Depends on your application and preference below are some key differences between Jetusolis and Jetue21a:

  • Jetusolis designed to give the most neutral natural CCT with minimal tint shifting (tightly lies near BBL). No greenish nor pinkish, just neutral.

  • Jetusoli...

*Please note that this guideline is based on my personal experiences dealing with various (mostly) Nichia LEDs.

What's your preferred CCT?

In general, there are two broad category for white LED: warm white and cool white. As for Nichia LEDs the warm white (1800K - 4500K)...
