D120 LED fixture

See Im new to LEDs. I asked on that group buy and they asked me " Why I need those Neutral whites" What is reason to have Neutral Whites really? Thanks. Sorry for silly questions.. Maybe I ask that question on new thread...to get quicker answer..

 

If you have an Apex and VDM, or an older Aquacontroller and AquaSurf module you can control a standard D120. I'll be working on a write up this weekend.

 

Its the spectrum they produce. I can tell you when I researched to build my retrofit for my 28 nano, everything I read said to be at a 2-1 ratio blues to white (with around 1/4 of the blues being UV (really TV)), go with either Neutral or Cool white (7500k) (these spectrums are supposed to be "better" for coral growth vs. 10k) , then add in 1 green or cyan (I prefer cyan) and 1 deep red for every 20-30 total LEDs or so (the reds especially can be overpowering). This is what I used for my build, and is almost identical in ratio to what Reef Breeders uses in their value fixture.

I know its not quite the help you were looking for, but just wanted to share what I found when I did my research trying to build full spectrum lighting.

 

Thank you for all your help. I really appreciate.

 

Im interested in this, also can i control dimming through this??? If so im very interested in doing this with my apex

 

Yes, that's the whole point...to control the dimming of the lights

 

I'm probably going to buy a photon 48, I have two of the ever grow fixtures that are basically the same as the reefbreeders photon 16, I would let them go for 250 a piece. Of you are interested

 

Hi - 1st post to this site! I'm on another board, WAMAS, and going participate in their next group buy for a D120. You say the LEDs can be swapped out. How easy is it to swap out lights?
