It is very likely that the manufacturer may not honor your products warranty, or that your product was never intended for the US market to begin with. If a competitor’s website has the same product but is not restricting the display/functionality in the same way that you see here on, than that competitor is likely NOT an authorized dealer. Some items may not be able to be advertised below a certain price or any pricing at all and others may not be able to be added to a shopping cart via an “add to cart” button. Why do I need to contact you in order to place my order?Īs an authorized dealer for the product you are looking at, is bound by certain agreements with our manufacturer partners in how we display, price and sell certain products. Outdoor Movies, Convention Hall, Lecture Hall Living Room, Classroom, Office Meeting Room For darker rooms like a home theater you'll need less, for brighter rooms like a conference room you'll need to have more. The number of foot-lamberts your projection set up needs depends on what you'll be using it for. So, in our original example where we netted only 13.9 ftL, if we introduce a 1.3 gain screen the formula changes as such:Ģ,000 (projector lumens) ÷ 144 (screen area) x 1.3 (screen gain) = 18.07 ftLĬongratulations! We have now taken this image from below the SMPTE standard of 16ftL to over 18ftL and provided a bright enough image for that particular screen size. (Projector Lumens ÷ Screen Area) x Screen Gain = ftL This would be represented in the formulas as: (What is Gain? – Read our Screen Gain Explained article.)Īll of the above formulas are making the assumption of throwing the projected image against a 1.0 gain screen surface. In this scenario you have more than ample luminance to deliver a bright image and a good viewing experience by reducing the size of the image you are trying to throw.ĭon’t want to go smaller with your screen? You don’t need to with a higher gain screen surface. If you were to reduce the image size to a 180” diagonal (13’ x 7.3’ = 95 square feet) than the math is as follows:Ģ,000 (projector lumens) ÷ 95 (screen area) = 21 ftL This falls just shy of the recommended luminance range, due to the size of the image. If you pair this screen with a 2,000 lumen 16:9 projector the math is as follows:Ģ,000 (projector lumens) ÷ 144 (screen area) = 13.9 ftL This screen with dimensions of 16’ x 9’ has a total surface area of 144 square feet. You have a 220” diagonal screen that is 16 feet wide and 9 feet tall – a 16:9 aspect ratio. The higher the ftL, the brighter the image will be for the audience. You may find that lower levels are acceptable to you you may also find that brighter values to be hard on your eyes in a room with controlled lighting.įortunately many projectors have settings to allow you to dial down the brightness should you find it to be too bright.Ī good layman’s rule of thumb is to have a total luminance of between 16-30 ftL in a dedicated theater space.Īnything lower than 16ftL in a completely dark room is not recommended. We recommend a total luminance of 40ftL for environments with moderate levels of ambient light and 60ftL for environments with high levels of ambient light. This is the standard for a professional cinematic viewing experience.įor environments with high levels of ambient light, maintaining good contrast is essential. The Society of Motion Picture and Television Engineers (SMPTE) recommends 16 foot-lamberts in a dark movie theater. Foot-lamberts (ftL) are the unit of measure used by the motion picture industry to specify how much light should be reflected off the movie screen in a 1-foot x 1-foot area.
