I can't stand how cheap modern lights are... and it seems like they overdrive the lamps to make them whiter... then they burn out after one season. And the C6 / C9 lamps you can get now are all junk.
I have several old strands of lights saved up, most still have vintage lamps in them. They hare really great color
I "worked around" the problem buy buying LED lights. The ones on the bushes and hanging in the front window are 3 seasons old, no failures
I need to crack out my meter to confirm, but I think the whole display takes about 100 watts.
