The Lunera HID LED 360 5K is a LED mogul screw (E39) base metal halide or high pressure sodium (high intensity discharge HID) replacement with a 360 degree tubular lens orientation, ideal for post top lamps. Its opaque lens improves the optical performance, minimizes glare and enhances the appearance compared to other LED corn cobs. It is ballast driven, making it plug-and-play. At just 90W it saves significant energy compared to HID 250W equivalents. It is compatible with ballasts down to 150W. It has a high-bright lumen package of 8,600 lumens at 3500K, 4000K or 5000K CCT or 6,000 lumens at a warm 2000K CCT. It consistently outperforms hids over the long 50,000 hour life. It has a high CRI of 80 and it is warranted for 5 years.
