Need help! Which MH retro is better?
 

I just can't figure out which setup would be better quality. Let me know what you thing is better and why. This will be going over a 72 gallon bowfront with 2 t5 actinics.

or link to your personal preference.

Thanks

First and foremost go with mogul based. Second chose a reflector with large spread. Also it would be smart to get a dimmable/choose-a-watt ballast if you want to set up to 400W.

The Lumen Max is the better reflector. For ballasts I use Icecap but like the dimable ones made by Galaxy. I like HQI bulbs better JMO.

I would love to use a mogul base but can't find a reflector that fits over the odd footprint I have. I have 7 1/8" clerence in my hood.

CoralVue Lumen Bright Mini-Reflector are 16in x 16in x 7in deep

Sunlight Supply Lumen Max 2 Single Ended Mogul Base Reflector is only 15in x 11.5in x 5in.

Sunlight Supply Lumen Max Elite Mogul Fixture is 17.5" x 14.5" x 5.3". Lots of spread length wise.

As I said I only have 7 1/8" width.

Wow that limits you. All the other reflectors you had in the OP are pretty much the same, it will all come down to the ballast. Those reflector styles are not the best but they will work fine.
