Lumens and Lighting Color Temperature

Lumens and Lighting Color Temperature 1Most people tend to believe that a bulb with more wattage produces more light. But the truth is that wattage is all about the amount of power a light to function. The brightness of a bulb is actually dependent on its lumen value (lm). It’s important to note that lumen isn’t just determined by how much power or wattage a bulb requires, but also by the technology it’s based on. LED bulbs, for instance, consume less wattage than filament bulbs but can emit an equal amount of lumen. However, this doesn’t mean that brighter light bulbs are always the perfect option- it only means they’re suitable for use in various applications.

Having a bright LED (light emitting diode) bulb in your kitchen can really be great, but would feel too bright for your bedroom. Going for a filament bulb instead would be an incredible idea.

Color Temperature

Lumens and Lighting Color Temperature 2Kelvin refers to the SI (International System of Units) measure of thermodynamic temperature, which is equivalent to the degree Celsius (°C). Kelvin, which is commonly expressed as K, is utilized in lighting design to measure a bulbs color temperature.

Different light bulbs vary significantly depending on their color temperatures. A bulb’s lighting color temperature is a measure of the warmth or coolness of the light it produces. Color temperature is typically measured in terms of the Kelvin scale. Up to 3500 K (an abbreviation for Kelvin) is often regarded as warm white colors, giving off a red-yellow appearance; great for living rooms, bedrooms, outdoor spaces, and dining rooms. Anything between 3500K and 4100K is described as neutral, giving off a yellow appearance and is best for kitchens, vanities, workspaces, as well as offices. 5000K is classified as cool, giving off a bluish appearance as the lighting color temperature is increased and is perfect for display areas plus work environments where intense brightness is required.

 Choosing Your Light Bulb

The amount of power a bulb utilizes is what’s referred to as wattage. Ideally, everyone wants to purchase a lighting fixture with the lowest possible wattage so as to save energy, but this will mean that they’ll have to compensate on certain things such as style, aesthetics, as well as CRI (Color Rendering Index).

The lumen value depends on the purpose for which the light is meant to serve. In the kitchen and dining room, for instance, you may want to install a brighter light bulb which implies a higher lumen value than that of lamps in the bedroom as well as side tables.

Lumens and Lighting Color Temperature 3All light bulbs have the same Kelvin color temperature. A 3500K incandescent comes with the same intensity of visual warmth/coolness as an LED (light emitting diode) or CFL light bulb featuring a temperature of 3500K. Color temperatures greater than 3500K are commonly suitable for commercial as well as hospital applications since the light is sufficiently bright. However, task lighting might be achieved at 4000 Kelvin and above. When choosing new lighting fixtures for your home, be keen that you factor in color temperature to ensure you are settling for the right thing.
