What are Delivered Lumens
Delivered lumens are the actual amount of useful light that is emitted and reaches a specific area or scene. It takes into account factors such as reflection, refraction, and absorption that can cause some of the light to be lost or redirected within the lighting fixture. Unlike total lumens, which measure the total amount of light emitted from a light source in all directions, delivered lumens provide a more accurate representation of the light available for use in a given space. This measurement considers the losses and interactions that occur as light travels through the fixture, ensuring a more realistic assessment of the brightness that can be expected.

The calculation of delivered lumens involves subtracting the amount of lost light from the total lumens. The specific calculation can vary depending on the design and characteristics of the lighting fixture.
Understanding the concept of delivered lumens is crucial for lighting designers, engineers, and specifiers as it helps them determine the appropriate number and type of fixtures needed to achieve the desired illumination in a space. By considering the actual light output that reaches the intended area, they can make informed decisions and ensure optimal lighting conditions.

常見問題
流明會隨着燈泡數量增加而增加嗎
燈泡數量與流明的增加之間並無直接關係。這是因為流明是發射光線的單位,而燈泡數量指的是光源的數量。雖然瓦數較高的燈泡通常會發出較多流明,但值得注意的是,燈泡的效率亦會影響發出的流明量。因此,即使兩個 LED 燈泡的瓦數相同,根據其效率的不同,發出的流明量仍可能有所差異。
What Lumen Is Closest to Daylight
If you are looking to replace a 60 watt incandescent bulb with a daylight bulb, you will need an LED light bulb with a wattage of 7 to 10. These bulbs typically have a lumen range of 650 to 800. Daylight LED light bulbs usually have a color temperature between 5,000 and 6,500 Kelvins.
勒克斯(Lux)與流明(Lumens)哪個更好
每平方米一流明相當於一勒克斯。這種測量單位使我們能夠量化可見光的整體「數量」以及表面上的照明強度。由於勒克斯能夠有效確定光束的感知亮度,因此被廣泛使用。
How Many Lumens Is Good for a Kitchen
Kitchens typically necessitate a higher level of illumination compared to a living room or bedroom. The specific amount of light needed will vary based on the kitchen’s size and arrangement, but as a general guideline, it is recommended to have approximately 70-80 lumens (units of light) per square foot in a kitchen.
Do LED Lights Have More Lumens
The efficacy of tungsten incandescent bulbs was only about 15 lumens/watt, while LED technology typically produces 75-110 lumens/watt. Therefore, LEDs are generally around 7 times more efficient at producing light compared to incandescent bulbs.
