AWESOME thanks for sharing!!

here are some readings of the Radion G4 Pro with diffusers...and yes there was water and wavemakers on for the readings

Thank you for these results. How far off the tank are your lights mounted? That's 75% intensity correct?

One thing i missed lol they are 12" above water and yep 75% intensity

Good info. I noticed some of my corals lost a lot of color after doing a carbon change. I thought my g4 with diffuser was dialed down enough, but evidently not. Slowly making a comeback.

I went back and looked at BRS Investigates videos for the Orphek, Sunpower and Radion XR30 G4. They are all within a percentage or two of each other if you keep in mind the height at which the fixtures are hung in the BRS videos. The Orpheks are hung at 12", the Sunpower at 8.5" and the Radions at 9". That puts the Orpheks at a good sized disadvantage yet the numbers were still very close.

The Radions put out slightly less par than the other two, but they are only 190W each while the Orphek is 235 and the Sunpower is 432. Given the power difference, the Radions seem to be slightly more efficient than the other two in generating par.

I've had all three units at one time or another (Orphek Atlantik V1) and they are all great lights. I've settled on the Radion XR30 G4s with T5 supplements and love the color I'm pulling and the quality of the light.

I'm not trying to steer the thread towards a Sunpower only to point out if you want the same performance/coverage you need two Orpheks- 740W and 3 Radions- 570w. I am talking about for dominant Acropora systems. You can get away with less for common mixed reefs.

Radions combined with T5 is fine if you want to go that route.

I'd have to go back and look at the video but I thought they were at the same height. My point was more about the coverage and consistency of the par distribution. I'll also point out you only need a range of 200-500 For a 24" deep tank. Most Led units can produce that now, but there is the bigger issue of coverage and spectrum distribution if you don't have enough units.

Everyone talks about Sanjay' tank.....he had a ton of units over his tank. More than double of what most people try to use.

The Orpheks are going to have a broader range simply because the LEDs cover nearly the entire body. Does that make sense? Orphek has always seemed to care that their LEDs are powerful and there's more of them. That doesn't mean the color blending is more beneficial for corals though. We actually decided not to test Orphek at all.

Yeah that's about right. Given they're that high up with diffusers the numbers are right where they should be. All lights were set where they should be...which means that the manufacturers even have certain guidelines of what they consider too close to the water that it might destroy the lights. All lights were cranked up as high as they would go at 13.5k.

Why did you decide to not test orphek at all?

I'm pleading the 5th on this question lol We won't be selling that brand.

:fish1: Hi, are you still planning on testing the Mitra LX 7206 light? :fish1:

 

[Reef2Land]

We're just waiting to get our new batch in, which should hopefully be soon. Some of them are coming from a bit further away.

 

[kjonulak]

It's been awhile any data on the GHL Mitras LX 7206 light?

 

[karliefish]

also keen to know if you have test the GHL Mitras?
