水草情迷

i'm now using a lamp for a 20" set tank, if i want to change to 24" tank and can i just use the 20"燈 case and put T5 inside it ar? also is it gonna be bright enough?

please give me suggestion. thanks everyone!

夠唔夠光, 就看你是想用來種什麼草, 之後缸的高度是多少吧.
以20"燈殼黎講, 改裝成 36w PL 應該較好, 不過隻牛就要外置了.

好似短左D

thx for Super and 肥肥魚's answer

36w PL is brighter than T5?
i'll have most 陰性草...but wanna try some sun as well
the height is around 12-15" i'm not sure...

convert to PL is it easier than T5?

20"長既 T5管身, 只得 13W 一枝, 但仲未計兩邊腳位, 你個殼未必放得入. 當入到, 就要 3 支先接近 36W PL 的光度.
DIY 既難易度, 係看手工同埋工具吧, 不過如果你用 T5, 火牛就唔駛外置囉.

oh i see i see.....thx...hmm....then which one can save more power ar? also PL about how much?

or what if i buy a whole set of T5 to DIY, will it be cheaper then but 36W PL and 外置火牛?

大家都係用到接近既功率, 亦都係慳電管既一種黎.

三枝 T5(如果你用得著) 應該比 36W PL 平一點, 不過大家都係一百蚊以內.
找找"科聯" 問下價吧.
