水草情迷

想問下T5HO 可以照幾深ge缸？
我聽人講HQI可以比30寸深ge缸用，
而最old款T8個隻光管就可以比20寸深ge缸用，
唔知係唔係呢

仲有，T5HO同T5有咩唔同

T5HO should be fine for any tank of less than 24" of height. The dimension of T5HO and T5 is the same. The only difference is that T5HO is the "High Output" version which is more suitable for taller tanks. As read from some articles here, the 穿透力 of T8 is almost the same as T5.

我個缸有27寸高，
鋪左4寸泥，
即係水面至泥有24寸，
但如果支燈離水面6寸，
甘夠唔夠光？
仲有，T5HO熱唔熱架？
因為而家用緊HQI，
夏天太熱，
想換其他燈試下，
但又驚唔夠光

I'd say T5HO is not enough for your tank. BTW, HQI is the hottest device.
