Light Source & Luminous Efficiency
Light Source Configuration
Adopts high-stability 2835 SMD high-brightness LED chips as core luminous source, precisely surface-mounted on multi-facet aluminum PCB boards arranged in hexagonal column layout. The unique six-sided three-dimensional chip layout realizes authentic 360° full-angle uniform ring illumination, eliminating dead lighting zone, dark spot and uneven light distribution that commonly exists in traditional corn lamps. Each LED bead passes strict sorting screening for consistent color rendering (CRI＞80), low thermal resistance and minimal luminous decay; transparent anti-UV PC end cap protects internal chips from dust and moisture erosion while maximizing light transmittance without yellowing after long-term use.
Luminous Efficacy Performance
Boasts outstanding luminous efficacy hitting 120~145LM/W, drastically superior to conventional incandescent and HID corn bulbs. Rated lifespan reaches 50000 working hours with lumen maintenance rate over 91% after long-time continuous operation. Compared with traditional bulbs of equal brightness, our LED corn lamp delivers softer, flicker-free uniform lighting with no harsh glare, greatly improving visual comfort for indoor and semi-open ambient illumination.
Power Supply & Energy Consumption
Power Supply Design
Built-in high-efficiency isolated constant-current LED driver supports wide universal AC input range AC85~265V, perfectly compatible with mainstream household & industrial grid voltage across global markets. Integrated multi-protection circuit design including overvoltage, overcurrent, short-circuit and surge resistance safeguards the lamp against instantaneous voltage fluctuation and grid surge damage. Standard E27 screw-in base fits universal traditional lamp holders directly, requiring no extra wiring or fixture modification for direct retrofit replacement. The hollow vented plastic lamp holder forms natural convection airflow paired with full aluminum PCB heat sink to rapidly export working heat and stabilize driver operating temperature.
Energy Saving Advantage
Achieve up to 80%~85% electricity cost reduction versus old incandescent/HID lamps: a 20W LED corn light can fully substitute a 100W traditional incandescent corn bulb while outputting equivalent or higher lumen. Instant full brightness once powered on with zero warm-up idle power loss; high power factor ≥0.95 cuts invalid reactive power consumption to avoid extra utility penalties from low PF outdated lamps. Mercury-free, lead-free and no harmful ultraviolet radiation complies with RoHS eco-standard, satisfying global green lighting upgrade requirements.
Application Scenarios
Versatile for wide-range retrofit lighting occasions: indoor warehouse high bay pendant lighting, supermarket & retail shop ceiling lamp replacement, factory workshop auxiliary lighting, residential garage, basement, corridor and courtyard lamp, street garden post top lamp, barn & poultry breeding farm lighting, shopping mall atrium pendant light, parking lot canopy lamp, exhibition hall decorative lighting and all kinds of enclosed/semi-enclosed traditional lamp holder renovation projects; compatible with E27 based post lantern, wall lamp and high bay fixtures.
