The temperature scale can help determine which bulb to use in each room. Kelvin: Color Temperatures of Light Bulbs Therefore, you should consider using a temperature color scale to identify the right hue for your application.īulbs with a color temperature below 3500K are ideal for household use, while those above 3500K are suitable for hospital and industrial use. The output of each specific kelvin temperature lamp Color Temperature ChartĬool temperature light sources (white/bluish lights) are very bright and can be harsh on home interiors. The unit measures a light bulb’s color temperature, and the higher the measurement, the whiter and bluish the light. What is Kelvin Temperature?ĭenoted by the absolute temperature unit (K), Kelvin is the thermodynamic temperature SI base unit equal in magnitude to ☌. On the other hand, watts define how much energy a bulb consumes. Therefore, lumens became a more accurate brightness measurement unit because they indicate the actual light output of the bulb. For instance, a 15-watt LED bulb and a 100-watt incandescent bulb churn out the same output (about 1600 lumens). Why? LED lamps are energy efficient and can produce more brightness for the same wattage as a traditional bulb. However, this yardstick measurement became irrelevant with the introduction of LED bulbs. With traditional bulbs, if you wanted a brighter one, you would get one with a higher wattage rating.
Kelvin: What is Lumen?Ī lumen is a unit of measurement that denotes a bulb’s brightness level.
LUMEN LIGHT SCALE PLUS
We have looked at these two light quantity and quality measurement units in detail below, plus how they stack up against watts and illuminance. There are two key factors to check when selecting bulbs (especially LEDs). When buying lighting fixtures for your home, workspace, or project, consider more than just the aesthetics.
