Far red supplemental lighting

[MountainBudz]

I have been reading about the Emerson effect on cannabis and am interested in adding some supplemental lighting to my current setup. I have 2 HLG 320 xl v2 rspec in a 5x5.
They sell a 60w red supplemental light but it includes all 3 reds and also some blue. From what I have read is that they had a deep red and far red strip that was called a qb 18 red supplemental lighting but the links I had found were dead. I just asked HLG why they make them with blue now and am waiting to hear back. Their stuff is pretty expensive though. Does anyone here know of any alternatives? I found a few cheaper options but they were sold out.

I've been looking at the kind led bars. They make some 4"-2" bars made just for flower or veg. Also optical 2 i'm considering for a supplemental light. I think both lights have uv, and IR which i find interesting. I'm looking to make a move for black friday so if you see anything interesting please post back.
