Well I have 4 Delta bravo Cree and 4 citizen 1212s on a frame that seems to grow decent or is that light better then a Diy this is my second build I bought a kit from timber and had the 4 citizen cobs on a frame and had other Cree on another sell I wasn't using the Crees so I just used the Cree frame I already had and modified the citizens in with them and seems to work good so far
