Can you put a 36w t5ho tube in a 54w t5ho ballast?

My tank is 1140 mm long, as far as I know the 54w tubes are quite long, about the same size or longer. So should I get a 54w or 36w.....im pretty sure the 54w tubes wont fit in my tank hood.

Anyone know of watt vs length of tubes?

[land_lubber]

36w = 3ft t5ho

54w = 4ft t5ho

36w = 3ft t5ho

54w = 4ft t5ho

Thanks

Was looking at 54w tubes and using my "maori eye measure skills", but was too sure that they were too long.

Could be getting a 54w ballast will the 36w tubes be alright in it??

No.

you match 54W with 54W.

You cannot get 3ft 54W HO tubes - they are only ever 4ft.

Shouldn't you be working p44? :lol:

So if Im going to get a hagen glo ballast system (not a fixed hood length), I cant use a 36w in a 54w ballast (customised at 3ft length) in my DIY Hood/canopy? I know its wrong to assume but I thought that it might be "backward compatible".

I wanted to get the 54w ballast system so I can attach it to my hood like this

And I wanted it for future use, if I get a longer tank.
