High & Low Bay - LED Retrofit Lamps

LED High and Low Bay Retrofit Lights

LED high bay retrofit lights are great options when retrofitting metal halide (MH) or high-pressure sodium (HPS) bay light fixtures. These directional corn cobs differ from their traditional counterparts by having almost all their LED chips located along the bottom of the bulb. This makes these light bulbs ideal for retrofitting bay light fixtures where you want the majority of your light pointing downwards. Almost all the LED retrofits offered by us require that you bypass your magnetic and electronic ballasts! If you do not bypass your ballast, you will damage the bulb. LED corn cobs run off line voltages ranging from 120 to 277 volt. There are a few exceptions that work with the ballast, and these would be specific and obvious. Always refer to product listing details.

LED Lamp Bases

LED HID retrofit lights come in two different base types: medium and mogul. Medium base recognized by its code E26 denoting its Edison (E) base with a diameter of 26 millimeters. Mogul bases (E39) are roughly 50% larger at 39 millimeters. Typically, the higher wattage metal halides and sodium lamps (HID) come with mogul bases and smaller wattages have medium bases. However, some smaller bulbs can have mogul bases. Make sure when purchasing an LED corn cob to retrofit your fixture that the bases match or else they won't fit within the socket.

• E26 - Medium Base - Edison 26mm
• E39 - Mogul Base - Edison 39mm
• EX39 - Mogul Extended Base - Edison 39mm

Field Selectable / Tunable Lights

Most of the newer generation of LED lights have the adjustable power and color temperature settings so-called: field-selectable, field-adjustable, tunable...etc. This means that each bulb can have its brightness and light color adjustable before they are installed giving you enormous flexibility in your application's light design.

Color Temperatures

Color temperature (CCT) is defined by the Kelvin rating at which a black box radiation emits a specific color of light. Lower Kevin ratings have warmer (orangish) colors and higher temperatures have cooler (white / blueish) colors. Typically, LED corn cobs have two options to choose from:

• 3000K - Warm White / Soft White
• 4000K - Cool White / Neutral White
• 5000K - Day Light

Power Settings

LED HID retrofits are NOT dimmable lights. You cannot dim them with 120V line dimmers nor is there a way to dim them with the 0-10V dimming standard. To bypass this issue, new generation corn cobs have switches that adjust the power (wattage) setting of each individual light. This in essence gives you the ability to 'dim' the bulb.
