    Really interested hearing about the communities experience with this light. I know it is a very new light but want to see if anyone knows about the par distribution or color.

    Also does this light have any shimmer or still the disco ball effect?

    Hope we can have a good discussion about this light and other LEDs alike

    FYI

    This is the Sponsor Forum for ReefLEDLights.COM

    I have not seen this light in person but here is my quick opinion/synopsis based on their website description.


    • 200W Variable Power Consumption with Waterproof Transformer
    UL/CE Listed?
    • Up to 500 PAR at 12"
    Pathetic Intensity!!! Not enough for SPS Clams or Carpet Anemones with a tank 24" or deeper. Snajay recommends a minimum of 100 PAR at the sand bed, we like 200-250 PAR.
    • Dual High-Density CREE LED Pucks
    What type of Cree LEDs... Bins????
    • 120° Quartz Wide-Angle Optics Provide up to 48" Spread
    We decided to go with a tighter optic to reduce spill and maximize efficiency. 48" spread on a 24"-30" wide tank = wasted light.
    • Unique Fill Light LED Strip for True-to-Nature Color Blending
    Fill LED Strip?
    • Dual Halo Moonlights for Wide, Even Moonlighting Effects
    Is the moonlight natural with a seasonal and nightly variation in intensity?
    • Full Featured 6 Channel Lighting Control with Ramp, Storm, Cloud, and Lunar Effects
    Good but our Sirius XTC has also a storm effect which we do not recommend using, as it can freak out some fish...
    • App & WiFi Controllable and Programmable with Nothing Extra to Buy
    Good
    • Shareable Custom Lighting Programs
    Good
    • Hanging Kit and Mounting Arm Options for Rimless or Rimmed Tanks*
    Excellent, we like the looks but at the cost of poor intensity...
    • Oversized Copper Heat Sinks for Maximum Heat Dissipation
    Not hard to cool a light that only provides 500 PAR at 12"
    • Dual Whisper Quiet Temperature Controlled Cooling Fans
    Great
    • Touch Sensitive Buttons for Quick, App Free Adjustments
    Good
    • 1 Year Warranty
    Only 1 Year :( !!!
    • Unlimited Cobalt Tank Tech Support Online or Over the Phone
    Good

    Hope this helps and please if you plan on purchasing a LED Fixture please check out our Sirius XTC. The Sirius XTC is 2600 PAR at 12" while consuming less than 160 watts. Our Powersupply is rated at 220 watts and is UL/CE Listed. All Major Components are UL/CE Listed and the fixture meets EU Class II Safety Standards as its only 24VDC. We also Manufacture these in the USA to ensure quality. Many LED Fixtures are manufactured in China and certainly cannot offer the best Cree LED Bins or even ensure the LEDs are not knockoffs or counterfeits of the highly efficient Cree X series...

    Feel free to contact us with any questions.

    "The Sirius XTC is 2600 PAR at 12"
    Anything over 600 par can kill some types of corals that like less light through too much light within days. A lot of corals do best in 150-250 par and the most demanding need no more than 500.

    From the manufacturer it looks like it when at 24 inch it has 700 par in the center it drops 100 par every 3 inches from center.
    The large blue peak we all want goes all the way over to 400nm the beginning of UV which can again actually damage corals. You typically want it lower by about 410-415nm to prevent this. 400nm is not bad but it's too close to full on UV to have it be one of the highest bands you are putting out. If all the #s on their site are right I could see this light burning corals up to 18-24 inches straight below it. And I can't imagine any coral that would survive long at a true 2600 par.

    Last on a line straight down from center it drops from 2600 par at 12 inches to 700 par at 24 inches down. That is a drop of 1900 par in just 12 inches further down in the tank. I've never heard of any light dropping over 150 par per inch! while going straight down. All the other high end lights drop less than 150 par every 6 inches.

    For the original poster the C-ray 200 looks like a great LED system. Similar to the Kessil AP700 and the Ecotech Radion XR30W G4 pro

    Corals are found at all depths were there is enough light. Most LED systems including those you mentioned are not powerful enough to produce 150-200 PAR on the sand bed of a 24-30" deep tank. To say that coral cannot do well with high PAR is simply wrong. We strive to offer light as close to natural as possible while being close to three times more efficient than a MH or T5Bulb

    Corals in shallow water develop pigments to reflect excess light. These pigments are often desirable as they enhance the color of some SPS. Below is a pic os SPS corals suriviving in the tropical sun with PAR Values well over 3000.

    Acclimation is key as to many corals from a LFS are often kept under weak lights. The Industry Standard for SPS is a 250-400 watt MH. I have yet to see a wholesaler or frag farmer use less.

    If your tank is 30" Deep and you want your Maxima Clam or Carpet Anemone happy and growing you need at least 200 PAR Dont forget that light intensity decreases by the square... Double the distance you have 1/4 the light. Our Sirius XTC is mounted 18" above the water and at 28" of water depth our Red Carpet Anemone receives 260 measured PAR... I feel that's perfect. Corals close to the top receive over 500 and have acclimated and are growing like weeds.
