Radion Channel PAR Measurements

[FunkEngine]

Perhaps an odd request, but would someone with a Radion and a PAR meter be able to measure the relative PAR values for each individual channel when on the AB+ program? I don't have access to a spectrometer to tune my DIY lights, but I figure I should be able to get within the ballpark by approximating with the PAR values for individual color channels.

I would like to know as well!

I would love to test this. Maybe if I can convince ecotech to let me carry their product line. :D

You would have to match the spectral qualities of both lights closely for this data to be valid.

A simple lux meter would get just as close if you just want to set the light assuming you did your best to match the frequencies.

In fact someone with a lux meter and a Radion would likely be able to give you similar data.

I went with PAR as its numbers more people would be able to get for their lights or know about their light. I also understand that it would not allow you to exactly match the spectrum. That's not exactly the point here, its more so to give a ballpark reference for a "known good" spectrum when setting either DIY or other lights that do not offer spectral suggestions. In this case if everyone had a spectrometer it would be much more simple to set lights consistently well, but as far as I know almost no one has spectrometers or even access to them. By contrast while most do not own a PAR meter, many more will have access to one through local clubs. Its not an ideal solution, but I think it would be usable to get one close-ish to a good spectrum.

When putting together diy lights , many sites offer guides to assist one one in selecting leds to cover the desired spectrum and native color temperate. There are a few calulators that will help determine 'this too. (One here might help https://www.reef2reef.com/threads/great-led-color-spectrum-calculator.230899/#post-2686855)

If you're interested there are actually several low cost spectrometers available as well as color tempratue meters. One for the phone here.

I belive there are a few other ones now available as well like these on a phone

Also a simple prisim can be used.

Hmmm. #reefsquad any one with a Radion and a par/lux meter wanna experiment?
