Check this out ya'll.... They're expensive....but what I've heard first hand is that they are going to blow away everything we know about reef lighting. The following is a collection of posts by various authors from RAG.... Here's the pic: A LED hood!!!!!!!!!!! Some specs: Includes Solaris LED Hood, 8â€™ Detachable Cord to Remote 120V Power Supply, and Moon Lights. The system will be set for approximately 20K color. Without the Control Module the color will not be adjustable. The control module needs to be installed at the factory at time of order. (Note: PFO reserves the right to make changes without prior notification.) Warranty: The system is warranted for two years to the original purchaser. However, the white LEDâ€™s are expected to last 50,000 hours and the blue LEDâ€™s are expected to last 100,000 hours. Installation Precautions: The LEDâ€™s will have premature failure if they get too hot for an extended period of time. Ensure that there is good air circulation around hood. It is best to mount the LEDâ€™s over the tank via the stands or PFO Pendant Hanger Kit(Not Included). Be extremely careful about air circulation mounting inside canopies. If installing in canopies be aware the cables come out the end and add length for cable bending beyond stated length.

However, PFO Lighting reserves the right to change the date due to unforeseen circumstances. Control Module The blue LEDâ€™s, white LEDâ€™s, and Moon Light LEDâ€™s are controlled independently and will be dimmed using Pulse Width Modulation. The control module has a built in timer and microprocessor which controls each group of LEDâ€™s independently. With the control module you can dial in the exact color of light ranging from 6.5K to 20K by adjusting the Blue LEDâ€™s Light output. To set the following variables you will go to PFO Website enter the values on the LED Control Board Page. The new values will be downloaded to your computer and then you will transfer the file from your computer to the Solaris LED Light fixture via a USB cable. The current time will be set by your computer clock. When the Solaris LED Light Fixture has been reset, all lights will momentarily turn on and then it will look at what time it is and set all LED values to the specified values. I.e.. if it is half way through sunrise then all values would be set at 50% of maximum Daylight Options. The microprocessor will update LED light output values constantly.(Note: PFO reserves the right to make changes without prior notification.)

From a demonstration performed live at IMAC: Compared to a 20k XM 250 watt bulb. The hoods were at the exact same distance from the water's surface. PAR for the XM was 127.... PAR for the LEDS was 352 +/- 20 depending on how steady you held your hand. My next tank is sooooo gonna have this!!! If you could plug a fan and a water pump into it, you could even simulate storms!!!
