4x MH Reflector

[ntswift]

So I was reading the thread on DIY reflectors and was wondering if you guys saw any problems with just getting the sheet reflectors and just mounting 4 SE MH bulbs to the top of the hood? Kinda like [ I I I I ] with the ends built in. (like my drawing? ) Then mounting T5's for actinics on the top and bottom of that. I am looking at putting two 400's in the middle and two 250's on the outsides. by the way its a 265gal that I got from Jesse ( DBM REEF) Thanks!

You can do it but you are not going to get the same reflection as single reflectors.

What you're describing is basically a single "parabolic" reflector, over all 4 bulbs. This will work, but won't give you near as much reflectiveness as a "formed" reflector over each bulb. Even the cheap "spider" reflectors, that can be had for about $25.00 (new) each, are going to give you more light, into the tank. Also, are you talking about SE or DE bulbs? If DE, you'll need a glass UV shield, which may be difficult to incorporate, into your design.

Thanks! No, they are just SE...I will just have to go with the spider reflectors then. I have been finding them for about $50 each...Do you know where I can get them for cheaper?

I would also call Greg, at Reefgeek. Their site only lists DIY Retrofit, reflectors and ballast combos. However, I'm sure he also sells spider reflectors, individually, and will probably beat any other price you can find.
