Yes, if you are replacing an HID lamp, you must bypass the ballast and wire the AC power directly to the lamp socket. Bypassing the ballast is important because the LED operates on direct AC power and does not need the additional components required by HID lamps, simplifying maintenance and reducing energy consumption.
