An electric cord with many light bulbs at regular intervals along its length is called a string of lights. When something is decorated with such a string, it is said to be strung with lights.
You can find string light replacement bulbs for outdoor patio lights at home improvement stores, online retailers, or specialty lighting stores. Be sure to check the size and type of bulb needed for your specific string lights before purchasing.
The C7 range of christmas lights are 5 Watt bulbs which are 2.125 inches tall and 0.875 inches wide. The C9 range of christmas lights are 6 watt bulbs which are 2.875 inches tall and 1.125inches wide.
Overall brightness (not individual bulbs' brightness) will increase when we connect them in parallel & it will decrease when we connect them in series.
The wattage will depend upon the type of bulb and the number of lights on the string. It will tell you on the package what each bulb requires in wattage, so you only need to multiply that by the number of bulbs in the string. so, number of bulbs x wattage requirement for each bulb = wattage requirement.
PartyLights sells globe string lights online. They offer them with clear, white, or multi-color globes. They come in strings of 10, 15, 25, or 50 bulbs.
The best outdoor deck lights string options for creating a cozy and inviting atmosphere in your outdoor space are LED string lights with warm white bulbs, solar-powered fairy lights, and Edison bulb string lights.

These are old generation lights. They are connected in series with each other. This means if one of the filaments in any one of the bulbs opens the circuit current flow stops. For example if each bulb is rated at 2 volts each then a string of 60 bulbs can be on a 120 volt circuit. lamps connected in series, because each bulbs filament resistance is the same, will will drop a voltage across each bulb by the total number of bulbs in the string divided into the supply source voltage. 120 volts / 60 bulbs = 2 volts per bulb.Newer sets of lights have a have a spring mounted in each lamp. When any lamp filament opens a spring is released and shorts out the two wires where the filament was. This allows the string of lights to remain operable. This has a drawback in that as more lights burn out the voltage becomes higher across the other bulbs. Eventually the bulbs will start burning out faster and faster as the voltage across each bulb becomes higher and higher. Use the equation above to see this fact.Christmas string lights today use LED bulbs which last many times longer than an incandescent bulb in the string set.
It would really depend on how many lights on your string and which bulbs you use. Led bulbs are much more cost effective and cheaper to run, although the initial outlay is more. A 200 bulb string using 140W and on for around 10 hours a day would cost around £70 a year, a similar set using LED bulbs would cost around 90% less per year.
the lights seem to run for 3 days then they blow a fuse when i have tested all bulbs they are ok
The load on a string of Christmas lights is typically located in the bulb itself. Each bulb is designed to produce light and consumes power when electricity passes through it. The collective load of all the bulbs on the string determines the amount of power required to illuminate the lights.
on some cars the tail lights and brake lights are totally different bulbs gain access to the bulbs and have someone push the brakes so that you can determine which bulbs are the brake lights and replace the tail lights
