Life and Light Output
LED Edison lamps have a longer lifespan than conventional filament, halogen and CFL lamps. Usually a LED lamp’s life span is 25000hours, it will last over 22 years (at 3 hours per day) against a filament lamp of less than a year and a CFL of just over 9 years.
How to Choose CCT for Your Bulbs?
Extra Warm White 2200K
The warm tones of this temperature give off a dim glow of light, similar to what you might find from candlelight; best for low-light areas where ambient illumination is welcomed. This is less commonly used but appropriate for the right setting.
Warm/Soft White 2700K
Kelvin produces a warm and inviting color of light. It is general the color of incandescent lighting. Choose a 2700 Kelvin bulb if the environment includes brown woods or warm colors like red, gold or orange.
Cool/Pure White 3000K
Kelvin is a cool and vibrant color of illumination. It’s preferred for work spaces, kitchen and bathrooms because of its closeness to morning light. Choose a 3000 Kelvin bulb for environments utilizing lots of cool colors like blue, green, or white. Grey Neutrals and stainless materials also go well with this range of light. For a cooler light, find a light closer to 4000K.
Kelvin is considered sunlight at high noon. It has a stark white or bluish appearance. This invigorating color should be used for security lighting, displaying artwork as well as commercial applications.
