Industry-Leading 91 lm/W Luminous Efficacy*1 in the 25W-Class Achieved

Sharp to Introduce High-Output, High-Color-Rendering*2 LED Lighting Devices


Press Releases

Sharp Corporation has developed and will introduce high-output, high-color-rendering 25W-class LED lighting devices that boast an industry’s highest luminous efficacy of 91 lm/W for light sources such as store spotlights.

As long-lasting, energy-efficient LED lighting rapidly becomes mainstream, the expectation towards light sources such as product-display spotlights in stores to be using high-output, high-color-rendering LED lighting devices is increasing.

These 25W-class devices*3 have achieved incredibly low energy consumption through the adoption of LED chips and phosphor, which both have excellent high-temperature properties. They provide a high 2370-lm luminous flux and the industry’s highest luminous efficacy of 91 lm/W. In addition, it achieved a high color rendering index (Ra)*4 of 83 by faithfully reproducing the colors of objects. Furthermore, the LED emitting area has been made circular to make designing lighting instruments easy.

Sharp will also introduce a 15W-class lineup to meet a wide range of customer needs.

Main Features

1. Industry-leading luminous efficacy of 91 lm/W achieved within the 25W-class
2.   Faithfully reproduces natural colors, with its high color rendering index (Ra) of 83
*1 The brightness per watt. As of February 9, 2011, for LED lighting devices with an input power of 25W, a color temperature of 3000K (GW5DMC30M04), and a color rendering index (Ra) 83 (based on Sharp survey).
*2 Color rendering describes how colors are perceived depending on differences in the illuminating light source. The closer to natural light, the higher the color rendering capability.
*3 GW5DMC30M04
*4 A numerical value expressing the level of color distortion compared to a reference light source.
The closer the value to 100, the lower the color distortion.
