metal halide led replacement

[Krusscher]

I have some 277v track lighting with these metal halide bulbs in them https://www.lightbulbs.com/product/ge-43273. I am wondering if there is a way to retrofit them to led or if it would make more sense to but led heads.

That’s going to be a tough one, it would have to be a ballast bypass more than likely, and finding a line voltage with that pin configuration……..

That, and if you do find, the output will likely be substantially less.

Probably cheaper to replace the whole fixture!

Is this a Dick’s Sporting Goods? I seem to remember on some stores they took over from Gallion’s? That had those funky track heads.

no its a college. this building was only built 8 years ago so I'm a bit surprised that none of it had LED's in it

Yes. The MH says it's 97 lumens per watt.
I'm wondering why even try to change it

They seem to burn out quite often and when they do they mostly crack and break and are a pain to change out. There is something to be said about longevity in a lamp when you're an electrician at a facility. Maybe not so much if your a contractor

Oh, I thought you were looking for job security
I jest, I jest

If you try to cram that much LED into such a small enclosed space, you're almost certain to have failure rates much higher.

The track head is not going to be designed with that much heat dissipation

And I really doubt you'll find anything close to 3400 lumens in an LED that's only ½" x 3"

An LED track would be the way to go

Actually, I got through with doing this some years back as the unit's ballast did have multiple voltage taps , one of the being 120 volt and I just rewired to suit, please ensure that the led heads are exact "drop in ' replacements.
I have also used mercury/sodium/metal halide type ballasts as step up /step down transformers where only small power was needed- never forget to use a fuse or breaker in the circuit.

Replacing the entire head is the only way to maintain the desirable beam pattern. You can't just dump lumens out anywhere within the head. The existing optics expect to have the correct sized "ball of light" in correct place to deliver the light beam as designed.

An expensive bulb, lots of cost if they burn out quickly. I would look into LED track heads. I have no clue what is out there now. Haven't handled any track lights in a long time. i would assume a few LED's are available.
