EditBrand
Each of the brands selected for the TELA Classroom Projectors scheme offer the capability to supply and maintain the projectors they sell and are first-tier vendors. Each of the projectors selected meet the scheme's performance and quality requirements. This allows schools to select their choice of models available through the scheme on the basis of the specifications and features they need.
EditDLP vs LCD?
DLP and LCD are two key technologies used for creating the images projected by data and video projectors. In classroom environments where there is ambient light we recommend LCD projectors be used. This is due to LCD's excellent colour brightness and saturation in typical classroom conditions. All current TELA Projectors use LCD technology.
EditWhat Specifications Should I Concentrate On?

Budget Contrained?
|
Lamp
|
Choose the longest lamp life available. A replacement lamp is generally cheapest when the projector model is new, therefore you can save on future lamp costs by ordering a spare lamp when you order a projector. |
Brightness - How Bright a Projector Do I Need for My Screen?
You need a bright projector to project a clear and legible image in bright rooms. The larger the screen you are projecting to, the brighter your projector needs to be too. Entry level TELA Classroom Projectors start at 2000-2500 lumens, depending on brand.
