Anyone know why 1 string of Christmas light would start burning brighter?

Question

The one string of lights just started to burn brighter. After a few days, all of the lights were burnt out so I replaced them. Now that the string is working, they are still buring to bright. Any suggestions. PS...I do still have my Christmas tree up. Merry Christmas

Answer 1

There is a short starting in them.
You should get rid of that string as it could start a fire

Answer 2

You may have replaced the bulbs with bulbs of the wrong rating. Count the number of bulbs in the string, and divide that number into 120. That will give you the voltage rating of the bulbs to be used; if there are 50 bulbs, each should be rated at 2.4 volts, and all must be rated at the same current. Bulbs will start burning brighter when some burn out; it is important to replace the dead ones promptly so that the others don't blow out also. If they all do, you will need to replace the fuse in the plug because it will blow.

Answer 3

Well, there are a few fires every year. It's mostly due to shorts in damaged wire on old lighting strings. Modern lighting strings are very safe. They never generate enough heat to cause fires. I used to work for a firm called Underwriters Laboratories. They go into factories and test products right off the line for safety, both a design check and putting them through normal use and abuse. If they pass, they get to bear the UL label, which is a UL in a circle. Lighting strings use the holographic labels to prevent counterfeiting since all the strings are made in China. Just look for the UL Listing label and feel confident.

Answer 4

watts = amps x voltage = what ever the brightness is supposed to be normally. amps = voltage / resistance ( each and every bulb). Reducing the resistance increases the amps causing the lights to burn brighter. It stands to reason you have a short in that string of lights.
