The PRM 30 model from Promethean combines LCD technology in the Short Distance sector with 2500 ANSI lumens, a contrast of 500:1 and a native WXGA 1280 x 800 resolution. According to Promethean, the included lamp lasts up to 3000 hours. With its short projection distance, the short-throw model excels in smaller rooms, requiring only 106 cm of wall distance for an image width of 2 meters. Regarding projection size, the value of 2500 ANSI lumens allows for an image width of up to 508 cm in darkened environments. In rooms with ambient light, the image width should be correspondingly reduced to a maximum of 339 cm. For convenient remote monitoring and administration, the projector is equipped with a classic RJ45 network socket. Since entering the market in 2011, production has been discontinued; the manufacturer no longer actively offers the model. However, it remains one of the frequently accessed models in our database.
