Very Cool LED's!!!

I would say probably not as they say the modules are replaceable. To me that says each one is a single circular MCPCB holding the emitters and I think it would be very difficult and costly to have those made angled or contoured rather than flat.

I suspect they are just clustering as many LEDS together as possible to increase the output in the assumption that the lack of optics will provide enough spread. In the end it may well work for many people as most probably have their SPS in the back and center part of the tank anyhow and the front is usually free of corals or has lower light corals further down. So perhaps they figured it will work for a good proportion of tanks. But its not how I would want to do it. I have the same size array using nearly 40% fewer LEDS and electricity with a much more even spread of light.

I received a response to my inquiry about PAR.

>> Begin cut and paste

Please see attached PAR analysis at 29" for Black Python 160W. Also, we offer 30 day money back gurantee if results posted are off by 10%. We will be submitting our lamp to well known US aquarists for additional test to support our claim.

at 29" BP 160W without any focal lenses has over 200 PAR reading. I think it is obvious that it is supperior to any MH or T5 lighting.

The PAR anaylsis is here:



While costly, the Pacific Sun "Deimon" 3 x 160W fixture with 2 x 80W T5 looks pretty sweet.

This really isn't much more expensive than the Solaris PFO fixtures.

I did see this chart, possibly on their website. It is only at one distance. Is this in air or in water? Also, what are the PAR measurements at different distances or depths. Such as 6 inches down the tank and 12 inches down etc. I would want to see independent measurements first as I have seen all sorts of manufacturers claims on PAR etc. that were to good to be true.

As for cost, the costs of LEDs has come down dramatically since the Solaris fixtures were available so I think these are a bit overpriced now.
