水草情迷

請問有否師兄用過此管呢? 它不用裝火牛, 安裝方便, 而且我個缸20吋, T5HO 根本就沒有適合我個缸用的, 有人知道T4適合種草的嗎?

T4 = T5
每個廠都有唔同名

T4 is only common in China, the fitting is not same as T5, the diameter of the tube is slight different, T5 is an international standard, even you not plan to use T5HO, you still have a lot of T5 choice in the market, so I suggest you to buy T5 is better.

GWU兄是對的. T4和t5的分別不單只是粗幼不同. t5是技術成熟的照明產品, 有國際標準的, 對光度.色溫.光效等技術水平有一定的規範. 而t4只是國內個別廠家生產的產品, 暫時並未標準化.

所以, 如果你對光度.色溫.光效等有要求就要用t5, 如果無, 只要夠光就得你可以用t4.
