Are these cobs?

Xul · Feb 18, 2019

Hey everyone, based off a grow thread I saw here on RIU, I saw someone flowering their plants under a whole bunch of household led bulbs so i couldn't help but take interest and decided i want to try myself.

When I popped off the lenses to these led bulbs, it looks to me like mini cobs, just wondering if that's correct? The housing of the lights is metal and acts as a giant heat sync.

They're not cobs, no. They're low-mid power LEDs that have usually just one single diode in them. COBs have dozens if not 100's of diodes packed into that small circular area.

When i look at these, i see a bunch of tiny squares within the circle, i thought maybe these were tiny diodes within the circle.

It's still a mid power led. But it does have COB characteristics.

Theres guy on here that has like 200 of them lined out growing a sog. And it is impressive. Not very efficient but impressive none the less.

That's probably a r40 spot light. More than likely its a cree cob. But uses a shit driver. But it's a cob.

Here's the bulb here : https://www.amazon.ca/TCP-LED14E26P3030KFL-Dimmable-14-Watt-PAR30/dp/B005DST2RG

I very much doubt they are 14w. I use quoted 15w cob led screw in, when I checked it actually draws 5.5w.
They still grow decent weed tho

Yeah that's what I meant par30 flood light. I'd almost bet it's a cree cob. Like a smaller version of the cxa3050.

What say all of you led diehards about the RATED LIFE SPAN OF 25000 Hours??

Check the Cree Spec Sheet:
