As far as actinics are concerned, blue leds are not actinics, a true actinic bulb is used in a photocopier and the like. Where is the specs listing 6" above the water? That's pretty vague for a height considering the range of depths for aquariums. Who is the manufacturer of these "reef specific" parking lot lamps? Where did you get them? These just look like a normal led replacement that someone desoldered a few whites and replaced with blues.

At 6" inches it will cast light in a 2' X 1' rectangle. but if you see the aluminum housing there are ways to focus this light to a smaller pattern using reflectors hanging of the periphery of the lamp.

The parking lot lamp was modified at my request to include the Cool White which has a full spectrum and also has the 420nm blue wavelength. To add 450nm I included the Edison 450nm Blue to the design.

All mods were made at the manufacturers production line. Also note that the layout of the blue LEDs, they form a 'W' which has been my nickname.
