Who has the most lumens from their projector and how was it accomplished? The reason I'm asking is we are ready to build a very bright LCD projector and I was thinking about two or even three MHB for the job. This projector will be for my church so the size and brightness will be important. I would like to hear your inputs and advice.
Thanks

If you're planning to use it during service, it will be VERY hard to get a nice working setup for a church via DIY.. your best bet is to get a commercial projector.
If it's in *complete* darkness.. then any of the designs will work adequately I suppose.. but I would recommend a commercial projector.

Combinding the light of more then one bulb is going to be a major issue. However MH bulbs can be had as high as 10,000 watts. You WILL need to watercool such a setup. All and all I would say DIY is not the way to go on this one.
I think the lights will be turned down during the presentations and I was thinking about having the light on the top of the box and then having the screen and projection underneath to keep the heat up and away from the LCD panel and electronics.
Keep them coming and thanks.

agreed
Yea I would tend to agree with the Idea of Buying a prebuilt projector if your say using it in the sanctuary( where lights are on) vs using in say a classroom where lights can be turned off or dimmed. Look online for the deals, Not sure what Lumen output your looking at for a fully lit room But over 1,000 is a rough estimate. Good luck on eather way you decide to go, if ONLY LCD"S were as transparent as say a clear transparency, average overhead projectors would yield a great result But LCD's just eat too much light.............waiting for 15-20 years when we have something like video wallpaper or something.......now that will be cool

By the time you installed cooling systems and what not, your projector would probably cost more than a commercial projector, and not look as good. Commercial is definetly the way to go. There are no diy setups as of yet that are as bright as you want.
you will definately need a projector that pumps out more than 1000 lumens for a church. if there is no total light control then i figure you'll need a pj pumping out 2000-3000 lumens. depending on screen size. bigger screens require brighter pjs.
Or if lighting is a problem disable the light in front of the screen( of you can) like if you have MH lights lighting the room experament but I am thinking you would be better served By a pre built projector.😕 😀
I think heat will be a factor but nothing that can't be over come with proper air flow. I'll let everyone know how it turns out.
i should have known better than the old ladies playing video games on a projector on sunday.
if you are currently in the vatican i would advise 10000 lumens, if you want a image that creates enough light to diplay through a lcd with a bedroom-bright area a image of 3 meters by 2 meters i recommend 2200, or good use of a 400w bulb... and for anything larger, 3500 should be able to do 5 meters by 3 meters while shining through an lcd. for normal transparancies 250w is probably ok and 400 w is good. there are surely some educational guides as to dimensions.

We auditioned many commercial projectors for our church up to £40,000 Barco's.
After much testing we used the following in a room about 70ft x 90ft in size.
12ft x 12ft matte white screen
Sanyo XF10 3000 lumens LCD projector
Natural daylight was entering the room through windows and we got a good image, but anything below 2500 lumens was a waste of time - especially if you show video, or are not careful about what fonts/colours you use in your PowerPoint presentations.
Out of interest,if you do go down the commercial route it may well be cheaper to buy two 1500 lumens pj's and piggyback them, rather than buy one 3000 machine - also it leaves you with two projectors available to be used at other times - i.e. one for your youth group, and one for your seniors, etc...
just my two cents...

piggyback option is a good one but you have to consider replacement lamps. when the time comes to buy lamps you'll be buying two, which will be a small fortune, depending on pj.
