X2 series bulbs are the absolute brightest bulbs we make and that’s saying something as an LED performance lighting brand. X2 series bulbs produce a stunning output that’s brighter than a 35W HID system and 5x brighter than a stock halogen bulb. We utilize the very latest chips and technology and keep everything humming with smart thermal management. Bulky fan cooling LED bulbs have become history. The X2 series is designed to be compact enough to fit in the tightest spaces. If you want X2 series brightness to slice through X2 series darkness, these are your bulbs.
