The bulb was $60, free shipping, the remote feature is awesome.... although no directions ;)  I'm going to buy another bulb to get better coverage of the tank..... I'll update pics of that when I get it!

Most SW equipment and stuff usually dosent come with directions lol...

 

Wat do u mean they measured par at 12" above the waterline? Was this graph on the site...

 

U want to measure par below the waterline! Where ur coral will be getting the light! Ur light will be 12" off the tank at least i would think....

 

Leds lose a lot of their par when they hit the water, i think its cause the water reflects it back but anyways...

My leds would meause in the 1000-1500par out of water. When measuring below, they would lose most of that! I cant remeber the numbers cuz it was awhile ago.
