From the manufacturer:

"As competitors have struggled to catch up to the performance and value of our phenomenally successful SeaBlazeX, Lumitec has jumped ever farther ahead with the introduction of the SeaBlazeX2. Available in dual-color white/blue or full-color Spectrum output, the SeaBlazeX2 delivers exceptional performance with over 6,000 lumens of output. The SeaBlazeX2 Spectrum delivers a nearly limitless palette of intense, vivid colors, complemented by a relaxing color cycle mode, and a solid bronze construction. It is surface mountable, has no external drivers, and a pedigree of reliability recognized the world over. The bar has once again been raised."
