It is that easy. Those screw are for the cob holder. Shouldnt have to mess with anything else.
Just get some thermal paste for under the new led.
3500k would be better than those 6500k ones if thats what you have.

I have 5 200 watt 4 cob bars made with 3070 over half my room and 4 250 watt 4 cob bars made with 3590 over the other half and I can’t tell a difference between them and yes there are interchangeable
been running 3070 for about 5 years and 3590 for about 4 years

Yea newer then the 3070’s
the 3590’s weren’t out when I started building my bars but came out shortly after.
it took me about 2 years to acquire and build the bars replacing 600 hps as I went. it cost to much then to do all at once

Heat is the enemy of LED systems. It degrades effective life.

Makes those heat sinks more understandable,,eh?
