There are several available on Aiiexpress

Non original bulb

http://www.aliexpress.com/item/BENQ-...282728409.html

Original bulb

http://www.aliexpress.com/item/origi...906390398.html

Both come from china. The price of the non-original compatible lamp is half the price. Might be worth trying at that price.

Good find! I thought these had dried up.

I would definitely get the 70 dollar one. It's not like 70 bucks every three years is a big price to keep a projector going.

Rwestley,
Those two bulbs you linked to (thank you) have different average life expectancies, as predicted, the less expensive one is rated at ~2,000 hrs. the more expensive ~3,000hrs. The more expensive one CLAIMS to be original OSRAM manufacture, who knows for sure. Considering the amount of work involved in replacing a lamp, the inconvenience, and hopefully not a broken bulb with loose glass, I'd put my money on the higher priced bulb. But then again, who knows for sure.......
Just to confuse things even more, here's another bulb listed.
http://www.aliexpress.com/item/Origi...ck_to_detail_a
Could someone who has actually seen the back end of the ORIGINAL bulb please give us some feedback details of the OSRAM stamp / markings. This bulb also claims it's a "9" and not an "8".


Ben with the screen issue,
Your solution is to move the screen down, away from the ceiling. Ceiling reflections wash out the dark portions of the screen and make everything look Blah.
I'm trying to talk the wife into letting me put some black velvet on the ceiling for reflection reduction. Sounds kinda kinky!

I probably would take a chance on the $35 lamp since who knows if the one for $70 or $75 is an original or just a knockoff with the Osram name on it. I would probably order a few to have an extra one on hand. At these prices it is hard to go
wrong. The one thing I would be sure of is that it is rated at 240V and has a 9N as the last number. The 8 is a different lamp.

The model number displayed on the bare bulb used in the official housing (at least mine) is:
Osram P-VIP 240/0.8 E20.9n

Here's a pic of the bulb in the housing with the model no visible:

Thanks for all of the help with the screen/mounting issue guys! Based on all of the advice, I have decided to ditch the old TV stand and to go with a component cabinet in an adjacent storage room instead. This way I will have a lot more flexibility with my screen size and positioning. I'm still going to go with a 120" screen, but now it will be a foot from the ceiling instead of just a few inches.


So, yet another w1070 placement question: if 3" is the smallest distance from the projector to the top of the screen that I can get away with using the BenQ w1070, what is the largest distance? I already purchased the projector and I picked up a Chief RPAU mount. So I'm just trying to figure out what kind of extension, if any, that I'll need for the top of the screen to end up about a foot from the ceiling.


Thanks so much!

Based on the quoted offsets from Ftoast previously in this thread:

A 120" screen is 58.9inches tall. 5% of 58.9" is 2.95inches.
I would say the largest distance would be 58.9" * 15% = 8.84 inches.

Hello, I am new to this forum and I am pround owner of Benq w1070

I am using it a lot .. really a lot (i made around 1300hours in 6 months) and now I am allready thinking about new lamp (sooner or later I'll need to buy it) but online I saw replacement bulbs and replacement moduls with bulbs.

What is the diference? Can I replace bulb myself? Can I replace module + bulb myself?

Is there maybe any "how to" replace this?

I assume that I would find this answers in this topic .. but it is 370+ pages long

Thank you
A.R.

I received my W1070 today and I haven't had a chance to setup a screen or mount the projector. Even with it displaying on a wall and part of my t.v when I tested it out, the image is pretty damn good for the price. I actually could see it replacing my ST60 as my main display if it weren't for the mediocre daytime viewing. The only two things I've noticed is my Comcast content displays fine but all the words are reversed and sound from my AVR sounds...Hollow? I'm not sure if I need to calibrate the 2nd HDMI output or not. It could also just be the broadcast. I'll try some other content.

Woot has the W1070 on sale for the next few days for $570 with $5 shipping bringing the total to $575! I'd post a link but I don't have enough community posts to do that yet. Just go to Woot->electronics->garage sale and its listed as the BenQ 2000 Lumen 1080p Home Theater Projector

The only things you need to be wary of is the unit is refurb and rather than the standard year warranty, it had 90 day warranty but this is still a steal for this great projector.

Pleasure, man. It was actually a shot I took a year or two ago when ordering my spare from a local AV supplier. Like Dreamer warns above, they managed to send the wrong model and I needed photographic proof to that effect. (They did sort me out thereafter).

Agreed. Seller reputation needs to be good and it makes sense to ensure refunds are accepted. And even then, it's a bit of a gamble. But that price... Man, that's just plain dirt-cheap when the bulbs for this model are known to remain nice and bright for 4000-4500 hours plus (in SmartEco mode). That's 3+ years of use for most people; at (effectively) full brightness.

Man, right when I'm ready to buy. But that refurb/90 warranty has me worried.

Is there a way to see hours used and a way to tell if a unit has been calibrated? Since I bought mine used I'd like to know how many hours the lamp has been used for.

If you dig around in the menus, there is a display for "equivalent lamp hours" or something like that. I'll dig around and see if I can find a photo of it, or I'll take a photo of mine when I get home tonight.

EDIT: Here's a photo I found on the tubes:

Thanks! And no need to go through the trouble if you weren't checking your's anyways . I'll dig around today and once I find it I'll post the pic for future reference.

Apparently it only has 5 hours on it. Not bad for a used one!

I got the screen set up and unfortunately it doesn't pull all the way down in front of the t.v. I'll have to get some lower hanging hooks for the ceiling. I'm going to wait to ceiling mount the projector until the 120 inch screen comes in. I'm really torn on 16:9 or 2.35/2.40. I put Star Trek Into Darkness on and the black bars were definitely noticeable on a 16:9 screen. but I'll also be doing some gaming. A screen with masking is out of budget.

Has anyone done a ArgyllCMS calibration on the W1070?
I am not sure what my result numbers are yet but so far the best I have seen is %90 Gammut Coverage. I am waiting for feedback from the ArgyllCMS thread next.

Good choice on the equipment relo!

So, here's how I do it. Mount your screen. Mount it at a height you like, make sure you are comfortable with the height and that it's level and all the rest.

Now, grab a ladder, a friend, maybe a few books, and an extension cord. Flip the projector over, power it on, bring up a full screen image, and take the projector to the top of the ladder. VERY CAREFULLY! All of this is very low tech, but works very well. Adjust the lens shift so it is maxed out, dropping the image as low as possible when the projector is upside down.

Now, raise the projector up until the image is really close to square with the screen and fills the screen and has no visible angle or anything else. Have the mount on it and everything. Now, measure from the top of the mount to the ceiling. Add half an inch, and that's how long your extension column should be.

Run over to Home Depot, grab the tube in the length you need, head home and mount it.

Very custom, relatively quick, should be accurate for the mounting as long as you take your time and are careful. I sometimes use books to perch the projector on so it is a more stable base to measure from and make sure I have things right.

i know this projector can do a lot of sizes with no problem, but is their a size that just works really well. Also is their a screen that works better than others. I am ready to pull the trigger on one but I am up in the air about which screen toget. This will be my first attempt at a projector and I am basically doing a rough in to see if I like it.

You'll want a standard (cheap), gain-free (ie, gain of 1.0), fixed-frame, white screen under most circumstances for this projector. Preferably a well-reviewed one.

A few years back I started with it at a 100" diagonal image; swapped to another wall (upon which I ended up using 110"); and about 6 months ago (when finally ceiling-mounting) I made a last-minute decision to push it up to 127".

I found that at 100" it was actually a bit too bright for lights-out viewing (even in dimmest 'Eco' mode - though I switched BrilliantColor 'off' to tame brightness).
110" was better.
It now handles 127" in Eco mode (switched BrilliantColor back on) very nicely in the dark; SmartEco will take you way larger. We use SmartEco at the current 127" size when we want ambient light about (social gatherings, etc). @AV_Integrated drives a screen of over 160" diagonal without issue.

My recommendation? Don't order a screen at the same time: start by getting a feel for what size works for you by projecting onto a plain (preferably white; or light-in-color) wall and viewing for a few weeks; once you've worked out what size provides the ideal immersion for your room - then you commit to a screen.

From memory, it's between 2 and 3 feet above the floor.

Aim for having the center line of the screen reasonably close to eye level when seated: typically, you want your eyes no lower than a third of the height of the screen (when measured from the bottom of it), such that you're not staring upwards at the screen, which is tiring on the neck. Think of where you normally sit at a movie theatre to get an idea of what would work for you.

So, here's how I do it. Mount your screen. Mount it at a height you like, make sure you are comfortable with the height and that it's level and all the rest.

Now, grab a ladder, a friend, maybe a few books, and an extension cord. Flip the projector over, power it on, bring up a full screen image, and take the projector to the top of the ladder. VERY CAREFULLY! All of this is very low tech, but works very well. Adjust the lens shift so it is maxed out, dropping the image as low as possible when the projector is upside down.

Now, raise the projector up until the image is really close to square with the screen and fills the screen and has no visible angle or anything else. Have the mount on it and everything. Now, measure from the top of the mount to the ceiling. Add half an inch, and that's how long your extension column should be.

Run over to Home Depot, grab the tube in the length you need, head home and mount it.

Very custom, relatively quick, should be accurate for the mounting as long as you take your time and are careful. I sometimes use books to perch the projector on so it is a more stable base to measure from and make sure I have things right.
Thanks so much for this! I have been trying so hard to get measurements exact and to plan everything out perfectly, and it never occurred to me to try a more practical and common sense approach to getting everything setup. I really appreciate you taking the time to write all of this up, I'm sure it will save me a ton of headache in the next few weeks!

It will. I did the same thing you did, and I still typically measure things 100 times over, but when it comes time to hang the projector, before I actually cut a hole or mark up the ceiling for holes for hanging, I always just bring the projector up, set it on a ladder, and make sure that my own stupidity didn't get the best of me. Since I do installation work, I do carry several lengths of pipe with me on jobs to hit the drop I typically need, but I've done the same where I've gone out, bought the pipe, painted it flat black, then installed it at the end of the day, or the next day.

It's so fun, and so exciting, but taking your time, especially towards the end, is the way to go.

I haven't read the whole thread. But from the last few pages I was wondering if I should be running it in Eco or Smarteco mode? I normally run in it in Eco to get the most hours out of the bulb. But if i'm going to get the same amount of hours by running it in SmartEco maybe I should run it in that mode?
