The LS751HD adopts the 2nd generation laser phosphor technology. In addition to inheriting excellent color performance, lamp-free design, and instant power on/off from the previous generation, technology on the new generation improves around 20% of brightness, better heat-resistance, and a smaller module design, making the images consistent in ambient settings as well as increased reliability with a more compact size for extended use in various scenarios.

Up to 30,000-hour Lifespan

High Brightness for Large Venues

Thanks to 5,000 ANSI Lumens brightness, you're guaranteed clear visuals of vibrancy with 1080p Full HD resolution which are perfectly suitable for large spaces with a lot of ambient light.
