<div dir="ltr">One other things I don't think a lot of people consider when buying LED bulbs: Make sure for indoor use within enclosures, you buy "Enclosure Fixture Rated" bulbs. Many of the cheap bulbs that have the 5 year warranty are NOT rated for enclosures, and the heat will damage and prematurely kill them. I've had many old LED bulbs not last a year when they were warrantied for 5-10 years, but on closer inspection, they were not enclosure rated. In my kitchen, when the bulbs die, the plastic base usually cracks due to the heat.<div><br></div><div>Possible that the bulbs you have are not rated to be inside enclosures, and the heat is killing them, hence the burning plastic smell. Could also be the cheaper bulbs are using cheaper plastic, which has a lower heat tolerance, and causes the burning smell.</div><div><br>Hope that helps.</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Sun, Jul 13, 2025 at 9:23\u202fPM CrankyOldBugger <<a href="mailto:crankyoldbugger@gmail.com">crankyoldbugger@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>I've seen LED bulbs get hot.

<br>
Do you smell "burnt plastic" from your LED light bulb?<br>
If not, then what brand/store are you using?<br>
<br>
Background:<br>
-----------<br>
For longest time, I've been smelling "burnt plastics" in the house. At <br>
first, I thought some neighbour's wood stove... exhaust goes up, drifts <br>
over to my house, cools, and comes down. But, it's more "plastic" <br>
burning, not "wood" burning. It's bad enough to irritate my throat and <br>
interfere with my sleep. I've been opening all my windows at night, daily.<br>
<br>
I checked everything... water heater, furnace fan, refrigerator, my <br>
computer. I finally found the culprit. LED bulbs. The plastic base <br>
gets hot and emits that smell. Over time, it accumulates inside the house.<br>
<br>
All my LED bulbs were bought from Canadian Tire. So, I bought 2 bulbs <br>
from Home Depot (Ecosmart) and Rona (Valu+). And, they don't smell, at <br>
least after 1 day of use. Maybe it's too early to tell.<br>
<br>
I'm on the verge of going back to incandescent bulbs. Help!<br>
