Best led spectrum for fully controllable light?

[Flynsqwirl]

So I've had a reefbreeders aquasanrise led and can't find any info on it. I can control blues, royal blues, uv purple,red,green,and whites from 0-100% up to 18 time pointsa day but I think I have been using to much whites and want a good baseline for ratio of blues to whites and reds etc... if I could find a chart or somthing simular that would be great.

This might matter some which diodes are in it. If you post the actual kinds, you might get better answers. For example, some whites give off bad peaks and can harm corals in high numbers... but others not so much. Also, if the purple is really UV, or not, will help - you probably just have violet/purple and not UV (most LED manufacturers lie/fib and say that diodes at 405-410-420 are UV, but they are not - UV is below 400).

I would guess that you should baseline the blues and purple at the same, run green at 25% of this, white at 40% and red at 60%. Red is helpful to most corals. ...then adjust to taste. You will get better answers from other folks, but not too many people use the Aquasanrise as much as the Photon.

Here are the specs. Bought it for pretty good deal when it first came out . I was wondering why the photon was so popular and no info on this one. Was hoping it would end up being more popular. It's pretty powful at 50% and was bleaching out some acros. Been trying to hunt down a par meter to rent in so ca with no luck

The bleaching was probably from excessive peaks from the Cool White - this is not a too-much output thing, but a too-much bad spectrum thing. I think that you could probably turn the other channels up more without doing as much harm. Keep this channel low, IMO.

The same spectrum of 7500K from a T5 or MH could have many times as much output as that diode and the coral will thrive under them.

LUX meters are not expensive if you want to find one. They are a blunt instrument for this, kinda like driving a nail with a rock... but the nail will get driven. PAR meters themselves are still mostly a blunt instrument not counting a lot of the critical spectrum and also valuing excessive peaks, but this is more like driving a nail with a square piece of iron... better, but still not an empirical tool. You can roughly covert the LUX to PAR.

I pretty much went off the factory setting which is obviously wrong cause whites and blues were the same. I kind set it and left it cause couldn't find much info last year when I bought it. I was running the green and red about 15% max cause I thought red promoted algae. I like your analogies as well.lol
