Suggestions on Short Throw, 200 inch, 3000+ Lumen Projector?

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.
