Just ordered a 150W Quantum Board, can I swap my Blurple UFO mid grow to the new board? Is it possible to increase flower size this late into a grow?

I have a 150w quantum board from a chiness seller , it's a 3500k with UV and IR , it was supposed to replace my 2 50w ufo "burple" light that was just fine for flowering. But I decided to plug both my quantum and my ufo's and the result is amazing because the "burple" light are bringing more blue to the spectrum that is giving me short internodes (except when I choose a high distance between the lights ans the plants , then it is stretching ) and the plant are shorter but bushier and like I said if you put the light higher then you will work on the height. Stop talking bout me : What is the nenefits of a QB ? Better spectrum and basiclu the real full spectrum compared to the purple light ( mostly blue and red ) , they are producing less heat than the other light without using fans for heat disssipation which leans they are noiseless and the fact that they are emitting less heat can allow them to be placed lower in height. The QB are made of a lot of little leds that covers a bigger "area" than the others boards and so a better light repartition than a COB or a HPS that are more efficient in the middle than in the corners ( the light will reach the corners of the box easily ). The QB wattage is also ALWAYS the real draw compared to the purple light so what you ordering is what you get. It will make a difference to the plants health ( to me ) as the spectrum is a higher quality one with the QB and the light repartition is more efficient
