We have a thread here for the EB strips. Cheap LED Strips : A Viable Alternative
Depending on if you are vegging or flowering with them or both. A 240W driver and 16 X 22 inch strips on the frame covering a 4 ft by 2ft area. One will be equivalent to a 600W HPS light. I have one and it works very well in veg and flower with 3500K I am just looking at building another.
Its easier to have 2 lights than one big one so you can have different height plants in the same tent/room.
Set your country for the correct price.
