Another question regarding Radion. My current light takes up 2 spots on my EB8. I know the Radion only needs one outlet, but my question is does it even need a switched outlet or can it be dimmed all the way off without switching off the outlet? I I know the ReefRadiance can't be dimmed all the way off, will only go so low then actual outlet needs to be shut off.
Osiviper, this is a general rant so skip to bottom for my answer to the above question..
Ok, let me get back to the differences for a sec just to clarify where I'm coming from. Everyone has their own preference and everybody sees color differently. I can say this as a fact because it's the business I've been in for 40+ years. I know color. Professionally. I get paid to know it. And I must be good at it because I've worked for the same manufacturer for 30 years.
What matters is not how we see color. What matter is how the corals see color. What I explained earlier is my visual preference in color.
Control to get that color is another thing. Some lights have many LEDs mixing to achieve what that manufacturer tested for best growth, balanced with profitability and customer feedback. Some use better grade LEDs. Some use better drivers and control. Some use both. Some manufacturers use cheaper components to mix the output so it appears to be more balanced. There are many ways to achieve the output we need. Unfortuantly we are a niche hobby so none of them are cheap. Ok, there are some cheap units, but they will not provide anything more that light.
What's most important is what appeals to you visually, and what works for your system. I personally don't care who makes what and what feature they have. What I care about is how it looks to the coral, how it looks to my eyes, and how I can control it to achieve the first two points.
Everyone has their favorite brand. I can't state that ecotech is my favorite brand, but I use radion because it meets the criteria I set for my led. I can control the color to suit my taste and what best for my mix of coral.
Everyone has their own opinion and yes, there are plenty of fanboys of the manufacturers.
There is nothing wrong with tried and true here either, T5 is just that. If you don't mind a higher power bill and can deal with heat build up, they work well.
Bottom line when choosing components, buy the best you can afford, so you don't have to replace it six months down the line when your tank changes.
...I'll get off my soapbox now and ..
Back to your question. Radion doesn't need an outlet on the eb8. Unless you want a failsafe for high temperature. Neither would the reef radiance. They both use internal controllers to regulate their time and channels. Radion would use the wxm module to communicate to apex. Reef radiance would use the 0-10v port to accomplish its ramping through apex, or run on its self contained controller. Neither dim through the eb, just on and off.
