Are LED tube lights as bright as fluorescent?

Yes, you may even be able to use fewer tubes in your fixtures. They use substantially less energy and have a life expectancy of ten years.

What does “cool white” and “warm white” mean, and what is CCT?

The Color Correlated Temperature (CCT) is given in the description of each of white LED bulb. The color (CCT) of white LED bulbs ranges from a warm yellow white (2700K) to a cool blue white (7000K).

How bright are LED light bulbs?

LED bulbs available for standard fixtures vary in brightness from less than 50 lumens up to about 1200 lumens. The brightest LED bulbs for standard fixtures are floodlights and spotlights.

How efficient are LED bulbs compared to incandescent bulbs?

The efficiency of the newer LED light bulbs is more than five times higher than comparable incandescent bulbs. In other words, LED light bulbs use only about 20% as much electricity to produce the same amount of light. However, because LED bulbs direct a larger percentage of light where it is needed, in many applications they are as much as ten times as effective as incandescent bulbs, reducing energy use by 90%.

How does the brightness of LED lighting compare to incandescent lighting?

LED light bulbs are much brighter than incandescent or halogen bulbs of the same wattage, but LED bulbs are not available in very high wattage. Thus, when replacing incandescent or halogen lamps with LED lamps, more LED lamps are often needed. For example, to replace one 100-watt incandescent bulb you may need two 5-watt or 6-watt LED bulbs. Although you have more bulbs you are still using 85% less electricity.

Which LED bulb is comparable to a standard 60-watt light bulb?

Few LED light bulbs with the same size and shape as a standard 60-watt incandescent bulb are comparable in light output. The closest LED bulb is A19 11W LED Bulb.

What is the difference between a floodlight and a spotlight?

LED spotlights output a narrower beam of light, typically less than 45 degrees wide. Most of the light from a spotlight is concentrated onto a relatively small area producing a bright spot. LED floodlights output a wider beam of light, up to 120 degrees, so the light from a floodlight is spread out over a much larger area.

Because the light is more concentrated, a spotlight will appear brighter than a floodlight but only within its narrower beam. A spotlight is more suited to illuminating objects and a floodlight is more suited to illuminating areas.
