Metal halide retrofit?

Metal halide retrofit?

Click to view full size image

Here we have something odd I discovered today at an outdoor (outlet) mall. At first glance this looks like a typical 100w PSMH recessed can. After taking a harder look, I noticed the reflector trim was the white baffle type used in
incandescent residential cans, with the "clip in" incandescent lampholder. Also, ALL metal halide recessed downlighters have a glass lens in the trim, these do not. Wanting to know what was going on here, when nobody was around I pulled down on the baffle trim of one of the lights to try to see any information. I saw the sticker right away, and yes, these are in fact standard Lithonia incandescent 120w max. cans. Ide be curious to know how they ballasted these, as this is quite the unconventional retrofit.

Some issues here are, no pulse-rated lampholder. And an enclosed rated lamp in an open fixture, which the lamp in the picture above was really that dim and couldve ruptured at any time.

If they used F-Can ballasts they could have just bolted them right onto the splice box. I've used non-pulse-rated sockets before and never had anything happen but I suppose it would be a good idea to use one. They could have replaced the sockets though. I do not like the idea of using open MH fixtures though. even with protected lamps I don't like open MH fixtures. I like the redundancy of an open rated lamp in an enclosed fixture, at least when used indoors. Outdoors I'd be fine with an open rated lamp in an open fixture or an enclosed lamp in an enclosed fixture.

This is a remodel can, not a typical joist-mounted can, meaning the entire can light is supported by the drywall with spring clips. Not only would the weight of an F-can ballast push it back out of the hole in the ceiling, but there is also nothing to mount the ballast to, its literally the can enclosure and a small junction box attached to the side. I just find this so unusual, as it alludes to the possibility of this being the original installation. I mean, why would a contractor go through the trouble of converting the incandescent/120v lights to MH, when it requires the drywall having to be torn out in order to install remote ballasts somewhere in the ceiling, then drywall reinstalled and finished. I just dont understand why proper HID cans werent installed regardless if the MH was original or an afterthought, there is probably 20 of these lights over a 2000-ish sq. ft. area

This would be a hack job conversion-the contractor should have ordered the proper HID fixtures and the proper lamps for them-IE a lensed fixture or opened fixure that can use the proper O rated lamps.Surprized this retrofit would meet codes.Fire the contractor and hire one to do the job RIGHT.

The ballasts are probably just laying on a piece of furring across two joists adjacent to the can opening, exposed wirenuts and all. I mean, we don't like what we see so imagine what's there that we can't see.

Or, if they were really crazy, there's a PSMH yardblaster up there modified to power this recessed can light.

they were definitely magnetically ballasted, given the flicker from a few of them that were close to EOL.

I have a 70w PSMH recessed can (electronic ballast) that has neither a glass sheet or a protected lampholder.

Any machine is a smoke machine if you operate it wrong enough.
