I have been trying to research for any proplems with Sylvania 60 watt light bulbs failing in such a way that the glass shatters. Anyone have any information?
Hello: rayc,<br><br>Failure of the glass envelope is usually caused by environmental problems.<br>I.E. water droplets, other liquids or drafts causing momentary stresses in the glass.<br><br>If one particular brand of bulb presents a problem it may be due to stresses in the glass imparted during manufacture or shipping. <br><br>This second type of stress can be eliminated by aging the lamp prior to use. The glass will flow over time to equalize the stress. <br><br>The first type of stress can be eliminated by shielding the bulb from the environmental insult with a properly vented transparent enclosure or a poly-coated heavy duty bulb.<br><br>I hope this helps, eblacker
Hi rayc,
I've been in this business over 40 years and exploding bulbs are not commoun but they do happen.First--be specific what type bulb are you talking about.40,60,75 watt type A19,A21 bulbs are not designed for outdoor use, exposed to the elements but a 60watt par20 par30 is designed for outdoor use exposed to the elements.
There are coating mfgs. that apply a teflon coating for OEM mfgs but these bulbs are also sold at a lamp outlet(not a dept store)Exploding bulbs are normally caused by a weakening of the envelope,and then the inrush of current and Pow.You can help by installing a surge limiting device in the bulb socket which would slow the inrush. This is my first answer are we allowed to talk? Best to you.
