light for 2x3? Kingbrite 240w?

I'm looking to get a light for a 2x3 tent because all I have right now are two 300 watt burples. I'm planning to just grow one plant at a time. I was going to get the 260w v1 kit from hlg because it was on sale but it sold out. Would this light work well for me? https://www.alibaba.com/product-detail/Kingbrite-3500K-Samsung-lm301b-Quantum-led_60804816911.html?spm=a2700.galleryofferlist.0.0.c5905cf1Jlpfc5

I read not to use epistar but I'm not sure I understand how much ppf or umol are needed. Does that look like enough? I was told by others it would work well for me.

KingBrite also sells boards with Cree 660nm reds. Just get that model. And yes that is MORE than enough for a 2x3. You'll want to dim it through the entire veg stage. I'm not sure 240w in 6sq ft (40w per sq ft) can be handled by a plant. You'll have to play with it and see. But that's why dimming is so wonderful. The powers there IF you need it!

Honestly, any QB clone you buy with either epistar or cree mono's is going to be a 'quantum' leap in efficiency compared to your old blurple fixtures.
The Meiju clone I run will grow trees so don't sweat it.
The fixture you listed would be perfect for that space.
