Hi everyone.

We need a short throw projector with the following specifications:

Screen Size: min. 200 inch
Brightness: min. 3000 ANSI Lumen
Distance Ratio: max. 0.6 : 1

Any suggestions?

P.S. I've found one: Optoma W316ST. It has very nice specifications. However, most people say Optoma projectors have very bad lamp life. So I'm hesitated.

I would want to know what this is for?

For home theater, a 2x color wheel projector, with weak color brightness isn't ideal.

For a darker 'display' type setup, then the 3,600 claimed lumens, which are more like 1,200 calibrated lumens, are likely fine as long as it isn't overly bright.

200 inches is far larger than typical. So, you need to go in knowing you are well out of spec. for cheap projectors, and if you want to go cheap on a projector, then you have to control the environment and accept the hit in image quality.

If you have almost any light in the room, it will wash out the image.

If you don't have a VERY flat projection surface, the image will be severely distorted.

There are very few short throw projectors which can handle an image larger than about 100" diagonal, so the Optoma is a good choice.

I wouldn't worry about lamp life, this is a normal wear and tear item and needs to be budgeted accordingly. I have never heard real reports of Optoma, or any other manufacturer, having significantly shorter lamp life than anyone else.

Lamps fail over time.
Lamps dim over time.
In a completely dark room, you want about 15 lumens per square foot of screen space, AFTER CALIBRATION.
In a normally lit room (no sunlight) you want a minimum advertised 80 lumens per square foot of screen space.
Real world contrast in a dark room may be over 1,000:1.
Real world contrast in a lit room has a goal of about 12:1
Manufacturers lie constantly, and their specs are rarely accurate for brightness or contrast.
If resolution matters, this is a 1280x800 projector, so a 16:10 projector... What screen size do you have? What aspect ratio?

Thank you very much for your detailed reply.

Actually, I want this for a normally-lit room (indoor).
The size of the screen would be 3x4 meters. So the aspect ratio could be changed from the settings to 3:4.

Are there any other short throw projectors that can provide 200 inch displays?

Not in short throw on any realistic budget. Your screen is over 100 square feet which is far larger than typical, and your budget needs to deal with that right now, or your results will be severely lacking.

80 advertised lumens per square foot to achieve a 10:1 to 12:1 contrast ratio. That's all you are going to get, and it will cost you.

This would be my starting point projector.

It isn't short throw, but it may be bright enough for your needs.

If you have a $10K+ budget, Panasonic also offers a ultra short throw lens which fits some of their better projectors. The lens is about $3,000, but can fit on their 6,000+ lumen projectors of a certain design. Not sure if they make one for the model I linked to.
