6500k has 1ft power cord. If you have any issues whatsoever with this fixture eg. Expected light output, coral reactions, usability, ANYTHING have no worries. This LED technology in these custom color temperature Flood lights are beyond any other LED technologies available. Very efficient and loved by Reef Tanks everywhere!SHIMMER: If you are looking for the nice shimmer that Metal Halides give off this is one of the only type of LEDs you can use and still achieve that goal. Since the light output comes from a single point it gives a beautiful shimmer. With the 120 degree light output this light provides incredible light for any size tank. I would suggest using TWO of these 110-240 gallon tank. Could move up to 3 after for any 6ft tank... Gives off a great 6,500K color temperature. Incredible feedback from customers about Growth and Color of their Corals! Much less Heat, Evaporation, and Electricity! This is our oldest style below but same light output. We have just improved the housing design and efficiency. For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
