Anti-glare COB Downlight UGR＜8

Premium Die-Cast COB Downlight with High Power Factor – 0.9 PF

The LD-03-404 series represents OKELI‘s premium die-cast COB downlight offering, engineered with a high power factor of 0.9 that significantly reduces reactive power loss and qualifies for energy efficiency incentives. Available in 7W, 10W, 12W, and 20W configurations across six models, this series delivers professional-grade illumination for commercial, hospitality, and residential applications where both performance and efficiency are paramount.

Superior High Power Factor Design

The LD-03-404 series stands out with its exceptional power factor of 0.9 – significantly higher than the industry average of 0.5-0.7 for comparable downlights. This high PF offers several important advantages:

• Reduced electricity costs: Minimizes reactive power loss, reducing overall energy consumption
• Qualification for incentives: Meets requirements for green building certifications and utility rebates
• Lower harmonic distortion: Reduces stress on electrical systems and improves power quality
• Enhanced system efficiency: Maximizes the useful power delivered to the lighting load

This high PF design makes the LD-03-404 series particularly suitable for large-scale commercial installations where energy efficiency and power quality are critical considerations.

Superior COB LED Performance

Each unit in the LD-03-404 series utilizes advanced SANAN COB (Chip-on-Board) technology, delivering 90 lumens per watt with RA80 color rendering. The COB design offers several advantages over traditional SMD arrays:

• Excellent color uniformity: No multi-shadow effects or color separation
• Superior thermal management: Efficient heat dissipation through the die-cast aluminum housing
• Higher luminous density: More light output from a smaller surface area
• Consistent color temperature: Minimal color shift over the product lifetime

Two Design Variants for Installation Flexibility

The LD-03-404 series offers two distinct design variants to accommodate different installation requirements:

Variant 1 (LD-03-40401, LD-03-40402, LD-03-40403):

• LD-03-40401: 7W, Ø64×H72mm, Ø55mm cutout – Compact design for small spaces
• LD-03-40402: 12W, Ø85×H88mm, Ø75mm cutout – Mid-range output for standard applications
• LD-03-40403: 20W, Ø101×H123mm, Ø95mm cutout – High output for larger spaces

Variant 2 (LD-03-40411, LD-03-40412, LD-03-40413):

• LD-03-40411: 10W, Ø60×H73mm, Ø55mm cutout – Compact high-efficiency design
• LD-03-40412: 12W, Ø81×H88mm, Ø75mm cutout – Standard output with optimized design
• LD-03-40413: 20W, Ø101×H123mm, Ø95mm cutout – Maximum output configuration

The availability of two design variants with overlapping wattages provides maximum flexibility for lighting designers and contractors【6†L7-L21】.

Elegant White Aluminum Housing

The white aluminum housing offers a clean, classic appearance that complements any interior design scheme. The die-cast construction provides excellent structural integrity and heat dissipation, ensuring long-term reliability and consistent performance. The IP20 rating makes these downlights suitable for indoor environments where moisture and dust are not significant concerns.

Versatile Color Temperature Options

Available in single-color configurations with 3000K, 4000K, or 6000K options to match specific application requirements. The RA80 color rendering index ensures accurate color perception for retail displays, hospitality environments, and residential living spaces.

Robust Electrical Design

Operating on 220-240V AC with a power factor of 0.9, the LD-03-404 series provides stable, efficient performance across standard grid voltages. The high PF design minimizes reactive power loss and reduces electricity costs.

Wide Application Range

The LD-03-404 series is ideal for:

• Commercial offices and corporate environments
• Retail stores and shopping centers
• Hotels, restaurants, and hospitality venues
• Residential living spaces and kitchens
• Educational facilities and institutional buildings
