The wellcrafted Halo (Crystal) lightsaber, known as the Kyber Heart, is an improved version of the Kyber Relic. It boasts a visible crystal chamber and a sophisticated dual-button control system, highlighted by a striking yellow accent ring. One notable feature of the Halo Crystal is its capability to synchronize the crystal's color with the blade. This can be achieved on Neopixel (SNV4 Pro and Proffie) configurations, where the crystal transitions through 12 distinct colors in perfect alignment with the blade. (Note: The crystal color does not synchronize with the blade under the RGB configuration.) The exclusive Halo Crystal Chamber lightsaber from SABERLIGHT is the ultimate choice for fans seeking advanced customization and control. For maximum creative freedom, opt for the Proffie version to unlock a wide range of color synchronization options between crystal and blade.
