Dear All

Kindly Share The TIPS For XENON Lamp Life Extention and increasing of Intensity and Realted of lamps

Thanks And Regards

- Don't strike the lamp (turn it on) if it isn't needed, and leave the lamp on rather than turn off and back on if it will be off for less than half an hour to an hour. Lamp starts damage the electrodes slightly, equivalent to about that running time.
- Leave fans running for 10 minutes after lamp shutdown
- Make sure there is enough exhaust airflow and that internal lamp cooling fans are clean: these clog with dust rather quickly especially if the projector get oily air. If you can smell snack bar cooking smells in the projection booth, it is getting oily air.
- Rotate the lamp (if possible) about 1/2 of its warranty life.
- Do not extend life past the lamp's rated service life (check the lamp data, this is a more hours than the "warranty life") as a lamp failure past service life means you pay for the lamphouse damage; presumably the India lamp warranty is the same as here and the lamp maker pays for damage from a lamp inside its service life. Replacement mirror kits are $2000+.
Inspect the lamp regularly. If the light is flickering or the envelope is going dark, it should be replaced. Flickering or hard starting lamps should be returned for a warranty claim. Darkening envelope may suggest low cooling airflow.

Thank you Dave sir For Sharing your expierience

If applicable to your situation, stop shows when attendance is 0. In my experience, any multiplex operating 7 days a week will occasionally have shows where nobody shows up. Turning off the lamp after 20-30 minutes of no ticket sales will conserve bulb hours. In my smaller auditoriums, this may buy an extra week over the course of the roughly 6 month life of the bulb.

Look into the "L" line of Ushio bulbs.

For example:

DXL-30BAF comes out at 1300 hrs for warranty pull.
DXL-30BAF/L comes out at 1700 hrs for warranty pull.

Stay away from Osram and Philips bulbs.

Good luck - Monte

Actually I have had very good luck with Phillips XDC-3000b. Using them in a Barco DP2K23B and DP2K15C. Bulbs have never flickered or failed to strike up to their warrentied hours of 1500.

Dear All
How to dispose a used lamp safely and what are the remedial for flickering of lamps for continuing a show upto show hours?
By Shibupaul

A flickering, unstable lamp can be anything. Unstable power supply to the lamp, driving the lamp at an to high amperage, a damaged cathode, etc. If you have the issue only with the current lamp, it's most probably a lamp related issue and might be a warranty case.

The manual of your projector should contain lamp replacement instructions. Philips also provides this video on-line for a CP-4230, so you get an idea. The procedure for a CP-2220 is similar, but you should still check your manual for the differences.

To dispose a bulb safely and never toss an unexploded bulb in the refuse bin for liability reasons:

Have the bulb in the hard plastic clamshell and place it back in the box and tape the opening closed. I usually take out any supportive cardboard so the clamshell is the only item in the box and unsupported.

Do a dead drop of the box from a height over 6 ft and the sudden impact of the box hitting a hard surface will shatter (explode) the bulb.

Toss the box with the shattered bulb in the refuse bin.

Posted by Carsten Kurz (Member # 5396) on 10-23-2014, 05:13 AM:

Some people wrap the bulb in multiple layers of old cloth, an old blanket, etc. (at least 2-3 layers!), then throw a brick on the center part. Then discard with the cloth.

If you're afraid to blow things up with those glass grenades, Philips and Osram also take old lamps back for "recycling" (at least around here), I'm not sure Ushio does so too.

I use them for target practice! We grind the tips of the lamps off and then fill them with Tannerite!

P.S., Do not try this at home!

We save up half a dozen at a time and on any given building maintenance day (Wednesday mornings) will lob the unshielded bulbs into the empty open-topped dumpster from the projection booth balcony. Makes for a nice show.

At one of my former workplaces there was an elevator in the building. My boss took advantage of this for xenon bulb disposal: he'd lock the car out at the top floor and shut the power off, then open the door of the floor immediately below it, and from there throw the bulb down the shaft three floors (about 50-60 feet, I'd guess) to the bottom. One kaboom later, climb into the bottom of the shaft with a dustpan and brush, clear up the bits of bulb; job done.

Looks like you could fill five episodes worth of Mythbusters with a bunch of xenon lamps alone [Wink]

Every single bulb a myth - busted.

OUR BIN FULL !

You should bust these BEFORE using them ...

That's quite a collection you got there. You're either running a big multiplex or saving your used bulbs for something special. [Smile]

Be careful though, somebody might also inadvertently label this as a potential WMD storage facility. [Wink]

Lots of tungsten that one can take to the recycle ...

Posted by Dave Macaulay (Member # 813) on 10-25-2014, 09:06 AM:

I tried taking the tungsten electrodes to recycle... ok, sell. They wouldn't take it, it has some radioactive Thorium added and that makes it unacceptable. The cost of refining it is more than the tungsten is worth.

The place here takes it, we recycle ours.

Recycling is a big problem ,Around Near 1000 used xenon bulbs in our custody.Philips Christie and orsam ...No Idea For What next ?

Posted by Marcel Birgelen (Member # 6801) on 10-27-2014, 08:31 AM:

If you're sitting on a bunch of 1000 used xenon lamps, you're either saving them since day and age or you're the central warehouse for a local chain I suppose?

I have no clue for your area, but here I would just call the manufacturers and ask them if they could arrange a return. You've bought hundreds of their lamps, looks like they could do a little favor in return?

I've no clue how recycling in India works. At least here, manufacturers are supposed to provide easy means of recycling, in many cases by law.

I'm also by no means a recycling expert and if you're talking about 1000 of those lamps, well, that's really quite a number. But this is what I would do, if the the manufacturers won't help: Order a big metal trash container from your local trash handling company and carefully smash them one by one, inside the box and plastic clam shells, just like you would do when smashing a single lamp. Make sure every single one of them is properly smashed, as you don't want to have one of those explode while being handled later on. Maybe it's also best if everybody involved at least wears protective glasses and some gloves during the process. Otherwise, it's really going to be a field day [Wink]
