Product details:

The Straits Lighting Beam 360 LED Corn Lamp is an excellent replacement for metal halides, high-pressure sodium lamps, and CFL bulbs. Shatterproof construction and high efficiency LED chips ensures a long lifespan. These LED corn lights are approved for use in enclosed fixtures thanks to the patented heat dissipation system. If retrofitting HID fixtures, existing ballast must be bypassed. The SL915CBA is a 27 watt LED corn bulb that uses less energy than typical HID lamps. The product is easily retrofitted and serves as a direct replacement for 100W-HID bulbs.
