AquaConnect 14k inconsistencies?
 

I have 2 400w AC 14k bulbs, and lately one is looking 14k, the other is looking like a 10k bulb. Switched ballasts, no difference. 2 months old. Anyone notice this with these bulbs?

Yes I have, I have no idea as to why, kinda was thinking i got sold a used one.

check to see if the nipple on the tube inside is facing the same direction, perferably upward in the fixture. for some reason sometimes when they face downward the spectrum will be yellower.

To the best of my knowledge, that's a rumour. I believe Sanjay proved nipple orientation didn't matter. But, what the heck, I'll try that.

And welcome to the board!

As we get older.. it matters very much! North=good South=bad

Shelley, are you saying I need some sort of support for my bulbs?? :)

I agree with you, I have a bad AquaConnect bulb too, its also 14K. The colour is fine, but the growth I used to get under it before the crash was non-existent.

Well, my next round of bulbs will be back to Radiums I think...

see what happens when you go with 400's

Hmmmmmmmmmmmmm Brad you went to 400's i see. what was the reason. other then keeping the bulb up higher an allowing for a better spread..

Mike, the reason is J&L shipped me the wrong bulbs. I ordered 250s, but got 400s. I didn't even realize it until I went to fire them up, and then couldn't get replacements fast enough. I ended up having to buy new 400w ballasts instead.
I tried to go 250, really, I did!!

Why are you posting? You don't have a tank. Go away. If you're gonna harrass me, at least bring me coffee. At home! :)
