I'm considering retrofitting a Current Extreme Nova 48inch T5 light fixture into an existing 48 inch hood on a 90 gallon tank. How noisy is the fan? How do you like the fixture? Any better or less expensive options?
I've had the 36" version for a couple of years now. The fan sounds like a jet engine. I've always meant to replace it with a better fan, but just haven't gotten around to it, so I don't run the fan at all. Couple that with the lack of individual reflectors, and I can say I should have spent a few more dollars for a better fixture. Well, I should be fair, and more specific. I can grow softies and some easier LPS with it. It just won't grow anything too demanding. Hope this helps.
I have two NEP 36" lights. The fans are(were) too noisy.
Since I have 12vdc in an umbilical line for the canopy fans (icepac and not noisy), I replaced the four fans in the two NEP with SilenX 80mm 9dBA 20 CFM fans(12vdc) and connected them to the umbilical line using quick connects.
With the four light fans and the four canopy fans operating they are less noise than one of the original NEP fans (rated at 20 CFM, 25dBA).
The fans do make some noise, I have the 48" fixture you are considering. It's not too loud though, and it seems to be plenty of light for everything I've put in the tank so far. I haven't even considered replacing the fans, but it wouldn't difficult or expensive.
I'm confident I'll have no problems with the clam and the SPS I'm planning to add. My tank isn't very deep though.
hmm, I'm surprised some people consider the fan noisy. I have the 48" NEP and I don't think their noisy at all. now, if EVERYTHING in the house is shut off I can hear them run if i'm near the tank. but what do you expect? they ARE a fan. I don't see how they can be 100% silent and still do their job.
