where do i buy the lamps? web address?

so where would i buy my replacement lamps? I assume i have a DC lamp. you can look at the photo above.
the model number is L120 to go in a Proxima 5800 desktop projector. also, how do i install the lamp in my reflector, i never done this before. it looks like it was in plaster. would i need something to replace whatever it was in? i'm assuming it's to transfer heat? bare with me i'm new with this.

Yes I noticed the prior post from pfloydphan & ywh and it looks like most of your questions are answered there.
Is your lamp burned out ?
I have three projects going , I have removed the bulbs from the reflectors on them and am awaiting the bulbs I have coming in for them.
Most all the information is covered in this forum in the replacement procedures..
If you are looking for a back up bulb and reflector module all in one, you might want to search around for one on eBay but eventually you will have to go the route of removing and replacing the lamp itself in the reflector as you never know what you will get on there..(eBay)
 
I assume you mean to pull the bulb from the reflector?
Some have mentioned that you soak the lamp bottom down in enough water to cover the white cement.
Let 'er soak for a few hours and take a small jewelry size screwdriver and use it as a pick to slowly work your way around the bulb from the backside.
I myself used hot salt water , not by anyone's reference but I just thought that being salt breaks down alkaline in cement and if there was any in that type .. Oh well , anyway it works . It's a slow tedious process without breaking the reflector, pick some away , re-soak for a while , pick some away etc..
 
eh too bad i didnt know that before i did it the hard way... i made a tiny chip in the very back of my reflector, i hope its not a problem. its not structural or anything, just a sliver. but i would need instructions on how to put a new lamp in the existing reflector, like do i have to solder anything and any tips you may have, besides not to touch the bulb or reflector! i'll use latex gloves.
 
From what I've read on here, and what ywh says I wouldn't sweat the chip.
One of mine has a crack in the reflector, he says as long as it's not through the silver I'd be fine.
Here's a pic of what I was talking about , I was able to wiggle the bulb out after it softened up ever so slightly might I add.., but was moist enough to allow the bulb to come out.
Much easier to get the rest of the cement out.

As you can see in the pic that bulb was originally off center , I've read that centering it is important to get even light output.
Notice the crack and where it is in comparison to where it was slightly off center?
I was considering digging about 3/4 of the cement out and using the little left as a guide , but not going to after checking out that crack from heat.
I'm still tweeking around in thought on how to center it , I've researched the cement available for these type applications and most are able to speed curing by about 200 degrees of heat.
That would help , I'd just use my heat gun., but if you have no heat gun , I suppose a blow dryer would work.
On the soldering thing , I'm just going to use crimp sleeves , solder might melt ..
 
Ok, right i see what you mean. i'll do that to get the remaining bits of cement thats on there, but my reflector is in great shapes, i guess i'll rub it down in alcohol to get my finger prints off, i wiped them off with a paper towel but i know how sensitive halogens are so these must be even more.
