I've been thinking about my lighting situation more and more. I'm not happy with it. Here are the problems I have with it:
1) The build quality on the fixtures is suspect. The fans on one fixture completely failed and had to be replaced. I built a better fan subsystem for it. On the other fixture I have one failed fan... the rest will probably go soon. Mcliffy on our local forum had one of his ballasts go after just 10 months, and the "replacement" ballast shipped to him was a el cheap Chinese ballast.
2) The light spread is not what I had envisioned. The problem is that I have some heavy top bracing with 3 "cut outs". T5 fixtures hang over the left and right hole and the bracing between the left and right and the center hole. Very little light actually goes through the center..., its all light that filters through the bracing. The problem with this is teh bracing gets salt crud fast., I see a noticeable drop off when the crud builds up.
3) Maintenance. Its a total PITA. I have to keep the bracing clean, and weekly I have to wipe down 4 2 foot panels. I know it doesn't sound like alot but it takes time. That whole process is at least a 30 minute ordeal weekly. More if I keep the braces clean during the week.
4) Reliability. I'm afraid I'm going to have a ballast failure soon and I'm going to have to rebuild the thing dumping more money into it.
5) Ongoing cost. its going to cost me $500+ in about 3 months when it comes time to replace my bulbs.
6) No shimmer
7) Bulk hanging mechanism.
Now the positives:
1) Good par (I think, I'll know for sure when I get the par meter. but my eyes tell me its good par.
2) Great color. With the ability to mix and match bulbs I can get any color I like.
3) Staged on and off. I can bring banks on in stages simulating sunrise and sunset.
I'm thinking of buying a Lumenbright Large reflector, a good 400W ballast and a good 12-14k bulb. I'll make a much smaller mounting rig and give it a try over one of the holes to see what it actually looks like. Lumenbright III's at 30" over the tank give a nice 3x3 square which is what I need. Why?
1) The maintenance will be alot less. Its going to be easier to clean th much smaller reflector and bulb weekly, and I wont have to clean the bracing.
2) Reliability. Its a much simpler setup. Only parts that can fail are bulb and ballast and both are much easier replaced.
3) Cost. Changing 3 $70 bulbs every 6 months is much better than 24 $22 bulbs every 9 months
4) I'll have shimmer again.
Downside:
1) Colors will not be as good. I wont have Actinic supplementation. If I go this route I will NOT add supplement lights, unless I want to dork around with some LED's.
2) Heat. Although I don't think its going to be that big of an issue in my room.
3) I'll look like an idiot blowing as much money as I already have on the high end fixtures just to mothball them after 9 months of use.
Would like to hear your guys comments. I'm afraid this might be a bit of the grass is greener on the other side, but the maintenance is beginning to be a pita issue. Its not like I'm willing to spend time on the tank, but spending as much time as I am on the lighting is a pain.... I'd rather spend it in the tank.
