一般來說 燈管的光衰程度
除了燈管本身 還要看燈具安定器的輸出功率
先來講燈管本身
以T5來講 光衰程度約在10%以下
T8燈管大於30%
如果在考量到安定器
第一個必需看安定器的PowerFactor(以下簡稱PF)
水族用燈具的安定器通常都是使用電子式安定器
PF都在0.9~0.95以上
而AD2及世界光的安定器都號稱PF在0.98
使用電子式安定器 因為輸出功率較高 所以光衰較快
但是因為輸出電壓穩定 所以會減少燈管氧化 增加燈管壽命
所以以T5燈管來說
不管光衰在快 到燈管不能用的時候 光衰都在10%以內
而T8燈管
光衰則是會大於30%的
在來
使用T8燈具的板友
如果想更換成T5燈 先別急
市面上有一種燈具叫做T85燈具
這種燈具很特別
是台灣研發專利
他使用的是T8的燈座 及T5的燈管
也就是在T8的燈座上 安裝上T5的轉接座 然後使用T5燈管
一般外面在販售 都是轉接座+燈管
買回家 直接安裝在家裡的T8燈座就OK了
所以 想換T5燈具的板友
可以去外面找找看 是否有你那組燈具適用的T85燈具可以安裝
T85燈具光衰也大約是小於10%
但是目前並沒有切確的數字 因為還要看本身T8燈具的安定器
