LED Color Temperature and Kelvin Light Scale

LED bulbs have become quite popular over the previous years due to their brightness and energy conservation. However, LED lights generally come in various color temperatures whose suitability varies from room to room.

These color temperatures are typically measured using a Kelvin scale and labeled on the bulb’s box. However, though marked, you might end up buying an inappropriate color temperature if you are not aware of which color temperature is suitable for which setting.

Color temperature refers to the brightness you expect from a given bulb concerning its temperature measured in degrees Kelvin.

Unlike the typical manner in which you select bulbs using their wattage, where the higher the wattage, the brighter the bulb, in LED bulbs, color temperature is what you ought to consider.

LED bulbs with relatively lower color temperatures typically give off reddish-yellow hues, whereas those with higher color temperatures give off white-blue light.

Moreover, color temperature can at times referred to as the bulb’s Kelvin value.

2. What is Kelvin?

The selection of the best-LED color temperature varies depending on an individual’s requirements, as you will see in the article’s subsequent sections.

However, LED color temperatures typically fall into the below color temperature categories:

1. 2300K 

The 2300K color temperature is a low color temperature that produces warm white lighting. The warm lighting makes the color temperature ideal for areas where calm and relaxed atmospheres are required.

However, 2300K color temperature is not conducive for a variety of activities like:

  • shaving

The 3000k color temperature is the limit of the warm-colored lighting. similar to the earlier two creates a homely tone making it suitable for use in the bedroom and living room.

4. 4000K

The 4000K color temperature is high and results in daylight-like lighting that makes it suitable for lighting conservatories and garages.

The 4000K color temperature is also referred to as neutral or natural lighting by other brands.

5. 5000K

The 5000K color temperature is the limit of the daylight effect. Like the 4000K, the 5000K color temperature is conducive for use in the conservatories and garages, and dark office. The 5000K is usually also referred to as neutral or natural lighting.

6. 6000K

6000k is a high color temperature that gives off cool white light and tends to stimulate serotonin secretion.

Moreover, the bright lighting makes it suitable for use in areas that require bright lightings, such as in the bathrooms and kitchen.

How to choose LED color temperature for different rooms?

Just as the sun gives us energy, light bulbs to certain degrees also do the same. Installing bulbs that give off blue light waves produces serotonin making us alert, focused, and awake.

light ideas for basement

Basements and garages typically tend to be crowded areas with numerous equipment and boxes of things people no longer use.

As such, while considering appropriate lighting for these rooms, installing LED bulbs with color temperatures ranging from 4000K to 5000K is recommended as they will offer the best illumination enabling anyone going into the basement or garage to safely and operate with ease in there.

Moreover, having a handheld LED torch that emits a bright light will enable you to access sections where the lighting is insufficient. Unless you intend on installing overhead LED bulbs in hard-to-reach places also.

General office, Break Room, Conference, Lobby

In the office sections, the selected lighting should foster maximum productivity.

Therefore, installing bright lights with color temperatures of 5000K-6000K will stimulate the brain to secrete serotonin which will help keep individuals in the above areas alert and focused, bolstering their productivity.

However, ensure you position the LED bulbs such that unwanted glares do not form, especially when using computers.

Moreover, installing LED desk lamps might help improve the lighting and individual productivity because they allow the user to adjust the color temperatures to suit the reader’s personal preferences. Not one shoe fits all scenarios.

However, when it comes to the lobby and break room, you should opt for warmer colors such as those produced by LED bulbs of lower color temperatures. Warmer colors foster the secretion of melatonin that will help the guests in the lobby feel welcomed.

In the break room, to enable the employees to release the tension they accumulate during the work, install low color light temperatures. The lower color temperatures will help them perform optimally once their shift resumes.

Reading and Study room

As in the case with Offices, reading and study rooms ought to be equipped with LED lights that have color temperatures about 4000K.

The stated color temperatures stimulate the secretion of serotonin. Serotonin will enable the reader to remain focused and alert during the reading process.

Moreover, incorporating LED desk lamps will enable the reader to adjust the color temperature to his or her liking. The adjustment will allow the reader to maximize his or her productivity.

Soft white light vs. daylight
