黃金比: TERTIAL + Zailed 10W LED PAR20 5000k

對於一個1.3呎的小缸子來說燈具的選擇並不是這麼多，一般市面上的水族用燈具多設計給1.5呎或者2呎缸。曾經使用過一組中國製造的1.3呎 PL燈具，但一直有散熱不佳的困擾、尤其在夏日容易造成水溫的提高。最終這組廉價的燈具以短路燒壞燈管失收場。

There aren't many choices of light-fitting for a 1.3ft nano tank. What available on the the market are usually designed for 1.5ft or 2ft. I had a Made in China 1.3ft PL lighting-fitting, but have always struggled with the thermal solution, especially during the summer times when it created more heat to the tank water. This poorly made light fitting end up short circuit burnt.

開放缸對我來說有種莫名的吸引力，但又不可能為了小缸子特別去打造燈具。在因緣際會下在IKEA找到了這組桌燈TERTIAL，這組燈具能夠輕鬆的固定在桌沿而且採E27接頭，可以接各種E27燈泡、省電燈泡或LED。這組燈的銀色烤漆沉穩大方、且材質也很不錯，目前用了一年都沒有刮傷或掉漆的情況。能夠隨意調整角度也是它的優點之一。如此我的小缸也看起來像開放缸了.

I've always want to have an Open Tank, but could not afford a custom made high tech lights for the nano tank. I found this TERTIAL desk lamp from IKEA, which could be easily installed and takes all E27 socket incandescent bulbs, energy saving bulbs or LED. The cover finishes with silver paint nicely, there has not been a scratch since I purchased it a year ago; and it is multi-angle adjustable. So my nano tank somehow looks like an open tank after TERTIAL is installed.

燈具裡面我搭配了Zailed 10W LED PAR20。這顆PAR燈主要是用來做美術品照明、光譜並非針對植物所設計。裡面載有八顆CREE MX-6 5000k，紅色那段的波長的確弱了點。但散熱、演色、60度折射鏡和750lm...等原因都讓我選擇繼續用這顆而不換粉紫色的植物栽培燈。

I decided to use Zailed 10W LED PAR20. Although this lamp is design for gallery and museum environment than plant growth. It contains 8x CREE MX-6 5000k, which has less performance for Range of Wavelengths 600-700 nm (red). However, the advantage of its' thermal solution, performance, 60degree reflectors and 750lm makes me want to stick with LED lamp instead of the plant growth LEDs.
