5200 Lumen LED Corn Cob Bulb ,40-Watt, 300-Watt Equivalent, 5000K Daylight, E26

COB stands for chip on board. A corn cob light contains many rows of small LED chips in an arrangement on a cylinder shaped bulb similar to corn on the cob. Hence the name “corn cob LED bulb”. Many of our other lights use the same quality LED chips.

Each space is different, depending on your ceiling height, number of light fixtures and location on the ceiling/spacing, the type of project you are trying to complete, and many more factors. As a very broad guide, you would want: between 2,500-5,000 lumen for a 1-car garage with 10ft ceilings, between 5,000-10,000 lumen for a 2-car garage with 10ft ceilings; above 10,000 lumens for a 3-car garage or any space with ceilings 12 ft and higher.

GT-Lite lights are damp rated. If used outdoors they must be protected from the weather: either installed under a porch/overhang, or in screen rooms and patios. Some COB lights are not rated for enclosed fixtures, so post lamps and other similar styles are not compatible with these bulbs. Check out our Lumen Tough line for enclosed and wet rated COB bulb options.

Simply screw in to standard light fixtures with the E26 medium base. It is the same as a traditional A19 light bulb.

Corn COB LED lights are non-dimmable. Use of dimmer switches with these bulbs will void the warranty.

Our cob bulbs boast a 25,000-hour LED lifespan, equal to 22.8 years when used 3 hours per day, 7 days per week.

Cob bulbs are suitable for temperature ranges from -10ºF to 104ºF (-23ºC to 40ºC).

When you see a light bulb or light fixture’s lifespan estimated, you will see that estimation typically measured in hours. This doesn’t mean that once you turn a light on, the clock is ticking, and once you hit that number of hours, the bulb is instantly shut off. The lifespan of a bulb is a rating that estimates its total operational hours. In an ideal environment, the bulb would meet or exceed the estimation, but people don’t live in perfectly controlled laboratory settings. What you can take away from these lifespan ratings is that it is just a rough estimation based on the type of LED used in each light. Customers looking to get the most out of their light should ensure that it is installed correctly, in an environment that best suits the light's design.
