While that may or may not be true, the Apollo's have custom casings, are shipped inside the US and have a warranty.
There are no prices on that link you gave and I can't find the same spec lights on their ali express page so how can we compare prices/warranties?
They're the same, but actually now that I checked they've dropped the price on the Apollos so much that they're a better deal:
Apollos:

Houyis:
http://www.aliexpress.com/store/pro...indoor-led-helios-grow/134227_1243829034.html
230 + tax on Amazon (at least tax for me and in most states nowadays), vs 288 on AliExpress. You could probably get Houyi to price match if you email them. They're nice people. I've got 4 of the 16x75w COB models and I've been pretty happy with them.
One thing to note though is you might want to have the 110 degree reflector to cover a 2 x 2 well with these things. The problem w/ LEDs is not penetration, it's coverage.
