What is Lumen Maintenance
Lumen maintenance is the measurement of how well a lighting product retains its initial lumen output over time. It is a factor in evaluating the performance and longevity of light sources and luminaires. Lumen maintenance is typically expressed as a numerical value followed by the letter L or LM, which stands for lumen maintenance. This value represents the percentage of light output that remains after a certain number of hours of operation. Commonly used values include L50, L70, L80, and L90, or their LM equivalents.

For example, if a light source or luminaire is specified as L70 at 50,000 hours, it means that it will maintain 70% of its initial light output after 50,000 hours of use. This measurement provides an indication of how long the light source or luminaire will maintain a certain level of brightness before it starts to significantly degrade.
Lumen maintenance is an important consideration in lighting design and selection as it helps users understand how the brightness of a light source or luminaire will change over time. It allows for informed decisions about lighting needs and potential replacements. The nomenclature for lumen maintenance is evolving. The current practice of using L or LM values may not be sufficient for comparing products or determining their useful life. A new measure is emerging, which specifies lumen maintenance at a specific number of hours, such as 100,000 hours. This provides a more accurate representation of how well a light source or luminaire will maintain its brightness over a longer period.

よくある質問
目に優しい適切なルーメン数とは
3500ルーメン以下であれば、人間の目は快適な明るさとして知覚します。しかし、直射光や反射光の明るさが4000ルーメンを超えると、人の目はその光を受容するのが困難になり始めます。
ルーメン値は高ければ高いほど良いのか
屋外や周囲の光が強い部屋で機器を使用する場合は、高いルーメン値が不可欠です。これは、広々とした空間でプロジェクターを使用する場合や、より大きなスクリーンサイズが必要な場面にもあてはまります。
Is 1500 Lumens Too Much
If you are using candles as a light source, you will save a significant amount of money on electricity, but the amount of light emitted will be limited. For general lighting purposes, the U.S. Department of Energy recommends looking for light bulbs that have a brightness level ranging from 450 to 1,600 lumens.
