It's a cool concept but I bet they get price prohibitive fast once the designers try to dial up the efficiency of the mini drivers and chips.

Yes, but how efficient is it? Is it dimmable? Enquiring minds wanna know! Lol

Maybe 100-110lm/w!?
With a controlled transformer or variac they should be dimmable via input voltage, but makes them even more inefficient.
If this continues, we'll soon see "dinosaur COBs", 2'x 4' COB's, Lol!
One COB - one tent, Lol!

Only if they get serious about better efficiency.

Dear Gentlefolks,
Has anyone tested them? I use a lot of cheap LED lights in my clonning/ sprouting area. They work ok but have not yet tried driverless cobs yet. I will try to post some pictures of my ridiculously inappropriate lights if you guys try not to crack up.
EasyPeazy yours,

They work fine. They're just hot and inefficient, so most don't consider them a viable alternative to better- read more efficient- chips and external drivers.

It's the classic trade-off of up front cost vs savings over the entire lifetime of operation.
