FAQs
What is a COB LED light, and how does it differ from other types of LED lights?
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.
How do I choose the right COB LED light for my specific lighting needs?
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.
How many lumens do I need for my COB LED light, based on my intended application?
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.
Can COB LED lights be used outdoors, or are they only suitable for indoor use?
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.
How do I install and mount my COB LED light properly?
Simply screw in to standard light fixtures with the E26 medium base. It is the same as a traditional A19 light bulb.
What is the expected lifespan of a COB LED light?
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.
What are the optimal operating temperatures for cob bulbs?
Cob bulbs are suitable for temperature ranges from -10ºF to 104ºF (-23ºC to 40ºC).
