Hagen Glo or Nova Extreme T5's, which is better

[ElGuappo]

I have 2 GLO fixtures. a 48 and a 24. the ballasts are built in . if you are viewing one with a external ballast it is a retro fit. to clear up another thing there is no upgradable reflector. its a reflector for the retro kit. still the one include is pretty good. the deep horse shoe shape works well. and i would agree with 4 inches in width.

The hagen glo are cheap units. poor quality,
Found that a decent t5 unit puts out far more light than a hagen unit.
