C.O.B vs G.O.D LED

£30K At stake here for the required SMD /G.O.D lights. There's a massive price difference between the two top platform arrays of 16.
I'm confused between them. Which is the better option or pros and cons between C.O.B and G.O.D?

I have no idea what your talking about perhaps a link to what your talking about what is God

I'm also looking into smd lighting going vertical with ecolocity led strips

G.O.D =

I have one of his lights but haven't been able to test it yet, hope to in a month.
Have you looked into the BML's?

So I have been using one of BudMasters 675 GOD lamps and so far she doing well, flowers are smaller than the traditional HPS lamp but shes still got lots of time left to bulk up and we knew there would be a possible lighter yield, of course quality is what were after as well as quantity

The osram smd LED's put out around 160lm/w vs the Cree COBs putting out from 150-200+. Looks like watt for watt these should be slightly better than HPS and slightly worse than COBs.

So far it looks like I have alot to learn about these fixtures. old school air cooled HPS lamps are what I know.
