is 100w COB enough?

Hey Guys,

This is a double post (posted it in the newbie section and realized it should actually be here)
Sorry about that...

So i have found this locally - They are 50w COB Leds
It says on the one D4625 - 5810C
Would 2 of these each in a floodlight reflector work for a 3 x 2 foot area?
What kind of yield - ive read of COB doing 1.5 grams per watt - but could these ones pictured do that?

Please note - this is a personal grow. i wont be selling or giving to friends at all.
So i dont feel the need to go big. This is literally just to keep my own supply so that i don't have to buy shit weed from other people.



Thanks.

100W of good cobs do a lot more than 100W of those

not sure what those cost at but 50W each the $8 cobs on my site will outperform those

I have no clue about the bottom chip, but the top chip appears to be this

I cant see any mention of type of leds used,
will it grow stuff? Yes,
Will you get the 1.5 gpw you asked, I highly doubt it with this chip.

Just an estimate - how much per watt would this chip be able to do?
1gpw? 0.5?

if it sucks then i wont get it thats why im asking.

thats a loaded question

at 50W

with everything dialed

maybe 1 GPW

time you buy heatsinks and drivers cheap chips arent really a bargain

thanks for the advice.
Not gonna buy it then.
Let me rethink my plans.

Vero 29 gen 7's best bang fer yer buck 146-8 lumens per watt!!! cheapo shit will just make more heat per watt not more light.
