Getting up to an 84" projection with a 150 watt bulb may not be bright enough, but Ace or I Eat Flowers could probably answer better as they've got similar bulbs in use.
In an Ellipsidal no probs, at 100inches dag i get an image way brighter then a 250w HQI.

Hey Ace, No problem - however please don't take me wrong when I say I completely disagree. I know you use the GE lamp, and I'm not sure if that arc tube appears different (and indeed should be different as you've noted their longer expected lifespans), but these bulbs appear identical to those pictured at both the Phillips and the bulbman site I linked to in the first post.
I got the same bulb as you right here, its a buddies, not mine. By all means im not saying that your bulbs are used, for all i know it could be the angle of the cam taking the pic. I did mention this this because normally they are white when brand new, and i was only looking out for you just incase you got ripped.

The best way to tell if the bulbs are brand new or not, is if you see a long metal strip floating around in the arc tube they are new, if not they are used.

Hey Ace,

Good info - is there any chance you have a pic of the strip you are referring to or does it show up in the pics on the Phillips site? I'm not sure I know what you mean.

Thanks

Heya Task, i dont have a pic of the bulb with the metal in it, its not so easy to see through the ceramic with a cam. The metal strip is like a rounded peice of wire, its about 6-8mm long and you can move it around. Its only in the arc tube.

After the first fire up of the bulb the metal is gone, it gets vaporised into the halide gasses. Not all bulbs have a metal strip, some have metal balls such as the 250w HQI, but this particular bulb has the metal strip. If you dont have the strip or any metal balls, the bulb has been used. This is only for Metal Halide bulbs btw.

Hmm - I swear I can see tiny spheres inside the arc tube. I tried to take a couple pics, but with the flash it was impossible. I took this pic through a microscope eye piece with my digital camera, so please forgive the quality.

You have not replied to my mail, I guess that means I don't get any of the bulbs. Am I right?

Me2 - hey, wait... was that one of my Vacation pictures to Roswell ? I don't know about rattle since I didn't shake any, but they can certainly move. It wasn't easy getting a pic - I kept trying to illuminate the bulb with a LED flashlight, but the arc kept appearing too bright, so that was the best shot I could get with anything in it.

Megaman - I still plan to check shipping costs from the PO for you as I may have a bulb, but those who inquired on the first day have all ended up sending PayPal for two bulbs so I wanted to let anyone reading know they are all spoken for. I will send you an e-mail later today and let you know the situation.

Thanks
