A final attempt to turn on the old General Electric metal halide bulb

This is the last time I'm gonna turn on the bulb because it may explode as every packaging alerts when Metal Halide reach the end of life...

Absolutely massive!

[@jetpackjbd]

Holy crap, I never realized how large those actually are!

[@THEBULBHOME]

Me neither until I got it! I thought the size was similar to the 250W version! Boy I was wrong! haha

[@sovb]

Curious!! I have this exact same bulb, yet brand new. Even a fixture for it to work in... Will wire it up soon enough :D

[@davida.p.9911]

Works really good💡

[@THEBULBHOME]

Yes! But is scary when it starts! Haha

​In my school, there is a corridor that is being lit up with the exact same bulbs! It is so interesting, every morning before the lights are turned on, I would just stand and watch those big boys start up.​@@THEBULBHOME

I heard thunder!😀 R.I.P metal halide lamp

[@THEBULBHOME]

yes! haha poor old bulb!

why MH bulbs dont use Aluminum Oxide tubes

[@TheSoxmania]

You can get ceramic MH lamps that use an alumina ceramic arc tube exactly like the ones used in HPS lamps. Phlips, GE, OSRAM, Venture and more produce them as retrofits for Quartz lamps as they are more efficient due to the arc tubes being more dense and retaining the heat from the arc a lot better than Quartz. I have a video where I run a European Philips 150w CDO-TT, which is a ceramic MH lamp designed to be a retrofit for 150w HPS / MH fixtures. kzbin.info/www/bejne/jIfWnHhrZtmZl80

@@TheSoxmania can u run electronic ballasts in any lamp

[@TheSoxmania]

​@@gradientgamer5480 You can in theory. The thing to remember is that you need to make sure that the current and voltage that your ballast is capable of outputting matches what your lamp is designed to run with, or you can under or over-drive the lamp, which reduces its lifespan quite drastically and can also cause unexpected catastrophic failure if the lamp is being grossly over-driven. Metal halide lamps especially like to go boom if they are overdriven past the point they would begin to cycle because the higher than norma internal pressures and constant temperature cycling would cause the glass or ceramic arc tube to weaken, eventually leading to the arc tube rupturing under pressure. To achieve that effect though you would have to REALLY be going nuts with the power. e.g, running a 50w metal halide lamp in a 250w or 400w enclosure for a number of months.

@@TheSoxmania i ran a HPS lamp with a Electro ballast

[@TheSoxmania]

@@gradientgamer5480 I have as well. I also have electronically ballasted 20, 35 and 70w metal halide lamps as well... Still need to do some vids on the 20 watters. They're really cool little lamps! Not to mention I also have some automotive lamps that I haven't done much with yet... Might show some of them off at some point too
