Meldrew Posted July 13, 2012 Posted July 13, 2012 Hi, We've been asked about the feasibility of setting up a couple of projectors for use outdoors for an assembly and I wondered if anyone had any experience or information about it. To give you a little background, at the end of every term, we do a whole school assembly where prizes are given out, the band plays some songs and the dance class performs something or other. A big part is 2 large projected images on the wall in our games hall where we show photos of events from the term and pick bingo prizes from a scrolling list of names of students(number of entries based upon the praise points students gained in the term). Some bright spark commented to the principal how wonderful it would be to have all this outdoors (depending on the weather). I've given my opinion that the image will simply not be visible outside as our brightest projector is 2200 lumens. Does anyone know how bright a projector would be required for outside use? Obviously it depends on quite how bright the ambient light is, so I'd say fairly bright as if it was dull day chances are we'd go back to our games hall. Any input gratefully received!
rad Posted July 13, 2012 Posted July 13, 2012 I was asked if it is possible to get a projector outside for sports day. I said no chance. I would be more inclinded to speak to a projector/tv hire company and ask their thoughts/get a price. It would be nice to show, but I dont think a normal classroom projector will hack it.
broc Posted July 13, 2012 Posted July 13, 2012 (edited) I wouldn't bother. We have a couple of break-out areas indoors at my school where projectors were installed. There are tinted glass skylights overhead and on a normal school day they are almost unuseable. Also, I did some work with another school a year or so ago where they have an auditorium with a glass roof; they asked for a projector in there, their AV supplier advised against it but they insisted. They put the most powerful projector they could find (it cost them £20k) and it was still almost useless on a bright day. You have no chance against a 6840000000000000000000000000 lumens light source! Edited July 13, 2012 by broc
broc Posted July 13, 2012 Posted July 13, 2012 Aren't LED screens generally considered brighter than Plasma? However, if they are anything like viewing a laptop, smartphone or iPad screen out doors forget it!
Meldrew Posted July 13, 2012 Author Posted July 13, 2012 Hi, We've tried LED screens outside before (a different bright spark this time). We even purchased gazebos with sides to try to make the screen visible and it was a waste of time. BTW, the event that we have to setup for is a week today (just got told yesterday afternoon).
sonofsanta Posted July 13, 2012 Posted July 13, 2012 Heavens no. You won't see anything unless it's a particularly dark and cloudy day, and if it's a particularly dark and cloudy day you probably don't want expensive electronics outside. Covering a projector with a tarp is a bad idea given the heat output as well.
Fazza Posted July 13, 2012 Posted July 13, 2012 Unless you have an exceptionally bright data projector then most likely you wont see a thing. To prove the point, take a projector out side at the brightest possible time and then take a few photos of it and get some staff out to take a look too.
twin--turbo Posted July 13, 2012 Posted July 13, 2012 We wanted projection in our atrium, but ended up with a 104" TV instead, smaller but it's visible in all lighting conditions. Rob
Oaktech Posted July 13, 2012 Posted July 13, 2012 you need monster projectors to work outside. What you need is these guys... Fonix LED :: Mobile but they don't come cheap. I would tell the powers that be that unless they have thousands to throw at it, to can it, it won't work.
Chris_ Posted July 13, 2012 Posted July 13, 2012 We've used a 40" plasma once for displaying the tennis outside, that was in the summer, in a bit of a shaded area, perfectly visible. Another time we've used a 15,000 lumens projector to display some presentations outside. It was ok during the day (much better at night though), although it was a pretty overcast day...
Marc-Engineer Posted July 14, 2012 Posted July 14, 2012 Your projector would have to be around 9000 lumins on a normal day and the screen would have to be shaded. Marc Projector Engineer
SYNACK Posted July 14, 2012 Posted July 14, 2012 Think about drive in movie theatres, they only work at night and they have massive projectors. You have no chance during the day, even with a mental projector.
m25man Posted July 15, 2012 Posted July 15, 2012 Find the fuse for the sun and pull it out.... or rent an LED wall from ADI Choose your Big Screen, Mobile LED Screens, Event Screen Selector - ADI.tv They look after my Jumbotron and have a solution for all requirements.
twin--turbo Posted July 15, 2012 Posted July 15, 2012 Could wait for the next solar eclips, or fudge NTP and everyones watches by 12hrs Rob
