    can any one offer there opinion on projector brightness for a small pub installation i was thinking about a 2000 lumen dlp benq projector as they offer warranties that cover smokey environments such as pubs,

    do you think this is bright enough or should i go up to the 2500 lumen

    thanx

    Seeing that Pubs are not the brightest of places anyway you are probabley ok with 2000 but make sure that you look into a the contrast side as ( the higher the better) this will create more variations of the shades you PJ can produce also have a word with the guys in the screen room as they will be able to suggest the best screen (this is gonna be very important in the pub)

    Good luck, Darko

    You wont get many complaints if the image is too bright :)

    What size of image are you hoping to achieve, what screen material (if any) and how much ambient light is in the pub?

    There are a fair few 'smoke resistant' projectors on the market - that's not the same as a warranty that covers Smokey atmospheres; they simply have better filtration in the projectors.

    You still have to ensure you build in a decent cleaning and filter change regime - and hopefully not put the projector in the air stream of the pubs smoke extractor :)

    Best regards

    Joe

    Make sure no light falls directly on the screen, as it will wash out the picture considerably. A grey screen will help more with ambient light, especialy if it has some gain to it (Da-Lite do a 1.1 gain grey screen - the High Contrast Cinema Vision).

    Depending on the amount of ambient, a true 2000:1 contrast ratio projector may in fact only be able to realise 80:1 due to the bright black level that ambient light creates - the darkest black the screen can make is whatever it can do with the projector off. If the screen looks dull white, then that's your best black level.

    Gary.
