The Vero 29 and the CXB3590 have very similar spectral characteristics. They do differ in a couple of respects:
1. Cree does binning, whereby they test the COBs during the manufacturing process to assess lumen output and efficiency. This code is called a bin code - we purchase top binned Cree CXB3590. Vero29 are not binned.
2. The Vero 29 COBs we use are a high efficiency COB, running at 100 watts/COB vs 50 Watts/COB in the case of the Cree, generating very similar efficiency. This makes the Vero29 lights a slightly better value as they require less materials for the same power output.
