I don't have a tank setup at the moment, so any volunteers willing to help with reviewing the product?

Help with review? Does that mean buy the ones you just posted for sale?

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.

i have tried most of the led bulbs out there and the one you have shown will probably fail within a month-you would need a min of 3 watt led -the multiple mini leds do not have enough par(about 2 at 1 inch)

Since this lamp was manufactured based on our specs, it does come with 2 year warranty.

I quit the commercial operations in 2004, I am just trying my hard to have some alternate lighting options for the hobby that don't cost an arm and a leg.

How is a reflector going to have any effect on these? A reflector will wrap the sides and top of this unit. Are you suggesting to mount the leds pointing up?

Do you have par readings to back your claim at 6"? Pictures showing coverage of your 2'x1' box?

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.
