Is it better to connect Christmas lights in series or parallel?
Series Lights. When lights are attached in series, the electricity passes from the power source to the first light, and then from light to light until it returns to the power source. When lights are attached in parallel, each light is on its own circuit to the power source.
Why do half of Christmas lights work?
If half a strand is working and the other half is not, you probably have a loose or broken bulb. If not, you have the more tedious job of going down the row of unlit bulbs, one at a time, and swapping them for a known, good bulb until you find the culprit. You’ll know it when the strand lights back up.
Can you take lights off pre-lit tree?
Is it possible to change the lights to save money in purchasing a new tree? Can you take lights off a pre-lit tree? This will have to depend on the kind of artificial pre-lit tree that you have. Some trees are pre-wired and strung with lights embedded within the artificial branches and cannot be removed.
Does Light Keeper Pro really work?
After reading the instructions several times and getting a feel for the proper angles to hold the tool while it’s activated, we found the Light Keeper Pro did work. We quickly found the burnt out bulb in two light sets, and repaired the circuit in two others.
Does Light Keeper Pro work with LED lights?
The LightKeeper Pro’s Quick Fix Trigger will only work in series Miniature Light sets with shunted bulbs. The LightKeeper Pro would not be appropriate for the larger lamped C7, C9 sets, tube/rope lights or LED Lights. The control box will block the pulse before it reaches the defective bulbs.
How does the Light Keeper Pro fix Christmas lights?
How LightKeeper Pro Works. Defective Bulb shunts cause most light set failures. Simply plug your LightKeeper Pro into the light set and pull the trigger. The LightKeeper Pro sends a pulse through the light set, finds the bad bulb, and fixes the shunt—allowing the light set to work properly.
What is a bad shunt on Christmas lights?
In incandescent holiday lights, shunts are small wires wrapped beneath the filament.) If a bulb’s filament breaks, the shunt redirects current through the base of the bulb, maintaining the electrical circuit. A faulty shunt may sound like a catastrophic failure, but you can often fix it with the LightKeeper Pro.
Can I cut 3 wire Christmas lights?
Short Answer: No, you can’t lengthen or shorten standard series-wired incandescent and LED Christmas tree light strings that are made with 2 or 3-wire harnesses. Even if they work at first, they won’t last long.
Why do LED Christmas lights fail?
If one of your LED light strands isn’t working, it’s probably just because it has a bad bulb. If one bulb dies, it can cause the rest of the strand to stop working. The only way to fix the problem is to find the bad bulb. That means pulling off each bulb, replacing it with a good bulb, and plugging it in.
Do Christmas LED lights burn out?
LED Christmas lights use light-emitting diodes, rather than filament, to produce light. This makes LED lights more efficient, durable, and longer-lasting than fluorescent incandescent lights. They don’t burn out, like other bulbs; and they also don’t get hot to the touch, so they’re a lot safer, too.
How many hours will LED Christmas lights last?
200,000 hours
