As a side not, something that never happened to me with incandescents happened with halogens.  I refuse to buy anything with the mercury warning and noticed the halogen the was shaped like an incandescent in the 60 W replacement size.  I bought it and had it in for about a week.  One night I hear a &quot;boom&quot; that wakes me up.  It sounded like a muffled shotgun.  I walked into the living room to discover[1] the halogen had blown up scattering little glass shards all over the living room.  I was not happy.<p>I went out and bought a cheap LED from Walmart[2] which seems pretty good and turns on right away.  I do wonder who is the actual supplier.  No heat, bright, and hasn&#x27;t blown up.<p>We still have a couple of packs of incandescents at work because we use the chicken coop method of heating a box outside during the winter.<p>1) well my foot discovered this which required first aid<p>2) <a href="http:&#x2F;&#x2F;www.walmart.com&#x2F;ip&#x2F;Great-Value-GVRLA6027ND-Great-Value-LED-Light-Bulb-8.5W-60W-Equivalent-A19-E26-Soft-White&#x2F;40507614" rel="nofollow">http:&#x2F;&#x2F;www.walmart.com&#x2F;ip&#x2F;Great-Value-GVRLA6027ND-Great-Valu...</a>
