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.

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. |
