Built for Mega Trees

With 12,750 pixel capacity, 700 watts of power, and native xLights integration, the MD1500 Baldrick17 is sized and spec'd for the demands of serious mega tree builds. Dual Mean Well LRS-350-12 supplies deliver stable, balanced power across all 17 outputs so your tree runs clean from base to topper, all season long.

This is the same controller platform trusted in Mattos Designs mega tree and show kits, purpose-built for the MD1500 enclosure ecosystem with Mconnect connectivity and 2-color PETG printed cable ID clips numbered 1–17 so every pigtail is labeled and organized from day one.
