The lights should work, but they won't illuminate the screen fully with an even & useful intensity, so growth won't be even.
The exact spectrum of red is not on the box but they are not 90W. They are 15 watts each. That's a total of 30W on one side of the screen, as you have set it up. A full mesh sheet is bout 130 square inches, so at 0.25 to 0.5 watts per square in of screen of 660nm, you need a total wattage of 32W to 65W.
