What are Initial Lumens

Initial lumens are the total amount of light emitted by a lighting device immediately after it has stabilized, but before any depreciation in operational efficiency occurs. This measurement is typically taken after the first 100 hours of the lamp’s operation. During this initial period, the light-generating chemicals within the lamp may not have fully settled, resulting in fluctuations in the color of the emitted light, commonly known as flaring.

甚麼是初始流明

初始流明是指照明裝置在穩定工作後、且尚未發生任何運作效率衰減時所發出的總光通量。此數值通常是在燈具累積運作首 100 小時後測得。在該初始階段，燈具內部的發光化學物質可能尚未完全穩定，或會導致發出光源的顏色出現波動（通常稱為閃爍或偏色現象）。

製造商所提供的初始流明值，未必能準確反映此初始階段內的實際光輸出。事實上，燈具在運作初期所產生的光量，往往比標示的初始流明值高出約 20%。這種差異是由於發光化學物質在早期運作階段缺乏穩定性所致。透過參考初始流明，可以評估燈具在壽命初期所發出的光線亮度或強度。對於從事照明設計、安裝與維護的人員，以及希望對照明產品作出明智決策的消費者而言，此資訊尤為重要。
