Jerry's Everywhere LED Task Light

Lumen: Measurement of a quantity of light as perceived by the human eye. As a light source’s color temperature increases, less light is required to achieve comparable brightness and visual acuity. We do not have a lumen measurement for each brightness level for this lamp. Jerry's Everywhere LED Light: 24 LED Lights Color temperature: 5000°K Color Temperature: Refers to the apparent color of the light source. 2800K – 3200K considered “warm” ; 4100K-4900K considered “white” and 5000 K + “cool”. Comes from heating a blackbody (think of a piece of coal) up to a certain temperature; as the coal gets hotter and hotter, it changes from orange (i.e., 2300 K) to yellow (3000 K) to white (4700 K) to blue (5000 K) rendering. Color rendering index (CRI): 80+ Color Rendering Index (CRI): Measure of how well a light source replicates a given lighting condition; 100 being perfect, 90 good Energy consumption: 2.8W Lifespan: 100,000 Hours Dimensions (closed): 5.04" x 2.83" x 1.65” Includes a 43.3" long AC/USB power supply Accepts 4 optional AAA batteries (not included)
