General Lighting LEDs — Advanced LED Solutions for Industrial Applications

Application Overview

QUEENDOM’s General Lighting LED components provide the foundation for energy-efficient illumination across residential, commercial, and industrial environments. The portfolio spans the full range of form factors and performance tiers: from cost-effective 2835 SMD devices for basic bulb and tube replacements to high-performance 3030 and 7070 chips for premium downlights and architectural fixtures. Our general lighting LEDs prioritize efficacy (lm/W), color consistency (3-step and 5-step MacAdam ellipse binning), and long-term reliability (L70 >50,000 hours) — the three parameters that determine total cost of ownership for lighting OEMs andESCOs (Energy Service Companies). For commercial retrofit projects, our high-voltage LED series (48V, 120V DC) enable simplified driver designs that reduce BOM costs and improve system reliability by eliminating electrolytic capacitors. The flicker-free operation (<5% at all dimming levels) supports employee wellbeing in office environments while meeting IEEE 1789-2015 guidelines. For residential applications, our warm white (2700K-3000K) devices with high R9 (>50) render skin tones and wood finishes accurately, enhancing interior aesthetics. The comprehensive LM-80 test data and TM-21 lifetime projections support warranty programs up to 10 years.

Application Cases

Office Building LED Retrofit

A commercial real estate company retrofitted 15 office buildings (450,000 sq ft total) with fixtures using our 2835 SMD LEDs. The 130lm/W efficacy reduced lighting energy consumption by 58% compared to T8 fluorescent, saving $1.2M annually in electricity costs. The 3-step MacAdam binning ensured color consistency across 12,000 fixtures installed over 18 months. The flicker-free dimming (1-100%) integrated with daylight harvesting controls that further reduced consumption by 22%. The 10-year warranty and L70>60,000 hour projection eliminated relamping costs for the lease duration.

Residential LED Bulb Manufacturing

A lighting brand manufacturer produced 2 million A19 LED bulbs using our high-voltage 120V DC LED chips. The single-chip direct-line-voltage design eliminated the external driver, reducing BOM cost by 35% and bulb weight by 40%. The 2700K warm white with R9=58 rendered residential interiors with incandescent-like warmth while delivering 90lm/W efficacy. The compact chip size enabled omnidirectional light distribution without the dead-angle shadows of larger chip-on-board designs. The bulbs achieved Energy Star certification and 25,000-hour lifetime rating.
