might blind someone =D
I need some help here, How would you arrange 5 LED's on a 12" strip.
RB, CW, RB, R, RB?
Royal Blue, Cool White, Royal Blue, Red, Royal Blue?
Is there a better way?
and 1 more question, can you use 1 driver for cree XP-C XP-G and XP-E LED's?

see I am no expert on LED"S yet....But the way i get it no. You must run separate drivers for each color/type. I am planning on 24 royal blue and 12 cool white. i hope that is enough white though....But i guess if i have to add another set it will be easy to add to..... And I believe depending on the driver there is a min. of lights like 8 that's how i understand it.

You don't have to run separate drivers for each color....You can run a mix of bulbs from the same driver, just most opt to put each color on a separate driver for the simple fact if they are dimming the can dim blues separate from whites and so on.......
1Snapple if you search out the LED threads on RC there is a build where a guy did a sketchup and everything as to how he was laying out his LEDs.......I don' remember exactly the title of the thread, but there is one covering how he was planning on laying them out.

I have been looking, I know you can put the cool white XP-G R5s and the XP-E royal blue's on the same driver, i am just not sure about the XP-C reds.
I get laying out the LED's it's just there is no way to make them even. I don't know how to make it so the white and red spread across the whole tank, Maybe no lenses?

Well right now i am trying to find a driver to run XP- E XP-G XP-C LED's. and no dimming but if the driver has that option i would buy it but it's not mandatory.

Do a search for MeanWell.....I know it's ELN-.... but not sure there is 2 different ones....1 is dimmable and the other isn't.....I did have a notebook with all the goodies written down, but can't find it of course....

Yes the MeanWells could drive all 3 LEDs, but what is the wattage of the reds your looking at? I don't know about mixing 1w LEDs with 3w LEDs on the same driver, since you can go in and tweak the drivers for how you want to drive the LEDs.....

The ones I was referring to were the ELN-60-48D & P models. I don't remember off the top of my head, but these are the common 2 used.....

I would honestly contact the makers of the MeanWell drivers and ask them if those are dimmable or adjustable where you can ramp the voltage up and down.

Never go cheap on the lights if you want coral. I upgraded 3Xs and it cost a fortune.
I run 2 X 175w MHs with 2 X 96w actinic…12K bulbs on my 90g. Nothing beats the looks of MH lights dancing in the water. Mine are on a pulley system, I also put some shades around the lights to block the light while we watch TV.. I can lower and raise the lights for maintenance or to control heat. Halides get hot.
With those lights I can have any corals I want. I made caves so I can have the corals that don’t care for lights as well.

Flower,
I like the Pulley Idea but id like to keep it all in the hood if possible. The whole hood would come off in one piece containing the lights. Aa I mentioned in the other post. I could built some T5 fixtures and still have them removable from the hood and all. Have you ever seen this done?

Yes, I did my first one like that. I hated it. Now keep in mind I'm older and female. The hood got so difficult to remove to do maintenance or anything it drove me LAZY, since I didn't want to mess with it. It had quick disconnect electric cables...Yes it disconnected from the ballast but the cables were so long and heavy, I had to get it all off the tank top and drag the lines behind me to the kitchen where I placed the lights on the table until I was ready to put it back on. I liked the look of my canopy. I'm not a do it yourself gal, so I couldn't alter my hood, just used what I had already with retrofit MH lights.
As you can see I kept my canopy, but removed the top lid and left it open, then I have the lights on pulleys, I also have shades I made to fit around the top because we watch TV and in a sitting position the lights bother my mother’s eyes.....man is it convenient. I raise the lights. Remove that wood front that weighs about 5 pounds and I can do anything I need to do.
Oh and by the way. The 2 X 175w with 2 X 96w actinic MH Coralife light system I have now, with a fan and glass shield cost $450.00 delivered. My retro lights cost almost $1000.00 by the time I was done..

I contacted rapidled.com and he said that i can run all 3 on any driver except for 1 and i wasn't planning on using the driver he stated (forgot the name) he said i would have to turn down the driver below 1A
