I did a review of theCurrent USA 460nm Actinic Powerbrite LEDs on SDReefs so I thought I would post it here as well. Sorry if it should be in a different forum, if so, mods please move 
Here's the link to the homepage http://www.current-usa.com/powerbrite.html
suggested retail: $69.99 for the powered system and $54.99 for the link module.
street price: I've seen them online in the range of $50 for the powered system and $40 for the link module.
I paid $110 for the 3 of mine
Pros: Great color (alone they act like blacklights, really glowing corals)
super small profile (can be used for many unique applications)
super low power consumption (4 watts per strip)
very little heat
up to 3 strips can be linked and powered by one plug
price/life ratio (I think even at retail price they're a good deal)
Cons: the light beam is a bit too directional. This might be an issue for those who cannot give sufficient vertical space between the strip and the water surface or for bigger tanks where large areas coverage is desired.
price (for the size, I think some will be put off by the price tag)
I have a unique situation. I want actinics. But in order to keep using my MH pendant I was going to have to build a custom canopy to house 3 PC actinic fixtures, which are bulky, produce heat (the ballasts anyway),would have run about 54 watts, and would have needed bulb replacements over time. After much research and going back and forth I instead purchased 3 of the 460nm Actinic Powerbrite LED strips to use as actinics on my 42g hex tank. This turned out to be a perfect solution for me needing no canopy, producing very little heat, using only 12 watts and lasting (supposedly) 10-15 years.
Personally, I love these lights. The mounting to my Hamilton bell pendant was pretty simple (one $20 trip to Lowe's, quick and easy install which I can document if there's interest). I can imagine so many different ways of mounting these in different applications and they can also be set on top of glass using some rubber feet provided in the package. They're mounted about 8 inches above the water surface so there's a decent light spread, but I wish they were a bit less directional (might be an issue if sitting on glass). I can live with it, I've actually been considering adding a second set As and actinic supplement they have made my tank look so much more like I want it to and stand alone they make things look pretty incredible. I've been unable to truly capture the colors (themselves and for comparison) but have some crappy pics (dirty glass and forgot to take off glass lid ) below attempting to show what these babies do. BTW in case it isn't obvious in both sets of comparison shots the first pic is only MH, the second is MH and Powerbrites, and the third is only Powerbrites .
All in all, I recommend these as a viable actinic solution, especially for unique situations where standard PC or T5 lamps would be difficult. I can't comment on using them as stand alone light sources for nanos, I'll have to let someone else give it a try and do a review of the 10k or 10k/460nm combos.
