Epson goes lamp free with L-Series
Epson’s latest foray into 3LCD lamp-free laser phosphor technology comes in the form of the EB-L25000U projector. Thanks to its laser light source, the unit is reportedly capable of achieving an impressive 2,500,000:1 contrast ratio, while offering an overall output of 25,000 lumens of both colour and white brightness.
The laser source offers some other convincing arguments to houses of worship beyond just picture quality, such as the ability to mount units in any orientation, thereby allowing for both portrait and landscape aspect projections. Lamp life and unit reliability are also significantly increased with a stated maintenance-free use time of 20,000 hours quoted by the manufacturer. This is reportedly aided by the use of inorganic material in the projector’s LCD panels and phosphor wheel, as well as a sealed optical engine eliminating dust and smoke infiltration.
Furthermore, the unit reportedly adopts a lightweight design for easier installation, while at the same time offers a more durable casing. Other notable features include: adjustable brightness, status monitoring of signal, voltage and network information, power supply log, auto colour adjustment, curved surface and corner wall capabilities, lens position memory, and a wider lens shift range due to an improved stepping motor.
The shift toward to laser production also aids the unit’s green credentials. Traditional lamps, somewhat illogically, output white light before splitting it into its constituent red, green and blue elements. Ultimately this is recombined into a full spectrum picture for use on screen. As you can imagine, it’s not the most efficient process. Simplifying the technicalities somewhat, laser sources essentially separately create the three colours required in the first place, using less power in the process.
The 25,000 lumens L-Series flagship is joined by six models ranging in brightness from 6,000 to 12,000 lumens and outputting at WUXGA resolution with 4K enhancement. All seven models are compatible with nine optional interchangeable lenses which can be selected to best suit the environment, including the world’s first zero-offset lens which is reportedly capable of projecting a 100-inch image from 43cm away.
Joining the laser models is a high-brightness traditional lamp projector series designed for large venues. The EB-G7000 series outputs 4K images at up to 8,000 lumens and also features motorised lenses, allowing for adjustments to edge blending and curved screens. The device is stated to be operable 24/7 without requiring rest periods, thanks to a combination Epson’s Crystal Clear Fine Technology, LCD panels and cooling system.
The same nine interchangeable lenses compatible with the L Series can be used with the EB-G7000. Models in the range include an ultra-short throw, two short throw, one wide throw, four middle throw and one long throw configurations.
A collaboration feature offers split screen functionality, meaning two different sources can be projected simultaneously. The range also boasts 360-degree installation flexibility as well as connectivity for a range of inputs, including HDBaseT, SDI, HDMI, DVI-D, VGA and 5-BNC. The system is supportive of Crestron, AMX, Extron, Control4 protocols, with selected models also supporting Art-Net DMX for lighting control. Emulation of other projector brand control codes is available, eliminating the need to reprogram existing controller systems.
