Just what I thought............damn.................the cree "option" better be the only option.
Let me support your thought ...
Afterall ,amongst other types of leds ,
I've a rather good experience of these 'cheap' 8 mm plastic case/lens leds ..
Of course there are 'quality ' options ,regarding this type of package ,like the ones from Seoul Semiconductors ..
But .....
Let us break down the % of the manufacturing cost of a LED device ....
http://apps1.eere.energy.gov/buildings/publications/pdfs/ssl/ssl_manuf-roadmap_sept2013.pdf
So you see ,that 60-65% of the cost of a led/COB/array is the actual package ....
Of course
ceramic ( AlO-BeO-AlN ) packages ,
copper slugs and
silicone lenses,is the high quality and cost option ...
( Cree -Osram -Nichia and other renown brands use those high quality materials ...
Only exception is the Bridgelux Vero series ,where the case is plastic ,but the chips are on
copper 'board' .Packaged by Toshiba .
Over the course of the next year(=2014), Bridgelux will be working with Toshiba to integrate its GaN-on-silicon LEDs into its Vero chip-on-board structure, Lester said.

The other option is the cheap
thermoplastic plastic case ,
aluminium slugs and
PMMA lenses (Plexiglass-PolyMethylMethAcrylate ),used in low quality ,cheap leds/arrays .
The latter option allows for
Volume Emitters to be packaged .
Volume emitters are cheaper and of older tech ,than
Thin-Film /surface emitters .
And of lower efficiency,also ...
Furthermore ,their thermal resistance is usually x10 or even x 20 greater than the
ceramic/copper packages..
Volume emitters and high thermal resistance ,is a great combo ,
to make cheap but shitty LEDS/Arrays ...
Thus ...
Yes ,If that guy behind the Amare Tech ,wants to be taken 'seriously ' ...
Better the Cree option ,to be the only option ,indeed...
Otherwise ...
Nothing different than all the rest ,of the Ali-Baba led grow lights ....
Meaning :
Same shit ,but ALWAYS different
smell ( or
looks) (=> aka custom case & 140 mm fan )
Cheers.
