I just switched from an HID to LED. The HID gave out eventually (the bulbs don't last forever) - 3 years ago when I bought it, it was definitely the right choice. Now you can get LEDs that put out about the same amount of light for about the same money, and the LEDs are much more versatile (many power settings, strobe modes, etc) and should last a lot longer. Also they should get longer runtime for the same amount of battery, they're a bit more efficient.
