The key feature is its“plug-and-play”replacement compatibility.It utilizes multiple LED chips arranged in a full surround array on a vertical metal frame,paired with an efficient driver,to achieve near-omnidirectional light output that matches the reflector of the original HID fixture.The driver is typically built-in and compatible with wide voltage input,accommodating fluctuations in old power lines.It features a good thermal structure(e.g.,aluminum PCB+central heat sink column)to ensure stable operation even within enclosed fixtures.The luminous flux and color temperature can be matched to the replaced HPS lamp(e.g.,150W,250W).
Wide power coverage,from 30W(replacing 100W HPS)to 200W(replacing 400W HPS).Efficacy can reach 130-150 lm/W.Common color temperatures are 5000K or 5700K cool white,with 3000K warm white also available.Color Rendering Index Ra>70 is significantly higher than HPS(Ra~20),greatly improving color rendering.Operating voltage is wide-range AC85-265V.Design life is typically 30,000 to 50,000 hours.
Primarily used for energy-saving retrofits in locations with traditional HPS or MH lamps where the fixture itself is in good condition,such as municipal roads,industrial park roads,and parking lots.The retrofit process is simple and quick:power off,unscrew the old bulb,and screw in the LED corn bulb.This immediately achieves 40%-60%energy savings and improves lighting quality(better CRI,more comfortable light color).Note:if the original fixture's reflector is severely degraded or the seal is failed,a complete luminaire replacement is recommended for optimal optical performance and lifespan.
