4000 Kelvin Vs 5000 Kelvin

But task lighting may be useful at 4000K and above.

4000 kelvin vs 5000 kelvin. Color temperature is based upon the principle that a black body radiator emits light the color generated at the temperature of the radiator. If you are looking for brightness the proper measurement to look for is lumens. As seen on the graph 5000 kelvin is a nice white but has a slight tint of yellow.

A so-called black body which in theory swallows all light is first heated until it glows red. The lumens value describes the brightness of an LED light source or a luminaire. This is the specification that gives a description for the warmth or coolness of a light source.

A cool color temperature has a temperature of 4000-4500K. Double-ended power or single-ended power. Color temperatures of 5000K to 6500K approximate the color of a bright sunny day.

On the low end of the scale you have 1000-2000 Kelvin. These typically measure in at around 5000 Lumenssignificantly more than halogen bulbs. Read the full article on how to.

Right in-between 3000K and 4000K is 3500K which we often refer to. As seen on the graph 4300 kelvin is the color of most stock HID systems. Then moving up to around 5000-6000 scale you get to the white-hot zone.

The magnitude of a degree in Kelvin is the same as a degree in Celsius with 0 Kelvin equal to -27315 Celsius. Kelvin K is a unit of measure for temperature thermodynamic temperature to be exact name after the physicist William Thompson 1st Baron Kelvin. Daylight 5000 to 6500 Kelvin has a more bluish tone.
