LED lighting that improves luminous efficiency and contributes to energy saving in lighting fixtures.

LED lighting with an improved luminous efficiency of up to 7-8%! It contributes to energy savings in lighting fixtures and offers a comprehensive lineup that makes it easy to replace conventional products!

We have consolidated our core technology to achieve a maximum luminous efficiency of 142 lm/W (3000K/Ra90, Tj85, under rated drive conditions). This allows for brighter illumination with less power, contributing to energy savings in lighting fixtures. Additionally, we have improved long-term reliability and gas resistance characteristics. The energy-saving effects from enhanced luminous efficiency, along with longer intervals between replacements and repairs of LED light sources and lighting fixtures, also contribute to reducing environmental impact. By improving the amount of light obtained per package, we also contribute to the miniaturization of lighting fixtures and cost reduction. <Applications> Street lights, tunnel lights, floodlights, downlights, stadium lighting, etc. 【Features】 - Luminous efficiency: up to 142 lm/W (3000K/Ra90, Tj85, under rated drive conditions) - Supports a lineup of color temperatures and color rendering - Easy replacement from conventional products, covering 3W to 480W with 14 varieties across 4 packages (at Tj85°C) and reducing color variation - Improvement in maximum rated drive current For product details, please check our website.
