I've grown under the purple lights. Built a nice one.
Then I started reading about cobs and, like you, I didn't want to spend tons of money and be disappointed. So, I bought some cheap citizen clu048 chips, a cheap active heatsink, a couple of passive heatsinks and a cheap Chinese driver and made these.
Now, there's seriously no comparison in the purple lights and the COBs. I'm even driving the COBs at half the power, using a cheap driver and the growth is seriously ridiculous. I did decide to order a better driver after seeing how well they grow. I think you'd love the cobs if you like the purple lights. Now, I've only vegged under the cobs but damn they make for happy plants.
These are under a 400w MH and 90w of COBs in a 4x4 tent.
Oh yea, I took the lenses off the one light.
