水草情迷

Hi,

My T5HO tubes are too bright for my 18" tank (because there are lots of "green tai" on the glass). I checked that the transformer is marked T5HO but I wonder if I can use T5HE tubes in order to reduce the brightness).

Many thanks.

唔得. HE管同 HO管火數完全唔同的.
飛利浦有出可調節光度既火牛, 不過應該好少店舖有吧, 可能要訂貨才有.

如果你真係將 HE 管 放係 HO 牛上面用, 係符合左 "超流" 既原理, 如果支管係頂得住多一倍既功率, 係會光左而唔係暗左, 仲會壽命相對短左囉.

睇下以前既討論.

Thank you all for your advice. It seems I need to add a sheild to reduce the brightness.
