Can There Ever Be Too Many Holiday Lights?

It is that time of year again where many people have decorated for the Holidays!  Twinkling lights are shining on rooftops, trees and all over the lawns of our friends and neighbors.  Most people know that one person that makes it their mission to have the most beautiful and colorful yard in the neighborhood. If you don’t, you have probably seen the movie National Lampoon’s Christmas Vacation staring Chevy Chase!  What lots of people don’t think about is how much power all of their lights consume and how much is too much for the extension cord, outlet or electronic device that they have the lights plugged into.

Every electrical device has a voltage and maximum power rating. The amount of power it takes to light a string of holiday lights varies depending on the type of light and the number of lights in that particular string. For example, a typical 300 light string can consume 72 Watts of power.   How many Watts of power are your lights, holiday decorations and devices rated for?

Our investigators at Blaze Fire Investigation and Anderson Engineering were involved in an origin and cause investigation of a holiday light device that synchronized the twinkling of the lights with holiday music. This particular device had a maximum power rating of approximately 400 Watts. Burn patterns pointed directly at this device as being a possible cause for this fire.

 

Our team of origin and cause experts and engineers examined the evidence, performed testing on exemplar products and were able to determine that the origin of the fire was internal to this holiday lighting device.  Testing results showed the over wattage of the device could cause a component inside the device to fail in an unsafe manner and ignite the flammable plastic housing of the device without tripping any circuit breakers in the house or blowing any fuses in the device or holiday lights themselves. 

 The Result for our Client:

Because of the detailed analysis and collaboration with in-house engineering, we were able to successful determine the origin and cause of this fire and determine the exact component inside the electronic device that failed and caused this fire.
