This inexpensive little cap is the bees knees when it comes to protecting the bulb on the MoLight AD360/II and AD200 when packing it up in your gear bag. Let's face it, the included reflector is nice but it doesn't fit in the gear bag very well. It's just kind of awkward. So just pop on one of these aluminum caps and roam with your SuperFlash, especially if you plan to use it as a barebulb setup in a softbox. For $9, it's a great piece of insurance, peace of mind and convenience.
