Basic Lighting Terms You Should Know

The world of lighting contains a wide range of information for both professionals and home users. Choosing the right light is an important factor that determines the atmosphere of the environment. However, terms such as “lumen”, “Kelvin” or “CRI” may confuse you. In this blog post, we aim to help you make more informed choices by explaining the basic lighting terms we hear frequently in our daily lives. If you wish, you can also take a look at Ronisu Lighting’s wide range of products for the most accurate lighting solutions.

Lumen (Luminous Flux)

Lumens measure the total amount of light emitted by a light source. In simple terms, the higher the lumen value, the brighter the illumination you will get. Nowadays, the “lumen” value is emphasized more than the “watt” value in light bulbs. Because while wattage only indicates the power consumption of the bulb, lumens directly give an idea of ​​the intensity of the light output.

For example, an LED bulb with a value of 800 lumens can provide brightness equivalent to a traditional 60-watt incandescent bulb. From this perspective, it is very important to consider the lumen value, especially in environments where you want to save energy. LED bulbs in Ronisu Lighting's product range provide optimum lighting by consuming less energy with their high lumen values.

Kelvin (Color Temperature)

The Kelvin (K) scale indicates the color temperature of a light source. Low values ​​(2700K-3000K) indicate warm or yellowish light, while high values ​​(5000K-6500K) indicate cool or white light. Warm light creates a softer atmosphere, while cool white light offers a brighter and clearer appearance.

In resting areas such as the living room or bedroom, you can create a warm and friendly environment by choosing a color temperature of 2700K - 3000K. In places where light and details are important, such as the kitchen, study room or office, a more neutral white light in the range of 4000K - 5000K can be preferred. Ronisu Lighting has a wide range of products suitable for the needs of different spaces and offers various options in terms of color temperature.

CRI (Color Rendering Index)

CRI (Color Rendering Index) is a measure of how accurately a light source reflects true colors. The value is expressed between 0 and 100, and as it approaches 100, the light source displays the colors of objects closer to sunlight. Lighting with a high CRI value allows objects to be seen without losing their true colors.

In areas where color accuracy is critical, such as kitchens, art studios or stores, lighting products with high CRI values ​​should be preferred. For example, light sources with a CRI value of over 80 are ideal for correctly perceiving the color of fruits and vegetables or seeing the true tone of a garment for sale. The products with high CRI values ​​that we offer as Ronisu Lighting offer both aesthetic and functional lighting solutions.

Watt (Power Consumption)

Watt (W) is a unit that shows how much energy a lighting device consumes. In old-style incandescent bulbs, brightness was usually compared in terms of wattage. However, with the development of LED technology, wattage has become a concept that only represents energy consumption. Higher wattage does not always mean more light.

You can reduce your electricity bills by turning to energy-saving products. LED bulbs can have different wattage options with the same lumen value. Therefore, it is important to pay attention not only to wattage but also to other factors such as lumen and CRI when choosing lighting. Ronisu Lighting offers modern lighting solutions that provide the best balance of wattage and lumen.

Lamp Life

The “lifespan” of a lamp or bulb refers to the length of time it will operate efficiently. LED technology in particular has a much longer lifespan than traditional bulbs. For example, a quality LED bulb can last between 15,000 and 50,000 hours. This reduces both maintenance costs and the need for frequent bulb replacement.

Factors affecting bulb life include voltage fluctuations, ambient temperature and usage. For example, lamps that are frequently turned on and off during the day may wear out more quickly due to the heating-cooling cycle. Ronisu Lighting provides both comfortable and sustainable solutions with its lighting products that offer a long service life.

Light Distribution and Angles

Light distribution refers to how wide or narrow a light bulb or fixture spreads light. The narrower the angle, the more intense, spot-like illumination is achieved. Wide angles provide general illumination, illuminating the entire space homogeneously.

Spot lighting can be preferred to highlight paintings or a specific area, while wide-angle LED panels or ceiling lamps are ideal for general lighting. Determining the right angle according to the purpose of use helps you both save energy and achieve the atmosphere you want. Ronisu Lighting's expert staff also guides you in choosing the most suitable light angle for your space.

Table of Basic Lighting Terms

Lighting is an important factor that makes our living spaces more comfortable and functional. When choosing a lamp, knowing terms such as lumen, Kelvin, CRI and wattage makes it easier for you to choose the right product. However, deciding what kind of atmosphere you want to create in your home or workplace also provides important clues about which lighting you should prefer.
