Lumens and PAR

GulfCoastAquarian · 11-05-2003, 02:21 PM

I think I'm finding the same thing with my GE 9325K bulbs. Anything low down near the substrate like e. tenellus is starting to look a little ragged. Most bulbs will have an intense initial lumens rating and taper off to a lower level and maintain that for many years. Just need to add more bulbs.
I only connected two of the four outputs coming out of the WH5 ballast, so I'll just go and connect a third, and recover some of the lost initial lumens.

Well, now it's May, 2004. I just replaced the DULUX's from previous post for the same reason as before. This time I did use the GE 9325's. We'll see how they compare.

Take care...

I just got back into tanks after a 15 year leave of absence (lazy and poor) I have purchased a jebo fixture running 4 55 watt bulbs over a 90 gal tank. the setup is less than a month old. has anyone heard obout the jebo bulbs, currently I have 4 10,000k daylight bulbs in it. Should I run 2 Atinic bulbs and 2 10,000k? Oh and please consider me at least a little challanged, I have just enough knowledge to be dangerous.

Take a few minutes and read my Guide.

And no you don't want to run actinic bulbs over your planted tank.

Hey, lumpyfunk. Welcome to the world of planted tanks. It's addicting (you'll see

)

I found this article to be helpful is giving me an overview of aquarium lighting (click here for article).

I knew it would be dangerous. . .I allready have a lot of house plants and now a whole new realm of options is open. I got such a good deal on my light I had to go planted. . .
