Title: Worst choice - useless
Review: I bought couple of these and for both I noticed they quickly deteriorated after couple of weeks. The lamplight became dim and I was wondering if I am slowly getting blind. I examined the bulbs and noticed the tube tarnished inside by a mirror-black residue - presumable film from metal evaporation, because it was not there when I bought them. When you turn the light on, it takes couple of seconds to light up, when turned off - it continues glowing for up to five seconds. This is not how halogen bulbs should be!I replaced the Feit bulb with another brand and guess what? The non-Feit 150W bulb is BRIGHTER than the Feit 300W!Do not buy Feit halogen bulbs.PS. no, the tarnish was not due to fingerprint residue - it was all over the bulb, not localized spot. the new brand i tried was GE Edison if i remember.
