I thought the Nova A4 was really good quality. I tried a d120 without optics and wasn't as impressed. The Nova heatsink is nice.
Next I'm trying the twilight group light with built in controller. Those supposedly have heatsinks, and you can ask for an aluminum housing. No one has gotten one yet to confirm the quality.
So is it going to be apex controllable by time you have completed it?
Thanks I was hoping you would chime in bhazard.
So with my tank being 21 inches deep would I go no optics? What if the light is going to be in a hood above the water a bit, 90degree optics?
Thanks again!
Here is what 2 d120's looked like on my 5ft tank. I think they have plenty of spread if they are not blocked by a brace

Now you guys have me worried about the lights I purchased. I went with two Twilight fixtures fitted with 60 degree optics for my 21 inch high tank. Should I try to contact Lyn and get this changed to 90? I was thinking of hanging these about 6 inches above the water if that makes a difference.
I know what lights you are talking about. I wouldn't suggest getting them. They won't confirm which bin of Crees they are using, so they might not be true Crees.
If you start going over $300+ per light for a chinese fixture, you're better off buying a commercial fixture in the US with a better warranty.
In your picture your lights are very high over the tank. If your tank is 24" tall it looks like the lights are almost 24" over the tank. If you lower than to 6" above the tank where many people put there lights to minimize loss is the tank still evenly lighted throughout?

If this is for your 75 gallon tank remember you tank is only 18" from front to back. So with the 60 degree lenses you still have a 29 inch spread with the lights 6" high at the substrate. At the surface you will have less coverage but the main idea is to light up the corals rather than the surface. If you end up with dark spots or shadowing to an excess you can move the light fixture further to the front of the tank and angle it to point at the bottom rear of the tank. This actualy creates an unbelievably nice shimmer effect as well.
I agree with you I think the ones in the $200 price rage are a great price.
But as soon as they start geting in the $300+ plus range i would spend more and go with the Maxspect Razor R420R It has the latest Crees with build in timers ect
