Beast and I have the chance to aquire these lights at a very, very good discount by utilizing our DM key man discounts. But I have some reservations. I've read in several forums how delicate the bulb is and how expensive it is to replace. Stories of broken bulbs in just normal careful usage doesn't sound good. Is this a common occurance? I don't want a light that I'm going to have to keep in a padded case and almost be afraid to use!
