I havent looked at the plasma yet but these look interesting indeed. I would need at least 4 of these so its a little pricey still for me - plus my fixture is only 6 mo old.. Theres no way to change the bulbs once you buy it? that would be a big drawback...
Looks like an interesting fixture. I'm hanging around the fringe market for LED, so I love seeing new things like this! What I do not love, however, are websites that embed music that is set to auto-play.
The thing with the LED lamp lifespans is that we REALLY don't know yet how long they will last in an aquarium environment.
IN a dry test environment we know they CAN last that long, but they just haven't beenaround long enough to REALLY know.
That being said.. I think LEDs will rule soon. MY DIY array is really... well... pretty awesome. I wish I had a way to measure the PAR vs my Aquactinics T5
