COB LED Discussion

[ReeferMadnezz]

Hello.

Has anyone done any grows with the COB style LED's? I've started incorporating them into my hobby grows but I don't have a ton of empirical data yet as to the results. They're pretty easy to put together and seem incredibly bright. Just wondering if anyone out here has any experience with them.

I have ditched the blurple for CoB and Chilledlogic Pucks.

To date:
I have finished a previous grow with them and have almost completed a grow from seed.
The most noticable thing is the bud quality under these lights are amazing!

I am finding a bit of a learning curve, in getting the correct distance for seedling and flower.
It does change the grow environment as they run cooler, etc.

Check out member- mcubed476 for some insane grows with 55w CoBs.

I went and looked at mcubed476 and some of his work. He does good work with those 55W COB. I would have thought 55 was a bit lean for the space he grows, but his results speak for themselves.

i used some COB leds.full spectrum and blue.it's awesome.just don't use lenses.much better than SMD

[Mohsen228]

i contacted the manufacturer and they recommend not to use Lens because it changes some light spectrums.

Oopsie. I thought when you said blurple, it was a play at the color of the light. I didn't realize it was a brand. I don't own one of those, I'm making mine from cheapest version of all parts from the ebay. Going to be some fun science.

mine is cheap Chinese one too.lol.doesn't matter.lens is not good for growing.use reflectors instead

Here's my first 100W attempt from the underside.
