Didn't think so but I was just makin sure..
I know sfa about LED's....but curious to see if its worth it $$
Soldering is not required most of the time. WAGO connectors make wiring simple. Someone here even makes Junction boxes.
If you can wire a Christmas tree none of the wiring will be a challenge.
Pick a COB and driver combo from the list of 'approved' combinations that many have tried and found true.
It's that simple. What you get when you buy the same combinations of parts from Tasty LED or another reputable builder is expert assembly, attention to detail and a warranty. That's well worth the additional cost if you aren't comfortable with DIY or just don't have the time.
To your last point; COB LED runs cooler, produces more bud per watt with higher quality. Even if it didn't save a dime in electricity it's worth it.
I'm also testing the Revolution Micro DE HPS fixture and while it's a nice light, it and all other HID lighting options are very simply outclassed by COB LED.
