how many light bulbs does one rechargeable light bulb save



  1. 0 Votes

    The longest life for rechargeable light bulbs that I found was 50,000 hours. A normal light bulb is said to have a life span of about 900 hours:

    50,000/ 900= 55.55 (normal light bulbs)

    Magic Bulb is one company that is making rechargeable light bulbs.  The life span of their light bulb is somewhere around 20,000 hours.  They are also break resistant and they do not heat up.  The average light bulb last about 1000 – 2500 hours.  That would mean that this reachargeable light bulb would last 20 – 8 times longer than an average light bulb.
