I have the 4 bulb fixture on 24" deep tank. No problem with shadowing. Growth is as good as all T5. But color is better. And I like the shimmer effect. Just the perfect amount.
Never buy any ati 4 bulbs unless you have a really narrow tank. Even my 8 bulbs hybrid not cutting it on a 30"deep tank.
Nice growth. What is the par value at this SSC spot?
I have no doubt LED grows coral. I actually use leds on my DT currently. However, I'm upgrading to a 48" tank and want a nicer looking fixture fixture and want to give T5's a go. I'm just wondering if the led powermodule is worth twice the cost of a dimmable Sunpower and reefbrite comboI have great sps growth under the led part of my light in fact the most growth there, why would you advise against the led part?
Run the T5s at 100% during burn-in and at reduced photoperiod probably by 40% compared to original. Then once you burn-in bulbs increase photoperiod an hour weekly until back to original then start dimming. That's how I would do it.I'm adding 2 3' 8 bulb powermodules in the coming weeks. I'm switching from 3 6' Build My LED strips. I'm worried about acclimation/burn in. I'm a bit confused on the burn in aspect.
1.) You burn in the bulbs by running them at 100%, so how to you acclimate your tank to new lights if you have to run them at 100%? Move the fixture higher?
2.) Should I not use the LEDs for a bit while I burn in the t-5s?
Also,
3.) Which channel is which for the T-5s on an 8 bulb Fixture?
Thanks
I have already learned soo much from reading through this thread, but I've lost some answers to my questions along the way since I can't find the same posts again.
IMO the dimmable Sunpower and ReefBrites are the best color wise. The LED Powermodule is the best hybrid single unit, so aesthetically this is the best. If I had to redo I would go with the former since IMO the ReefBrites cannot be beaten for LED colors based on what I've seen at my LFS.I have no doubt LED grows coral.

Ok. How about which channel controls which T-5s on an 8 bulb model?
Channel #1 is the 2 outer bulbs on each side. (total of 4)
Channel #2 is the 4 inner bulbs.
