Hello everyone.
I have partially been following this thread, but I just want to make sure that I'm understanding this correctly. Please elaborate on or correct any of my statements below.
- ywh has found (and is now selling) a replacement "bulb" (the jyd) for the "lamp unit" used in many commercial projectors.
- Instead of spending $250-350+ on a whole new "lamp unit" after the original bulb is used up (usually 1000-3000 hours), you can just buy this ~$40 replacement (the jyd) and fit it in yourself.
- However, you have to make sure your commercial projector is compatible, and you have to make sure you get the correct version of the jyd bulb for your projector.
- This eliminates the need to retrofit your projector with a metal halide or similar light source.
Does this mean I can buy a compatible projector (I'm looking for something in the $500-800 range, like the infocus X1 or similar) and use these ~$40 bulbs as cheap replacements, all while maintaining the quality/features/benefits of my commercial projector?
I'm currently looking for a projector setup for heavy use (video gaming, etc.), since I don't have the time/tools to DIY myself. My options were to purchase someones DIY setup, to purchase a 7" LCD import projector such as the Ally/Riucheng, or this. My origial budget was around $300-400, but If I can get the quality of a commercial projector like the Infocus X1 for a little more, then the extra money is worth it to me.
Thank you in advance,
Jawadali

Got it- new problem
ymh,
I got the lamp today (thanks) and in the course of replacing the lamp I've run into a little problem and maybe ymh can tell what to get to replace it
Here is the bulb
The bulb and the original lamp
Rear of the original lamp
Top of the lamp
Top of the lamp with the holding clips removed
Closeup of the rear.
Here is the problem . Its that clayish material wrapped around the bulb. Its dry and removes like chalk but what do I replace it with. Its main function seems to both hold the lamp in the center (which in itself could be tricky) and keep the heat away from the rest of the enclosure. What material do I replace it with?

An externally hosted image should be here but it was not working when we last tested it.

Hi, Victor,
I've been wondering about how to go about this from when I first heard about these lamps. I know this has be talked about before on here, but does anyone have any tips for removing the cement?
As for what to replace the cement with, I'm assuming you could use some fire cement. It's that cement you use around the fireplace to hold bricks or tiles on? I don't know if it has other names in the US?....
http://www.purimachos.demon.co.uk/FIRE-CEMENT.htm
I did also think about using JB Weld, which is that liquid-metal stuff you use for repairing holes in vehicle exhausts. (no, not that stuff the Terminator T-1000 is made from!)......

I've considered just cutting the end of the reflector off on my lamp, but I wouldn't have thought that breaking the bulb itself is NOT a good idea because of the mercury used in most lamps.

Hi ! Jawadali
the JYS is MHL, $40 only, but JYD is ultra-high pressure mercury lamp, $65.
Hi ! victor-eyd
you can get the glue,it is to repair internal-combustion enginereplace,fot the piston,cylinder. it is fire glue.
you can get it in garage.
give me a PIC of your bulb core, I am no sure that is a MHL in you PIC.

Well I managed to scrape all of the chalk out of the bulb using a small screwdriver. There is a small ring that wraps around the metal casing of the bulb which in turn keeps it more or less centered. The chalk or goop simply serves as heat protector and holds the ring and bulb in place.
What I need is something that is heat resistant, comes in a tube, and will eventually be able to scrape off the goop at a later time and replace it with another bulb.
Whoops! ymh was replying the same time I was- fire glue for engines. Off to kragen!

You could use muffler repair paste.
It is the gray stuf that gets hard when it heats up.
And very easy to remove later.
I dont know the name of it.

Hi,
I just managed to remove the bulb from it's reflector on the Proxima DS1.... It wasn't quite as difficult as I thought it would be, you just need to scrape away the majority of the cement, then try pulling the bulb out. If it doesn't move very easily, then you need to scrape more cement away.
I wasn't quite careful enough with my reflector, and used a screwdriver to prise off the lamp holder. I cracked the reflector very slightly, but the crack is only on the outside luckily.
The strange thing is, the crack happened just AFTER I'd removed the bulb! It appeared to be fine, then a split second later, I heard a 'ping', and the reflector was then cracked slightly? It must have been thermal stress from when the lamp was working, and the bulb holder was keeping the original crack from growing.
I'll post a pic of the actual lamp in the next post. I doubt the lamp works (ballast is broken), but I should be getting a new lamp and ballast from the very kind ywh soon.
Here's a photo of the back of the reflector, you can just see the small crack to the bottom left of the picture......

Below is a photo of the bulb itself. You can hardly see the electrodes on this bulb. I think it's safe to say this one's broken, or wouldn't have lasted very long (if I could have tested it).
The bulb is the Osram VIP 273/46 and is still in it's ceramic holder...

My reflector is all scratched up inside on the reflective bit. I think the owner before me had a go at it. Is that going to be a problem once my new lamp goes in or is there any way I can repair the reflective surface?? I've never had it powered up as of yet or seen it working.
ywh said:
So is what I stated true?
Do these bulbs (the JYS and the JYD) replace the $300-$350 lamps that are usually needed forcommercial projectors?
What are some models that uport these bulbs?
Any clarification will greatly help.
Also, this question is not only for ywh. Anyone who has some helpful comments, please post or PM me.
Muffler mender
Well I got some muffler mender paste so I'll be appyling around the new bulb tonight and then let it sit for about 12 hrs. I'll have my first test of it by Monday evening so stay tuned...

Jawadali,
Yes, I have used the JYD to replace a commercial projector lamp using the original ballast in the projector...
I started with the 3M MP7750 and the 150W Jyd, but it was not bright enough.....actually that was not a surprise, I had measured 86VAC for the original lamp but I tried it anyway; the lamps are spec'd for 75VAC.
The lamp was also too big to go through the hole so I had to file it to get it in.
I ended up using the lamp in a Mitsubishi LVP-X70U..... Very impressive
brightness.
Just so you know, that is one hell of a lamp to take apart....The lens on the front is near impossible to get out of the way to remove the old lamp and get the new one in. I was lucky the reflector cracked and made it possible to do the swap.
What I am not sure of is how long these lamps will actually last, but at least I am enjoying my projector right now.
Something I have heard is that the reflector also has a lifespan but maybe someone knowledgeable in dichroic properties of materials may be able to shed some light on that.

Hi !OzOnE_2k3
dont bother the crack, we have used these crack reflector . it is nice too.
think you for your pic, I can see the bulb, there is a vacuum seal on the bulb.this is a mark of MHL,so I know VIP is MHL.
Hi ! Jawadali
I do this like: inject ink into Ink Tank for Jet printers, need some technique,like DIY projector lamp
good luk victor-eyd !

Hi ywh,
I don't think my last e-mail got back to you, so I thought I'd reply on here instead....
Yes, I would still like to buy the lamp and ballast please. If the total amount of $146 is OK, I will send PayPal payment to the diyproj e-mail address right away.
Thanks,
OzOnE_2k3.

Tougher than I thought...
The problem with the bulb is the part you screw the nut into. Its very tight just getting the nut to go in and ends up moving the whole bulb unit off the paste due to the force exerted. So now I have to start again but push the bulb back a bit further so I can grab the outer metal shield with my needlenose pliers while I screw it back down.
