Well Iâve concluded after a lot of search that LED projector should atleast be 60 lumens, 500-1 to 1000-1 contrast and should have USB or SD card slot. LED projectors brightness level is somewhat better than the conventional lamp based projectors so anything in the range of 100 lumens in enough. Also the biggest advantage of 20000 to 30000 life hours :-D I am now a happy owner of 'Samsungs sp-p410m' LED projector which is absolutely brilliant. Couldnât find it online in UK so ordered one from Korea :p yep i liked it that much :p it has SVGA 800 x 600 resolution, brightness 170ANSI, 1000-1 contrast ratio and 80 inch projection which looks stunningly bright, vivid and crisp on my not so white wall. oh and it has digital keystone correction too :-D inputs are VGA, composite & USB. its around 750$ but worth the money as it will last for 10 to 15 years. I recommend following in order, but plz give specs a LONG good look:
1-Samsung sp-p410m
2-Benq gp1
3-Toshiba TDP-F10
5-Samsung sp-400
4-Acer K10
Please give your suggestions or share your experience.
Thanks

Led projectors are very dim... the dimmest on the market. Only useful in a very dark room, & small screen. Resolution is no better than DVD resolution or worse on most of them, except the most expensive.
Led projectors are nowhere near as bright as the dimmest lamp-based projectors. Typical popular normal projectors boast 1600-4200 lumens with a contrast ratio of 2000:1.
LED projectors are 10-60 lumens... About the brightness of a very dim penlight flashlight, & very poor contrast ratios. Brighter ones are just now coming out, but still not good or bright enough to be practical.
For the price, you can get a 1600-2700 lumen DLP projector with a 2000:1 contast ratio. They're small enough to fit at least 2 in 1 backpack.
I typically fit 2 small DVD players, mixer, a laptop, & 1 of my DLP projectors in a backpack.
LED projectors are a portable novelty or toy for those with a disposable income, & not really very useful or practical yet. Wait a few years for the technology to get better.
From my experience with super bright LEDs, & the specs on them, is they grow dimmer with age long before their "lifetime" is up. How useful will that dim overpriced projector be if it's grown too dim to barely be seen after 3,000-5,000 hours?
Notice the LED display on your alarm clock, DVD player or VCR has grown too dim in just a few years?

Can a projector make this size of image? Also, HD or SD?

I want to use a projector instead of a TV, because the only available space is above a radiator and I'd rather put a projector screen there than any electronics like the xbox 360.
The length of my room from wall to wall (from projector to screen) is around 9.5 feet. A bit less when you consider that the projector itself would probably be around a foot long on its own, so it might be around 8.5 feet from projector to screen.
I only really have space to fit around a 50-54 inch 16:9 screen including any borders though.
Can projectors make that kind of size from that kind of distance?
Would I notice the benefit of 720p in these circumstances or should I just stick to 800 x 600?
Answer
Ok, you asked several questions in one! The other answers are correct, but I'll try and make this specific and comprehensive!
First, what projector do you have? If you let me know, I can tell you what the throw distance would be to get a 54 inch image. Typically speaking, you can get a 54 inch image with about a 6 or 7 foot throw length, depending on your projector. You definitely will be able to get a 54 inch image with 8-9 feet of throw space. Check out the calculator in the source list for exact ranges of your particluar projector.
Your second question is would you notice a benefit with a 720p projector over a 800X600 native resolution. My answer is WITH OUT A DOUBT. I actually just compared a Toshiba DLP-S25U projector with a native resolution of 800X600 to a Panasonic AX200U projector with a native resolution of 720p. The difference was incredible!
A couple of issues with projectors, as well as HD TV's:
First, there's a huge difference between 720p with a 1200:1 contrast ratio, and a 720p with a 6000:1 contrast ratio. The reason for this is because the picture sharpness and detail is all in the ability of the projector or TV to display different amounts of shading. The contrast ratio is how many shades of grey are between white and black. To get the best HD picture, you need a contrast ratio of at least 5000 or higher. Newest TV's/projectors now are 10,000-15,000:1 ratios!
Keep in mind that 720p means a native resolution of 1280X720. This means there are 60% more lines of resolution over 800X600 picture. That is truly significant! Is it life and death to upgrade? No. But if you see what 720p looks like, you won't be able to go back to 800X600!
As someone who has purchases many projectors and used them from my own home theater, to large auditorium settings, I would recommend you get a projector that has a 1280X720 native resolution, also known as 720p. Don't be fulled by projectors saying they are HD but have a native resolution of 1024X768. They will say they are 720p/1080i capable, but what it means is they can receive an input at that resolution, not that they can project at that resolution.
I would also want a projector with at least a 2500:1 contrast ratio, and would prefer 6000:1 or more. If you want to truly see the ability of HD, then you need the high contrast ratio.
Lastly, get a projector with between 1000 and 2000 lumens. I wouldn't go under 1000 in case you need it in a bigger setting at some point. Anything over 2000 would totally wash out 54 inch image and not make a good picture. I personally can recommend the Panasonic AX200U projector. It does an amazing job. It's 2000 lumens on full bright, but has an economy mode which takes it down to 1700. The contrast ratio is 6000:1, and it has a zoom lense of 2x, which is far superior to almost any other projector! Basically, from 8 ft away, you can have an image that is 40-80 inches, or anywhere between.
You can buy a brand new one on Ebay for $1250. I have used it in a small setting (about 60 inch screen), and just used it to broadcast the BCS National Title Game earlier this month on a 138 inch screen! It is a phenomenal projector for the price! Good luck!
