4x4 Veg light suggestions

I am looking to build a 4X4 veg light and was going to do the CXB3590 but i seen they are no longer the best. Anyone have any recommendations on what will be a good cob to run? If i can get the same efficiency and not spend 40 for each one that would be great. I am looking to run them around 1.4A i will probably be building 4 of these in the end for a 8x8 area.
