It may be that even though the lamps are rated for 3.5v that they are rated for lower current than the original ones, which would cause the new lamps to drop more voltage than the older lamps when mixed. <br><br>Peace,<div>Pat</div><div><br><div dir="ltr">Pat Horne <div>We support Habitat for Humanity</div><div><br></div></div><div dir="ltr"><br>On Nov 27, 2022, at 9:05 PM, Karl Vacek <stearman809@gmail.com> wrote:<br><br></div><div dir="ltr">

Shop content - as soon as I get the Christmas tree done I can go back to the shop and work on something.<div dir="auto"><br></div><div dir="auto">We have many strings of Christmas lights on the tree. <span style="font-size: 12pt;">Almost all are 30 year old plus Silvestri 35-light series strings. Silvestri calls for 3.5 volt replacement bulbs. Replacement bulbs were getting scarce locally so I ordered some from an Amazon seller, and some from a place that specializes in hard to find items. They're of two brands, all 3.5 volt for 35-light sets. Every one I install lights for a second and burns out immediately. They don't look overly bright as if they were for a lower voltage. Once burned out the string still stays lit because they have the same jumper as the originals.</span></div><div dir="auto"><br></div><div dir="auto">What am I missing?</div><div dir="auto"><br></div><div dir="auto">Thanks !</div><div dir="auto">Karl</div>
