Morimoto’s XB Ballast are a functional work of art. While the industrial-edge design by California native Artur Saakyan looks great from the outside, they’re packed with too much modern tech on the inside to cover it all in on place. Their DSP 3.0 circuit maximizes reliability, input and output efficiency. Their ability to warm the bulbs up to full operating intensity quickly is matched by few. Hardly are all aftermarket-HID ballasts the same, and the XB’s make that clear in most every category in our opinion.
