Upgrading LED Lights

I have two 2.5x5’s that are 6.5’ tall and a 3x3 all flower tents. My style is 2.5x2.5’ wide plants with 6-6.5’ height and 3x3x6 for the first time.

So nothing bigger than 3x3x6 or the other tents any time soon and thats fine. I love the results of them.

I had evolved a bit growing wise especially doing clone side by sides same plant. Using minimal lighting, knock off brands and now sufficiently with mars hydro.

They work perfect for 2.5x2.5 but dont like the hazard. I see now a viparspectra p1500 is the same footprint. I just read theyre safer, is it?

Im interested in trying them out after my mars lights run their course.

What are key differences between the two? Why do my mars lights produce the best quality and yield and how could it compare to VS P1500?

Using this thread to evolve my knowledge and possession of lights eventually to HLG but why? Ill leave it at that.

I have some understanding of overall like blue, yellow, IR and red lights and samsung chips, more expensive samsung chips. Top bin. Ive heard everything at least once.

Any links to things I can read to answer my own questions that would help.

My knockoff brand has all the same lights but something about the mars does grow better clones than the other light.

On other hand with the right hormone distribution my mini clones of 28 w for both of ACI bar lights samsung diodes created chunky buds. A structure I havent seen this clone grow before.

I have a 3x3 knock off brand its a fecida 230w I rather try growing with a VS and get to know them or others. Or another mars hydro.

Spider farmer I heard is owned by mars hydro. Are they any different?

I was thinking the same thing last night. I have a 60in by 32in and currently have a couple of QB96's and a small viparspectra and a rapid LED puck. Most of these are over 5 years old. I was looking at using 3 x Viparspectra XS1500 pro with the upgraded lens. in my tent. Three in line would make a continuous strip right across the full width of the tent. Or they would also work with the long side on the width of the tent.
