You are only specifying one light in your array.
x*10, y,10, 1 = 1 light
Should be like these examples:
x*10, y,10, 10, 1 = 10 x 1 = 10 lights - 10 in 1 row
x*10, y,10, 5, 2 = 5 x 2 = 10 lights - 5 in 2 rows
x*10, y,10, 5, 5 = 5 x 5 = 25 lights - 5 in 5 rows
x*10, y,10, 4, 10 = 4 x 10 = 40 lights - 4 in 10 rows
