The BenQ LW61ST is the first in the world to be equipped with 'BlueCore', a light engine that utilizes the unparalleled qualities of a laser light source to achieve optimized energy efficiency, projection performance and readiness. It also incorporates the BlueCore-enhanced SmartEco™ Advanced technology to further reduce light source power consumption by up to 90% for a significantly lowered total cost of projector maintenance and ownership. Free of mercury, the BenQ LW61ST is a safer, smarter and environmentally friendly choice for your school.
80000:1 High Contrast Performance for Ultra Sharp Graphics and Text
Blurry images can be distracting for students to read and can cause eye strains and fatigue. The BlueCore light engine can dim the light source power up to 90% and still achieve a contrast ratio as high as 80000:1. This allows students to learn with ultra sharp images and text so they can focus their attention on learning.
20000 Hours of Optimal Brightness and Reliable Performances
The BlueCore light engine, powered by a laser light source in Eco Mode, has nearly three times the lamp life of a traditional mercury lamp. With up to 20000 hours of lamp life, the LW61ST offers a much more reliable performance with no sudden decrease in brightness.
Instant On/Off Projection Readiness for Classroom Instruction
It only takes a few seconds for the LW61ST to reach full brightness using BlueCore technology. In addition, it doesn’t require additional time to cool down. That leaves teachers with more time to teach without having to wait around between classes.
Users can adjust the brightness level of the LW61ST manually to fit the environmental lighting condition to save power. This is something you cannot do with a traditional projector. In the long-run, you're able to save power and prolong the lamp life.
360° Degree Tilt Projection
Thanks to the laser characteristics of the BlueCore light engine and the heat sink design, users have the flexibility to set up the LW61ST tilted 360° degrees in either direction around the vertical! This gives teachers the flexibility to place the projector any way they want and optimize limited space
Power Smart with the SmartEco Advanced Technology
Driven by BenQ’s latest BlueCore Light Engine, the all new SmartEco Advanced technology optimizes the core element of the projector – the projector light source system – to save up to 90% in light source power consumption! For schools that are looking for ways to lower the total cost of ownership, SmartEco Advanced certainly helps to reduce energy costs and extend the lamp life.
The SmartEco Mode automatically determines the optimal brightness depending on the input source. This special mode cleverly adjusts the light source power to maximize power saving – delivering the best contrast and brightness performance at the same time.
No Source Detected Mode
SmartEco Advanced activates the Eco Blank Mode after the projector has remained unconnected to a display source, such as a classroom PC or notebook, for three minutes, automatically lowering the projector brightness to 10%. This is to avoid keeping a projector from running with full lighting power, allowing the projector light source to rest whenever possible. Hence, the projector light source lasts longer.
Eco Blank Mode
The Eco Blank Mode allows teachers to blank the projection screen when the projector is not in use. Blanking the projection screen also allows teachers to direct their students’ focus back on them. Press the “Eco Blank Mode” button on the keypad or the “Blank” button on the remote control to activate this feature and watch the projector dims the lamp power automatically, lowering the total light source power consumption by up to 90%.
iPad/iPhone Display Connectivity
More and more schools are recognizing the benefits of teaching with Apple iPads – with teachers responding positively on how the devices have helped them succeed tremendously in engaging their students in class. The education applications open a gateway to a world of knowledge through a wide range of contents such as e-books, websites, newspapers, magazines, movies, music and games – offering students a more captivating learning experience in every subject. The LW61ST comes with iPad and/or iPhone wireless display support to expand onscreen content to over 80 inches and empower teachers to teach freely in class.
20W Speaker Power and Microphone Input Support
The LW61ST comes with enhanced audio support for your classroom. Two 10W speakers are sealed and secured within each side of the projector with BenQ's anti-shake design to deliver 20W crisp-clear audio performance with stable projection. The microphone input connects the projector to a conventional microphone or microphone headset for increased ease of teaching and learning.
