I’ve been building LED lights for few years. Have given away or sold a few previous builds, but the current build with Bridgelux EB3 2700k 90cri strips is totally rocking it.
The spectrum has as much red in it as an HPS, but has enough blue and green to also keep the plants compact while not restricting their growth (which too much blue can do). The color of light is very pleasing to the eye. Here’s independent goniosphere testing of the diodes in the strips I used.
Whole build thread can be found here: A total nube's DIY LED build 🛠 Here’s the most recent harvest of 4 plants organic, water only, in a 4x4:
Also, still using a DIY 400w Cree 3500K COB fixture for veg when I’m able to put up a separate tent.
I sold this to a friend a few years back, but then they ended up borrowing a couple grand and, when they couldn’t pay me back, I offered to take back this light and call it even. No, it’s not worth that, but it was a nice thing to do. And it still works great after 6 years and a lot of travel + abuse.
LED are the way!
