The GVM-SD400B Bi-Color Spotlight stands out with its impressive brightness of up to 400W. Unlike conventional two-color temperature spotlights that rely on different lamp beads to adjust the color temperature, the GVM-SD300B employs a brand-new algorithm for continuous lighting.

With this new algorithm, the GVM-SD400B takes into account the color temperature and color adjustments of various lamp beads, automatically calculating the appropriate power to maintain consistency across different color temperatures and colors. This ensures that the brightness of the spotlight remains constant even when adjusting the color temperature.

In conventional spotlights, variations in power can occur, resulting in inconsistent brightness levels across different color temperatures. However, the GVM-SD400B's algorithm resolves this issue, guaranteeing consistent brightness regardless of the selected color temperature.
