Bulbs arrived quickly and match my flashlight perfectly. The original lamps lasted over 20 years. None of the ones I've bought have broken yet so I can't comment on their longevity - I hope they last 20+ years too! These bulbs are incredibly bright and incredibly hot. Make sure your fingers are free of water, grease, or hand cream before touching the bulbs. Ideally, do not touch them with your fingers at all, but use gloves. Also, do not turn on the light while touching the bulb.
