Plus some other goodies I'll post later.)

Interesting, must be kinda rare since most buckets are Type V.

Yeah the Type III NEMAs aren't all that common. I'd love to install one of my NEMAs up on a pole in a dark area with one of these Type III buckets and see how good of a job they actually do. I know it's not as clean of a pattern as a cobrahead. From what I understand, these really still make a Type V pattern but it's just dimmer than the Type III pattern they create lol. It's hard to create type III optics from a vertical lamp with a 360-degree refractor. I think internal glare shields on the house and street side might help a bit more.

Yeah, I noticed my mini gumball dosen't really create much of a Type II distribution but more of a Type V. It could also be the small room I use it in along with the fact that the lamp isn't centred 100% correctly in the reflector.

I usually use a 39w CMH which requires a E26 to G12 adapter which makes the arc tube stick out around a inch compared to a ED-17 which can centre properly. I suppose when I have the time, I could make a new socket bracket with a G12 socket for use with 39w CMH lamps. I would use the original bracket with a G12 socket but I don't like modifying original parts.

I agree, I don't like modifying original fixtures either. If the fixture is already not original I'd be more open to customization but for really old or OEM fixtures I wouldn't disturb them.

Yeah usually I modify my fixtures in a way that I can undo all the modifications I did and return it back to as original condition. Usually for things like brackets I either use the existing hole patterns and if that's not feasible, create a duplicate part and modify that.
