Because that Amazon listing is quite recent.

Agreed, though.

Have you used this bulb yourself?

Here's a short video tutorial for replacing the bulb (or housing).

https ://you tu.be/v5Q8Dq-HRnk


I ordered a bare bulb from


I received it in a week (I live in Australia) and took about an hour to replace it. So far it seems to be working the same as the original bulb.

The whole mercury gas thing is kind of scary though... Am I mistaken or is it true that you can basically go insane if a projector bulb bursts near you?

I was about to buy it because my projector was showing the "lamp" light in red and didn't turn on. It's working again, so maybe it was a glitch or it will die soon. When it does, I'll buy it since it has good reviews. If others find a better price, let me know.

I just ordered it. Lamp is dying I think, even though I only have 2500 hours on eco.

Unfortunately that Amazon seller won't ship to Australia.

I found these two sellers, which one is real or fake I have no clue.

Is anybody here (from Europe) that can share experience about bare bulbs? Where you bought and how long lasts the bulb?


Reading different forums and many posts, I'm confused where to buy. I would like to find an original bulb (Osram), but how can I be sure... So, is there anybody who bought a lamp on this or that site, and lasts for x hours.


Thanks!

How'd it work out? Seller has 6 left, thinking of getting one.

Thanks!

I put it on SmartEco and haven't had any lamp issues since. I'll hold the new lamp until the old one blows.

I'm getting ready to replace the bare bulb in my W1070.

I watched a YT video and it said all the screws on the bulb housing are "small star screws," about 6 of them.

Are they Torx screws, and does anyone know the size? I'll need to buy a driver online. Or can they can be tightened/loosened with something else?

Thanks!

Standard star screws: much like what is common in other electronics (for example laptops, etc). The procedure is pretty simple; a YouTube guide is a good start.

Kinda like the left-most set of screw drivers here:
http://www.amazon.com/gp/aw/d/B008TM1910/

Interestingly, I have a few light fittings in my home that use the same screws.

Avoid touching the bulb itself with your bare hands where possible.

How any hours are on your lamp? (Using what lamp mode).

Thanks. I'm in Japan so I'm hoping I can figure out the exact thing/size and order it.

I'm at almost 8000 hours on my first bulb! I waited too long to replace it. It just started flickering and dimming yesterday. I did the first 4000 hours or so on smart eco then the last 4000 on economic.

Woah!! Nice.... If I hit that kind of lamp life the lamp might actually outlast the use of my projector itself!

A standard electronics star screwdriver set will sort you out.

Up until now: have you noticed major dimming?

Replace ASAP, though: sudden dimming is a sign of imminent failure.

The screws are very small and it's a 6-pointed star, right? Maybe I'll just go for a cheap multi-size Torx screwdriver set.

I'm viewing from 7-ft distance, so it's really bright XD which made the gradual dimming a good thing. Just yesterday it flickered about 6 seconds then went quite a bit dimmer. It's probably still good for movies but the PC screen looks dull.

I should've shopped for what I needed beforehand. Busy day ahead and now I'm worried about the bulb exploding haha...

Well you certainly got your money's worth out of it! Very cool.

So you're looking more for Phillips Star rather than Torx.
Basically there's a point in the middle, rather than a flat section.

Thanks guys, the bulb replacement went without a hitch.

I was used to thinking of phillips as a "plus" rather than a star so I didn't realize I had what was needed.

It was easier than I thought, so I'll be doing it again in the next 9,000 hours

A few days ago, my benq w1070 lamp exploded as well (running hours just under 3000 in smarteco).
Today, after leaving the housing outside for days, i dismantled the lamp from the house, cleaned it etc.
The explosion of the lamp left some markings on the glass, in front of the housing, as seen in the picture.There was also a large area of a white substance cause by the explosion there, but i got it cleaned up very easily.
If i replace a bare lamp, will these marking/scratches show up in the final image?
Is this just a plain glass, or a special one like borosilicate? It was loosely fit and held down by a metallic shield so i guess it doesn't contain any sort of optic lens. Maybe it's there only for protecting the rest of the projector, like the color wheel etc to get damaged by a possible explosion.
Budget is very very very very low, so i guess i'll go for the bare lamp. Maybe i can go to my local glass shop and have him make a replica of this glass if that is possible.

Capzor: how's your fake-as-heck bulb going!?

Just to follow up: at around 4200 hours, last week I decided to give this bulb a try since the original recently started getting a bit dim (I use it almost exclusively in brightest mode - SmartEco).

So I tried my cheap-as-chips non-original bulb (similar to yours ;-). I had low expectations (because it looks pretty fake!); so in my haste I didn't screw the housing into the projector because I wanted to quickly test it out: I simply plugged it in, secured it in place, closed the lamp compartment, and fired it up. And it was dim as can be. So I figured it was the cheap-and-dirty bulb. Immediately arranged an original BenQ one. It arrived today; and I did the same thing: quickly slipped it into the projector, didn't bother with the (silver) screw on the housing: and lo and behold: same abysmal brightness. Was only then that I realized that the screw is actually necessary to align the housing properly to the internal lens. (I promise I'm not normally this stupid...)

Fastened the screw, fired it up again, and voila: full brightness.

So I went back to this non-original bulb; put it back into the housing; placed it back into the projector - and tightened the cursed screw this time - and just like that, it's as bright as the brand new original BenQ one.

Go figure.

Here's a picture of the non-original and BenQ-branded lamp projecting the test pattern onto the same wall (both in full brightness modes):



Equally bright.


I'll still be keeping the original one (and I'll use it first); but I guess it's nice to know that the non-originals deliver the goods at dirt-cheap prices. Whether I'd get the same solid number of hours from a non-original bulb is debatable, of course.
So for that reason, I'd always recommend at least sourcing the original Osram bulb (ie: don't do what I did if you can avoid it) - the original model number of the bulb is:
Osram P-VIP 240/0.8 E20.9n
Since these Osram's can still be found really cheap (as per earlier posts in this thread), it makes sense to go this route.

Old bulbs had this model number printed; the new ones have it embossed/etched instead.

Yes, as far as i know the bulb is the same.
I haven't made up my decision yet. I'm waiting for more people to comment what they think about.
When i look at the glass at various angles, i see the surfaces somewhat colored. Maybe it's not just a plain glass.

The iridescent glass on the front of a projector lamp housing is especially coated such that it functions as a UV/IR filter. You can't safely run the lamp without it, unfortunately; it'll damage the projector over time...

The scratches on it will likely appear as dim areas (and/or colored fringing) on the image.


As an aside, Philips has an interesting paper on the importance of replacing a bulb with an exact replacement model (and this gets mentioned there as well):

I purchased this bulb:

http://www.aliexpress.com/item/Free-...825057615.html

I got it installed almost 2 weeks ago and so far so good. I don't know if it means anything but my original bulb had the Osram logo etched into it but the bulb I received had the logo just like stamped on. I can say that the new bulb was noticeably brighter than the one it replaced. The old bulb was still working fine and perfectly watchable but had dimmed some and since I had surpassed 5,500 hours on it I didn't want to push my luck and risk it exploding. If this bulb lasts a year I will be satisfied with it for the price.

Nothing wrong with that... They don't 'age' without use! I'm sure you'll get a solid lifespan out of it.

I can say that the new bulb was noticeably brighter than the one it replaced. The old bulb was still working fine and perfectly watchable but had dimmed some and since I had surpassed 5,500 hours on it I didn't want to push my luck and risk it exploding. If this bulb lasts a year I will be satisfied with it for the price.
i ordered the same one and received it today. the boxed bulb came inside another box with bubble wrap on all sides, imo the packaging was great. below are pics of what i received(the actual shipping box is not pictured). from what i can tell this lamp is genuine, perhaps old stock but genuine. the last aliexpress bulb i bought looks exactly like this and lasted over 5000hrs(still worked but flickered). i have not tested this yet, i will shortly but i am not worried. aliexpress actually has a very good policy regarding defective products and customer satisfaction.

i would say anyone looking for a replacement bulb for their w1070 should certainly give this a go, $42 is a steal.

EDIT: i decided to try this bulb out tonight after all. it looks as bright as i would expect from a new bulb, i had my original bulb(what came with the projector) running as a stopgap(it has about 1000hrs), this one is equally bright maybe more so. i included another pic, it is the backside of the bulb(in the housing) that came in box new with my w1070, as you can see it looks identical. i guess i got my w1070 before they started etching the osram logo in.

Ordered the same as biztyke (and chmcke01), got it a couple of days ago and it looks the same, except that mine come in just one box without any bubble wrap. Haven't tried it yet but thought i would share some more pictures for those who're curious.
