Ah, thanks for clarifying. That $245 is a scary number, and seems disproportionate to the total cost of the projector. With an older W1070 whose fan bearings rattle in a pretty pronounced way, that might almost be sufficient impetus for an upgrade. Fingers crossed the current bulb hangs in there for a while yet!

Yeah, with that price for the bulb you could almost justify just replacing the entire projector each time instead of the bulb, lol! You can pick up a 1070 for around 500.00 now. If there's any drop in lumens with my cheap bulb, I certainly can't see it. If it's dimmer, it's not enough to worry me.

The high price of projector replacement lamps is one of the reasons why some are attracted to Epson and their lower cost lamps for many models. It's also what drives some to LED models even though LED has so far not been able to match UHP lamp brightness.

So with a 245.00 bulb, and if we use 4000 hours of use as an example the cost per hour comes to roughly 16 hours of use per dollar. I actually had less than that on my original bulb around 3600 and I used eco, I know some have posted longer times, just didn't happen for me.

So right now I'm at approx 1550 hours and I paid 43.00 about 8 months ago (that same bulb is 54.00 now) so I'm at roughly 36 hours of use per dollar so far. I would need at least 700 hours based on 4k hours use to break even. I bought a replacement bulb when I ordered my projector back in 2015 and this was before I really did any research on genuine vs generic and I paid around 165.00 for it and I wished I had just waited, but too late now. I used it for about a month and then pulled it for the Maxi cheap replacement to see if it would work. I wrote the hours on it and stuck it back in the box. I don't know if that bulb was genuine or not, I think it had the Osram logo or whatever it was, I forget. But I never noticed any difference in quality or brightness, granted I have this in basement with walls painted black and usually don't have much ambient lighting but I didn't before either. Only difference is I paid 122.00 more for the first bulb and it may actually be a knock-off too.

Yes, it's a low-cost projector, I could see paying more for the bulbs if it were a $10k or a $5k PJ, but it's not. It wouldn't surprise me if the 245.00 bulb you're ordering is indeed a knock off too, they're all made in China.

You can get a counterfeit lamp at any price, though most counterfeits are sold at unrealistically low prices. Most are made in China and counterfeit products are rampant in China which has poor consumer protection laws. There are counterfeit Rolex watches and Coach purses that have Rolex and Coach logos on them. Just because a lamp has Osram stamped on it doesn't mean it's the real thing.

The best way to be assured of getting the real thing is to order it directly from the projector manufacturer or from a trusted vendor with a strong reputation for only dealing in genuine OEM replacements. The reason that there are so many different companies selling a specialized product like projector replacement lamps is because they can make a quick buck selling to uneducated consumers.

I thought Benq no longer sold the bulbs on their website. Finding a trusted vender these days would be near impossible, many legitimate websites sell the knock-offs too giving the customer the choice. I buy the cheaper bulbs simply because they're cheaper. So far I haven't noticed any difference in quality which says something about the exuberant markup prices for these bulbs that manufacturers want their customers to buy. It's very much like ink for printers, they don't make much on the sale of printers but they do on the ink.

BenQ is still selling genuine OEM replacement lamps for the W1070:

benqdirect.com/replacement-lamp-for-w1070-w1080st.html

If you think you can get the same quality much cheaper, go for it. The cheaper they are the bigger the gamble. Some have had good luck and some have had disasters. Millions of people gamble in various lottos and casinos every day. It's only money.

For some of the old dvd players, you had to go into the setup and turn on the hdmi port.

I think if the projector was a $3k projector or more I wouldn't take a chance on a knockoff. Not worth the risk when you have that much invested in the projector which a non-genuine bulb would void your warranty at least for as long as that warranty was good. A cheap projector like the 1070, it doesn't bother me. It can be replaced for $500 anyway. Since they have a 30 day return and 180 day warranty on the bulb that would get you past a defunct bulb, most likely they would go bad in the first 250 hours of use as some have reported. I was thinking about picking up another 1070 just for backup and keep it in the box.

My experience with the 1070 in a few lines:

Great projector, nice colours, bright and very good video quality, no tearing or other issues.

Few things to note, I do sometimes get the rainbow effect, only slightly noticeable, not a big issue at all.

The projector is a tad bright, i've not adjusted the settings at all but the original colour config is fine and I dont know where to start with adjusting it. We generally use it on a white wall, and the blacks aren't very deep at all.

However we got a 150" grey projector screen and the colours look brilliant, so much better than on a white wall, the blacks are now deep and overall picture quality is so much better.

Little update. I've found the perfect spot to slide this filter in / out without touching the colour wheel (which is fragile + heat and vibrations will break up this filter easily).



The ideal spot for this DIY filter is between the exit of the collimating rod and the relay lens at the entrance of the optical cavity.

Yes, I had to literally take apart the entire projector to get to it. And I first had to cut a new mirror and test that (it works, phew) so I don't have the WCG filter installed right now, but I will soon. It'll be removable with a screw from the bottom of the case. The good news is is that my projector's image is perfect now, I cleaned everything including all the internal lenses and mirrors and DMD, and the lamp is actually good and bright! So scratch what I wrote before.

If I don't buy a new projector this year I believe I can mod this one into a new case and make it permanently quieter and possibly even do a contrast mod + replace the lens for a longer throw. Then I can use my anamorphic lens and wider zoom at the same time. (to actually benefit from higher lumens). Then I can also think about watching UHD Blurays via an Oppo 203 with anamorphic stretch at 4K and downscale it to 1080p from an HD Fury Linker, or just watch it from my PC. Of course what I really want is quiet + WCG + contrast mod + higher brightness (different lamp, at least 3000-4000 lumens possible) + quasi HDR. This is quite a little piece of kit and I know it like the back of my hand.

I can take it all apart and put it back together, from memory, really quick and fully functional. I also now like one of the other designs I saw before, with a grayscale 1080p LCD with high transmissivity: basically put that on the outside of this projector. So use just an LCD panel + HDMI board as a "relay projector". The w1070 wouldn't even need to be opened or modified at all. Instead of putting an anamorphic lens in front of the w1070, you could put another light modulator to achieve 1M:1 contrast ratio.

And then get the best of both worlds: DLP motion handling combined with mega contrast, WCG...and eventually HDR10 with some custom shaders via PC playback at least. And of course that's without even going into the idea of using RGB lasers or LEDs to retrofit the light source. Rec 2020 lasers are definitely do-able although I'm not sure how expensive it'd be to get lots of lumens out of it. I think the price of green lasers should come down soon so DIY light source upgrades should be possible.

How can you do that when RGB light sources wouldn't use the color wheel?

Turning on / off LEDs or lasers sequentially is a trivial matter for any arduino or raspberry pi kit, or even just an analog wave generator to turn them on (with adjustments for speed + phase of course).

It's nowhere near as good as what actual LEDs can do in terms of colour wheel speed though, since they can do all kinds of colour timing patterns to get rid of rainbows and increase effective colour wheel speed tremendously. But it's a start. And at least, it would simplify cooling greatly over a traditional lamp. The blower fan would be gone, which is, now that I got a new lamp back in there, a real nuisance once again. Might have to put the ol' unit back in the hushbox I made.

All of a sudden my BenQ projector remote will turn on the projector but when I try to switch the remote info button it will not move at all, the batteries are new and never had this happen to me before, any thoughts or has any one experience this? A Little help would be appreciated.
