This is one of the most important fact of an LED BULB, it is the actual light you will get out of a light bulb. It is measured in Lumens. The more Lumens the brighter the bulb is.
Note: its wrongful that the brightness have always been given by the Watt. For example bulb known as 60 Watts should be called 800 Lumens Bulb.
The light appearance correspond to the color temperature of the light bulb. The measurement unit is the Kelvin.
2700 – 3000 K : from yellowish to a soft white color. Suitable for houses and any comfort area.
3000 K: Cool light that creates a very friendly, inviting, non-threatening, neat, clean, and efficient feel.
3500-4000 K: It is brighter than the incandescent cool white. Cool temperature light bulbs are great for executive offices, public reception areas, supermarkets, classrooms, and showrooms.
5000k – 6500 K: Daylight is a bluish white light that resembles noon on a cloudless day.. Bright light bulbs like this are great for jewelry stores, hospitals, beauty salons, galleries, and museums.
Note: We are expanding and plan to provide all the ranges of light colors for all the purposes.
Indicates approximately how much it cost o operate a light bulb on an annual basis. This is based on the daily average consumption ( Usually 3 hours) and the cost of energy in the local utility.
For example and LED bulb could cost $ 1.2 to operate annually while equivalent incandescent bulb cost approximately 10$.
Energy used ( Watt)
This is how many watt ( Power) the light bulb uses, the higher the watt the more expensive it cost to operate.
Note: note that although labels differentiates bulbs by Watt this has nothing to see with the brightness
