Thinking more like box store, i.e. HD, Walmart. The Philips 60 and 100w replacements run really cool and you can redeploy them easily. You can pick up a couple of different temperature for about $10, good for a test.
Best COB (CXB3590) color temperature for flowering?

For flowering , take 3000k 80 cri top bin.
You can have 2700k too, i cant find datasheet for this one .
Yestarday i found this :

in order to add to my 4 cxb3590 3500k , but i dont know if its worth

you can fry eggs on those suckers. try unscrewing one with your bare hands!

So how the 3500k performed?

Even with a tiny bit of airflow it's already cool enough to hold it for a longer period and unscrew it. (the 100W)
Without it gets too hot to touch comfortably.
Just tested it with my own 13W (1521 lumen 2700K) bulbs.
20W Osram Parathoms aren't bulbs you want to touch.
Maybe with an airflow of at least 1 m/s, but they're pretty hot.
They're good bulbs though, little hotter than I really wanted but sockets can take a higher temp than the nerves in my hand.
They're also rather cheap, about the price per watt as a Gavita DE.
And I think by now they should be more efficient too, 117lm/w for the Philips bulb, that's including diffuser/PSU losses. Without diffuser it should be 130 lm/w at the least.

There is no Best just choices. My current board uses 3000k 90cri for flower works great for me. I also have a mixed 3500k/5000k board both 80cri

My preference is to go higher CRI for flower and lower CRI for veg. The more reds you can provide, the better. Also the higher CRI appears to produce a better profile. Another benefit being that it is more pleasant on the eyes to work under.
As for colour temps, I like using the 3000k as a baseline. For fast flowering shorter plants like indicas it might help to go lower during veg. Sativa dominant can handle higher to keep them shorter. However, I have found that if you do aggressive topping during veg you can get a good benefit using the 3000k having quite a few more flowering sites.
