From the last one, which I found informative;
For instance, colour tuning of 2,250-2,950K can be achieved with an R9>90, CRI>90 and efficacy of 90 lm/W using Luxeon Z combinations. When using a similar combination of red, green and blue LEDs to create 3,000K white light, the CRI is close to 20,” claimed the firm. “Alternatively, tuneable white light with high efficacy can be achieved from 1,800-6,500K along the blackbody curve.” Lime is the highest efficacy Lumileds LED manufactured to date, some devices hitting 200 lm/W at 350mA and 85°C (Highest bin is 190 lm/W typical). The company tests Rebel ES Lime LEDs at 350mA/85°C, while the equivalent royal blue and blue are tested at 700mA/25°C. All other Rebel Color emitters are tested at 350mA/25°C.
