Long throw projector?

[mrbios]

I'm after a good projector for projecting from 14-16feet away, the teacher is a bit fussy and wants to project it on to a different wall to the standard wall, we don't want to move the mount due to the fact that we'll only end up moving it back when she retires and another teacher goes in there (silly situation really)

 

I was considering one of the 20,000hour bulb life Casio projectors, anyone have any experience of these? Or any others you can suggest that might fit the requirement a bit better?

 

Thanks

Wow! hahaha... i had a look at long throw projectors and found them to be so super expensive that it just was not feasible. I realize for the most part we are "slaves" to the teaching staff, but in this case i think i would reserve my right to tell them to take a hike or pay it out of their won budget!

Luckily they are paying for it out of their own budget Though obviously the price needs to still be reasonable, what sort of prices did you find?

 

The distance i'm after is on the border of the throw distance capabilities in regular projector spec sheets (i think) so I was hoping just a beefy normal one might cope?

I can't remember the model, but I borrowed an Optomo that had a fairly long throw.

 

However you need to consider that the further away the projector is the more likely it is to shine in her eyes. If the room's got a high ceiling you'll probably be fince since you can mount the projector higher to get it out of her line of sight. However if the room is lowish then you might be in trouble.

Yeah Well this particular quote was for a long lense throw projector about 2 years ago, to go from one wall to another wall of a "Hall with a silly high ceiling". They wanted close to £10k for it, which we felt was not quite "On the money" so to speak, but to be honest i never followed it up, so the quote could have been a rip off

[mrbios]

LOL I take back what i said when i said "The one i'm looking at is on the border of the distance i want" ........ i was reading the measurement on the PDF as feet when it was displayed as metres, the casio XJ-M140-155 (4 models) will all be more than enough. Just got to persuade them to spend £700 on it though, granted the 20,000 hour bulb life should make that easier.

[RobBaxter]

be carefull tho, in order to maintain the aspect the projector normally speaking must be correctly squared. (don't ask) but i had a right little nightmare with 10 projectors which all had to be re-installed and aligned. Doh!

You'll shop around for the best price, take delivery of it, get it installed, get it keystoned and aligned, tidy everything up and pat yourselves on the back for a job well done, then she'll come in, and all you'll get is "well that's not very bright is it?"

Ahahahahahahahaha! CLASS! Dismissed!

So god damn true

[Oaktech]

tell her she needs to find the money for one of these:

 

Barco | Large venue projectors | 20,000 lumens, 1080p HD three-chip DLP projector | FLM HD20

 

that'll do the trick... and be retina burningly bright at the same time.!

[mrbios]

Holy crap and probably burn a giant hole in the school wallet at the same time

 

Looks pretty epic though.

[Oaktech]

about £70k.... plus an appropriate lens at about £8k-£12

 

eep!

Mother of God that's a whole year's budget.

 

 

...does it do 3D?

[CyberNerd]

how about an interactive LCD display screen? could be an option

[jamesreedersmith]

No you need two for that!

[Oaktech]

nope... for that you need a galaxy series, and about another £30k (but that does get you another 12k lumens, and about 200 hours less lamp life)

Someone explain this to me as i'm unsure if i've got this right:

 

Projector is 5 metres from the wall

Current screen size is 275cm diagonal

 

Does that mean i'd be able to adjust the image anywhere between 254 and 381cm diagonal due to the 5m being both the minimum and maximum distance for two different sizes in this table?

 

EDIT: That graph is for this projector: http://www.suppliesforschools.com/productinfo.aspx?tier1=AUDIO+VISUAL&tier2=Projectors&cmd=list&refine=true&manufacturer=Casio&catRef=OR708654 so if anyone who has used one of those comes in, please let me know what you think of it.....need to go and check out some other prices for it to so any thoughts on the pricing there would be appreciated.

According to this projector calculator, an XJ-M140 at 5m would have a screen size of 2.54m to 3.81m diagonally. Which is the same numbers as what you got, which would leave me to believe that yes, you should get an image to fit at 275cm.

 

Should.

[Oaktech]

^^ what he said...

 

*should* because these calculators assume there is no keystone involved, if you need to add any keystone then you will need to increase the throw distance as the image will be smaller!

Lovely jubbley

 

I've been looking for an excuse to try out these casio projectors for some time, nice to finally have one that we don't have to pay for ourselves

Oh they are good - our teachers love 'em, which is lucky, cos so do I

How much are the replacement bulbs for them (at 20,000 hours i'd be hoping to forget by the time i needed to change one ) as all the places i look say you have to ask for a quote, could do with a rough estimate though just so i have some idea?

Not a clue - think we put our first lot in about a year ago (the A range) so not expecting to think about that for at least half a dozen years yet. Although I always figured that when that happens, you replaced the whole projector, and by that time other companies will have caught up and we'll have some competition and economies of scale so hopefully they will be cheaper. Still cheaper over the lifespan than equivalent bulbed projector.
