Yup I've heard good things about Meijiu as well. It just didn't make sense for shipping only 3 boards for me but I would have considered it had it been a larger order
3 boards is not enough. 1 bet a 8 board setup would be cheaper even with the shipping. We use lm561c since they are only about 80$ for 800 diodes, and the performance is similar to lm301b. Especially with a setup which really covers your cannopy.
Why 8? They would cover the cannopy almost entirely which means you can bring it right down to the cannopy which is important with open space as a high hanging fixture will lose light on the sides. Its also a very even cover.
And using 8 boards: you can run them at 150w or less, meaning they are at nominal or less. The electrical efficiency gains plus not wasting light on the sides, plus having the boards at just very little over ambient: all of this contributes to being able to get great results from 30w/ square foot i stead of 35-40. Infact you could opt for 2x 480w drivers.
The one thing with a fixture like this is that you have to make a frame which is as easy as buying alu L-channel and drilling and screwing a few holes. The connections are easier: just 8 units to hook up.

Yeah you're in the right ball park. The rapid setup is a good value. It's very modular and future proof as well. 900+ watts of the most efficient and well tuned spectrum LEDs out there should do great in your room. I dealt with CS too (just a general question) and they were friendly and quick to respond.
If you want a better value, I'm afraid the only other option would be to DIY or go with a Chinese qb clone but whether that's worth it or not idk.
Id say its worth it. Especially for an open space.

I really appreciate the time to put together your recomended setup. Even though I've been growing a long time and we'll versed in my current setup....I really am just in the learning phase of led's. There is so much info it almost seems like a foreign language. I want to make sure I get quality being that I would be transitioning from a tried and true hps setup. There are those that tell me I'm crazy to change but it appears technology has made strides in led's making it attractive. If I were to put together a setup like you suggest where should I look for the parts? I was totally set on a prebuilt fixture until I realized the savings in self assembly as well as getting better components. I'm honestly leaning towards the rapid kit as it looked doable for me and it has everything I need together. The longer and deeper I look the more I change my mind....lol....
You could get everything (except frame) at meijiu:

Parts list:
8 Fotop lm561c 3000k 80 cri
Assorted wagos from 2 -5 way: 20 x 2 way , 10x 3 way 4way and 5way (they arent all necesary but good tonhave around, especially at china prices.
2x hlg600h-48; use A o B according how youd wanna dim. You could probably also do it with 2 hlg480s. Id get drivers locally for warranty purpose, also no big savings on getting them from chjna.
Aluminium L-extrusions, 6feet long: 2 per bar, so 8. Get sturdy ones cause of ther length.
No heatsink needed as you will stay below 150w per board.
