RADIONS PAR CHART UPDATED...includes spectrums

[Eastamherstbias]

I picked up a generation 2 radion and put it on my main tank (4x2x2). I now have a Gen 2 on the left side and a PRO over the right. I am going to leave it that way so I can see if the UV/Yellow makes a difference with growth and color.

HERE IS MY COMPLETED PAR CHART WITH ALL VERSIONS OF RADIONS

GENERATION 2 PAR READINGS AT VARIOUS SPECTRUMS

RADION PRO READINGS AT VARIOUS SPECTRUMS

ALL DATA POINTS ON ONE CHART

As someone interested in trading up, thanks taking the time to get this info. Interesting numbers. Can you tell the difference with the extra spectrum looking at them side by side?

 

[Eastamherstbias]

The colors seem very similar between the gen 2 and pro. The pro has the UV so it brings out the fluorescence. The corals and fish pop a little more.

Eastamherstbias,

Thanks for providing all of us with the data on the Radion lights. The pictures (and graphs) speak volumes. Well done!

 

[Dmorty217]

Yeah wow! Thanks for taking the time to put this together for all of us. I noticed you didn't have the gen2 with the TIR lense I would assume the par reading would be similar to the gen1 jump to the gen1 with TIR lenses on them

 

[Eastamherstbias]

I had to check the ecotech site. The gen 2 come with the TIR lens automatically. There are no gen 2 without lens. The graph encompasses all current models of radions.

Good to know

Nice job with the par measurements and spectrums.:thumbsup: The lights are impressive.

 

[Geo_85]

Thanks for it. Been wondering if i can kinda raise the intensity going with 20k most of the time. Thanks

 

[Eastamherstbias]

I keep my tank on the 20k cycle. I tried to do a more powerful par plan and my corals were not a fan and after three months, I made an adjustment.

Thanks for the breakdown. I've been waiting for this...

Great work! Thanks again!!!!

Very informative- your aquarium looks great Austin!

 

[Eastamherstbias]

Thank you!

Could you test the lower kelvin as well? 7k mainly.

I'm curious since the 12k is higher in PAR than the 10k.

And thanks for doing this. I sold my par meter after I set up my DIY LEDs. The radions are going to be sweet when I get them put up in the next couple days.

 

[Eastamherstbias]

12k is all lights on 100%

 

[flamron]

Ok - I didn't know that.

But it still doesn't quite make sense in a kelvin rating sense, though. Typically, we always think a lower kelvin means more PAR - and this isn't the case.

The numbers look good but are your corals really blasted by that much light at the top of your rocks.
Leds are good and the ecotech programming is second to none but the spread on the light is its weakness
The Gen 2 seems to blow the Gen 1 with tir out of the water

That's because in this case, the "Kelvin rating" is simulated. Think of it more like "Looks like 10 000K" or "looks like 18,000K". The radion is built so that when all colour channels are running at 100%, the blend of all the diodes looks similar to the way a 12,000k metal halide bulb would to your eyes, so the only way to make it simulate the way a 10,000K or 7,000k bulb would look would be to turn down or turn off some of the blue diodes. Hence why on a radion, both lower and higher 'kelvin' settings put out less par than the fixture at "12K", because 12K is the fixture at 100%. Anything that looks cooler or warmer is achieved by subtracting from the fixture's total output.

The best comparison would be that if the Radion at 100% is equivalent to a 250W, 12K metal halide bulb, the same radion set at 10,000K would only be equivalent to a 200W bulb (I'm sure it's not an exact analogy but you get the point)

 

[asylumdown]

These numbers make me think that I could probably finance the upgrade to pros by selling two of my units. I have 8 over a 6'X3'X27", and even with the Gen 1s I can't turn my overall intensity up beyond 75% or everything bleaches beyond recognition. Even at 75% for only a few hours a day, I can't keep most LPS - open brains, scolies, and chalice corals bleach to death on the sand-bed in a couple of weeks.

 

[Bugger]

Well yeah when your using twice as many that are recomended
