I have some ambient light coming in my room too, even after putting up special shades and light blocking curtains over the windows. However, this projector is bright enough to overcome that and by a considerable margin. I believe it could be even brighter in the room and the 6030 could still throw a good picture. To get a much brighter projector you would have to spend quite a bit more money as the Epson is one of the brightest mid-range projectors. It looks fabulous shooting on my Carada BW 106" screen. If you plan on shooting on a much larger screen that will have to be taken into consideration but the ambient light I receive has little effect at all on 106".
I paid $3500 for it through a local dealer (I think Amazon's price is even higher). I have installed my own projectors in the past but they would bring it out, install and set up for only $200 so I thought it would be worth it - and it certainly was. They did a great job (btw, this projector is very heavy and it was a two man job). I'm 66 years old and just felt it would be safer for both the projector and me to have them do it. Plus, if there was any problem with it they could bring it back and give me another. It just saves a bunch of trouble and work so that something you might consider, as long as the dealer is reasonable. Remember, you get an extra bulb, 3 year warranty and a great mount (I think it might be a Chief) with this projector, along with a few other features that make this projector a little more expensive but still a value based on performance and these extras.
Something else you might consider is professional calibration. After I had about 150 hours on the lamp I called in one of the best calibrators for both this projector and my audio system. Yes, it was expensive too but what a difference! I have great equipment including Yamaha Rx-v777bt, Salk custom speakers, Oppo, Darbee, etc. and prior to calibration I was getting half their capability. Now I have a system that I could not be more pleased with and is tweak as well as it can be. The calibration might be able to bring out a bit more fl output, even in Eco lamp mode, as it did mine, which should further help in your situation.
The only reason I'm saying all this is that getting a good projector is the easy part these days - most of the major brands are excellent. But once you do that you are only half way there. Getting it right for your room takes time and expertise and is the much more difficult part of home theater set-up. Good luck and let us know how it turns out for you.
