Frequently Asked Questions

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. Our cob lights are not rated for enclosed fixtures, so post lamps and other similar styles are not compatible with these bulbs.

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.

Are COB LED lights dimmable, and what types of dimming controls are available?

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

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's the CRI?

These lights have a color rendering index of 80.

What are the optimal operating temperatures for cob bulbs?

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