hmm did you ask about shipping options.. I asked them about USPS ground and it was about 35 bucks for the shipping on a 10X28. never use UPS as there will ba a 35 buck extra charge from UPS to "clear customs"

I think it was USPS as well

sigh. i will keep my eyes open for a heatsink.

I was going to buy it anyways as I wasnted a one piece design, but ya there has to be something in Canada.

Above is the video of LED lited SPS tank. He's got 3 ballasts so looks like 3 LED strips.

here is the store that sells them.

Could it work for a Nano or a small cube tank ?

I would say no. It says it's 180 LEDs and 21 watts so regular 5mm LEDs probably putting out very little PAR. Also, lifespan of those types of LEDs is iffy as they are very difficult to cool effectively. The tank in the video looks like it has T8s or something as well in addition to the LEDs.

the life of the 5mm will be very good, and they don't need cooling to get that life. but like you said there is no par to speak of.. they are about the same PAR output as a NO T12 bulb from my testing about 7 years ago.

this light are good for FOWLR or FO tanks, not anything with coral.

Well, it all depends on how well ventilated the housing is on those units. 5mm LEDs will suffer from heat too. it's just that thermal management of high power LEDs is more critical because they put out alot more heat. But a tight, enclosed fixture with 180 5mm LEDs in it could potentially build up heat and reduce the life of the emitters. And you can't really use heatsinks and fans to cool the plastic type LEDs.
