Those are double ended industrial MH, they have a color temp of 5000K and below and its not suitable for aquarium use

so its not suitable because its colour temp is too low?


ok...thnx for clearing my doubts...

Saw a German brand (blue cover for the bulb).... I think is around S$40 rated @ 70 Watt ... , is that good ?

Sorry to steal your thread a little chua_hs, I'm going to setup a 3ft tank (3x1.8x1.8 with 2ft sump) and still thinking to get MH or PL light ... will one 70W MH enought ? My current 3ft tank is around 28'c with air cool.. I'm not too sure how hot the MH gonna bring to my tank...

70watts MH is not supported by the aquarium bulb makers, you will have very limited range of bulbs to use.

so if I use 150W MH in a 3ft tank, will I need chiller ? Tank normal temp with 2 x FL is around 28'c (fan cool)

u definitely need 1.

yes, you will need a chiller or very powerful fans. The glass casing of a 150watts MH can evaporise water on contact, that is how hot the bulb operates.

Know of some cheap industrial bulb rated at 6500K. It barely blue enough for marine use (beware microalgae will thrive better here), and to most the look of it is very unappealling.
