The Westinghouse T30 LED Corn Cob Light Bulb is ideal for applications that require extremely bright light sources such as HID or high wattage CFL and incandescent light bulbs. As an energy-saving alternative to high wattage light bulbs, the T30 is the perfect replacement for barn/shop lighting, outdoor post top lanterns and wall pack lighting. Replaces high lumen 277-Volt lamps that operate on 277-Volt building mains voltage without a transformer or ballast. This durable LED maintains better light output than an HID bulb over its long 50,000 hour lifetime. Longer-lasting performance and dependability when compared to HID, CFL and Incandescent alternatives will minimize bulb changes and operational costs while reducing annual energy usage. In addition to producing similar brightness to HID, this LED offers superior quality of light, with a color rendering index (CRI) of 80. Suitable for use in damp locations and enclosed fixtures, this versatile medium base LED, with universal mounting position, can be installed in base up, base down or horizontal position. Includes LED chips on top to ensure omni directional light output, ideal for base-up applications. Westinghouse is a trusted, global brand. Westinghouse knows lighting and offers products with exceptional quality, reliability and functionality. Product reference number 35162.
