Check out this HUGE metal halide bulb I bought

[Handlobraesing]

Not that I have a use for it, but I picked one up from my school's Surplus Property department for $3, just so I can use it as a piece of decora.

1,500W sports lighting lamp.

Or something else...

Might want to build a better stand for that, arne't those under some amount of pressure inside? If that fell off you'd be picking quarts and glass and bits of wire out of your face/eyes/backside etc for quite a while...

I think they're actually under a vacuum, so it should just implode. Maybe the little "thing" in the center is under pressure, I don't really know...

TVs are under a vacuum, and if one explodes, you will never get all the glass out of your body. That light is a bomb.

That's a pretty impressive lamp. I wonder if the arc capsule is tilted for a particular beam pattern, or if it's made that way to reduce the overall height of the envelope.

I've seen a TV smash into concrete very near me, it imploded rather harmlessly. It is not possible for something under vacuum to explode unless you add explosives.

Regardless, I think it's pretty cool!

Stadium Flood light

I think the reason the arc tube is slanted like that is so that when installed in an angled socket/reflector, it would burn in the horizontal position. It probably also has something to do with the beam pattern. A lot of stadium flood lights I've seen use lamps with arc tubes tilted like that

Find yourself a 20 amp 120volt (240 or 277 will also work; its a multitap ballast anyway) and get a pair of sunglasses.

Normal application

And yes, that arc tube is probably around 2 atmospheres pressure when cold. Don't let it fall. Even if the HID explosion dosen't kill anyone, it will be quite a mess to clean up. Not to mention that those lamps do contain mercury.

That'd make a great 5-gallon jerrycan for your spare gasoline. ;-)

Thanks Yuandrew for the explanation and the great drawing, Handlobraesing!

I Googled this, (yes, very scientific research), but I guess TVs have a layer of tough protective polymer sandwiched in which prevents the glass from shattering all over. Thus, my mom lied to me when she told me the TV would explode if I threw stuff at it.

www.zyra.org.uk/tvtube2.htm[/url] describes the glass imploding then flying outward.

www.kronjaeger.com/hv/hv/exp/pump/[/url] also cautions against it.

Anyway, it looks cool - maybe just make a cool holder/stand for it? Glow in the dark holder would make for a snazzy backlight...

[bfg9000]

I'd try to get the ballast for it. Would make a fine nightlight for the true flashaholic.

nightlight??
i dunno how you can sleep with a miniture star in your bedroom hahaha

[Handlobraesing]

hmm rated at some 160,000 lumens.

[snakebite]

dont operate it outside a proper enclosure designed to contain an explosion.
it may make a good bang cold but the pressure is about 20 atmospheres hot.and a common failure mode is arc tube rupture while operating.and if the explosion is not bad enough you have nearly white hot quartz shrapnel to deal with too.

[watt4]

very cool. makes me think of flashaholic decoration themes.

need to make a proper flashlight body to hold it. five gallon bucket might work.
then send pics of the super flashlight around the net for comments


btw, that thing will fall over if left like that. only a matter of time.

[nakahoshi]

I have to change those bulbs all the time, so i dont share the same enjoyment as you do. more of a pain, trying to get into the fixture if there is a lense, ect. There pretty awesome though, when they first get power the inner tube glows blue and pulsates for a little bit. You cant watch them too much though, Unless your blind to begin with.
