各式燈具的優缺點 - 水族

我簡單的講一下各種的優缺點好了, 但我沒有全用過,也請有用過的指正

鹵素燈 鹵素燈穿透性強,投射面積小,比較適合深水缸 或是局部造景

優: 最高穿透性(60cm以上) 所以可以離水較遠做成吊燈,較美觀,也可欣賞水
草水面 上水上葉跟開花的美麗景象,整理水族箱也方便。
與同規格的非鹵素燈相較,發光效率較高
模擬太陽的全光譜,所以可算是最適合水草的生長,演色性也佳,呈現出
水草自然的形象
缺點: 高品質的貴的要命,鹵素燈是點光源所以需要高品質的反射罩跟濾鏡將
光線均勻擴散才能避免形成像手電筒的光束,但是品質一樣關係著價錢
瓦數較高(一盞上百瓦),高耗電,關係到電費~哈還是錢。高熱,如果
用了兩三盞整間房間就會有夠熱,等於三個小太陽在你家,就算你受的
了,夏天的水溫降溫可能也頭痛,當然啦~有錢買冷卻機就沒在怕的~
還有他的全光譜也容易長藻,要小心管理

FL燈 燈管樣子就是我們常見的日光燈管,價格平實,多樣選擇,最常見

優: 他最大的優點就是燈管彈性大,有許多種各式各樣的水族燈管,一般燈
管可供選擇跟配合,例如可以配三白光一暖色光加強紅色水草照明。
不滿意隨時可以換光譜組合,價格也合理又好買。買到好燈管的光質
也很適合水草生長。是面光源,一般燈管會稍微比缸子長幾公分
所以比較沒有追光現象。
缺: 穿透力較低(約45cm)
體積大,強光缸幾乎就是完全蓋滿了整個缸子的水面,整理水草
需要搬離比較麻煩。燈管壽命較短,必須6~12個月就更換,否則光質即
大幅下降。
ps:目前還有一種t5燈管,算是一種新規格的日光燈(現在的日光燈其實就叫t8)
他的優點是燈管管徑較小一點,同瓦數發光效率在高一點,所以對於需要強
光的缸卻已塞滿整個水面fl燈的玩家而言是好消息,可以塞比較多支燈
管,不過他之前好像不是很普及,多用在商業用途,使用電壓也是220v
所以不是很好買(已經越來越好買),價格也不低。最近很多人流行把
fl燈具改裝成t5規格,還有光譜光質不明,不知道是否比t8有更好的表現
我想等價格普及,水族燈管上市,應該是會變成主流
PL燈 當初就是為了改變日光燈體積過大的不便所發明的燈具,其本質跟日光燈
其實是一樣的,pl燈其實就是pl型的日光燈管。
優: 省電,便宜 君不見很多水族館賣pl燈具都是附燈管的,fl就不會附
穿透力比fl高(約55cm),小缸或是造型奇怪的缸(過深)其實不錯
缺: 佔空間 會有一大塊安定器,所以燈管只能橫跨缸面2/3造成追光
很多人反應pl燈容易長藻,或是水草養不好,還有演色性差(太死板的白)
其實這也不完全是pl燈的原罪,畢竟大多人得到的pl燈管都是送的,或是
隨便買檯燈用的,其實本身的光質就有問題,基本上它的發光原理跟fl
一模一樣,所以應該不會有孰優孰劣,主要就是我們一般能得到的燈管
品質就是普普,當然也有出水族用,但較不常見

==============================================================================

大家要有一個觀念,取決水草養的好不好的因素不止只有光度(亮度瓦數)

光質是最重要的,水草生長最需要的就是波長中的紅藍光 因為大多的葉子有葉綠素

呈現綠色,所以只能接收紅藍光,綠光會被反射不能利用。例如鹵素燈全光譜所以紅藍光

當然有,植物燈紅藍光強,但是燈光變成紫色,所以演色性差,水草顏色會失真

所以為什麼燈管會有150~2000的價差 如何在最適合紅藍光下再配出最佳的演色性

如何調整出最佳的紅藍光譜(適合水草生長)再調整成最佳演色性(適合欣賞最自然色澤)

這是水族的燈管的學問,一般燈管才不管那麼多,所以普遍燈管都不會列出光質供我們參

考,只能靠我們自己來判斷了

我認為現階段最適合標準水草缸(深度45cm)的應該就是fl燈,未來可能是t5規格

目前最實惠的燈管算是nec 演色性最佳的我目前感覺是ada

我目前用azoo跟sera 光盯著看就可以分出動物園的的確很糟 閃爍不講 燈管兩端已經
變黑......
