After comparing Dialight's spec sheets dialight.com and Cree's cree.com it seems pretty likely to my engineering-challenged brain that Dialight is using Cree's Superbright blue and greens, and probably is using them in their "ultrabright" whites as well. Dialight's "ultrabright non-tinted, non-diffused (water clear)LED" specs indicate that their blue and green have the exact same peak wavelengths, the exact same typical and maximal forward voltages, the exact same reverse voltages and exact same forward currents as Cree's Superbright blues (Cree calls their 470 nm LED "Sign Blue") and greens (Cree calls their 525nm LED "True Green"). Dialight's "ultrabright" white LED also has the same electrical characteristics as Cree's superbright blue, suggesting it's a phosphor-coated Cree blue.
