Method of manufacturing a cordless lamp

Open the bottom of the lamp

Turn the bulb over and find its wires. If the wires are not easily accessible, carefully pull the lamp pot to expose the electrical wires. Be sure to select the correct polarity when locating the wires. In addition, the bottom of most lamps is always equipped with a piece of felt. However, this should not be a cause for concern as it comes off easily.

Remove the top part of the lamp

After opening the bottom part of the lamp, the second step is to remove the top part. You need to trace the wires connecting the lamp to the power source and carefully remove them. Disconnection can be done with a small screwdriver or with your own hands. Then cut the wire from the lamp, leaving a distance of 20 cm to the base. Be sure to locate the nut on top of the bulb and unscrew it. Also note that every bulb is different, but there is always a way to unscrew the nuts to remove the cover.

Separate the wires of the cable about 15 cm from each other. Strip 1.5 inches of connector insulation from each wire, focusing on the insulation on the two wires.

Unscrew the electrical unit

Use a screwdriver to release the electrical unit from the lamp. Be sure to identify the original location where the cable was connected to the electrical wiring inside the unit. You will find two wires (red and black).

connect the wires

Using wire cutters, cut about a half inch of battery wire. Connect cables with the same polarity. Connect the positive lead from the light bulb to the positive lead from the battery by crossing the two wires. Then connect the negative lead from the light bulb to the negative battery terminal. Wrap exposed wires with electrical tape.

Check battery polarityHow to make a cordless flashlight - Cordless Guy (2)

Put the batteries back in the battery compartment and insert the battery into the battery compartment. The battery will still work if it is connected with the correct polarity and if it does not fit in the case. Check that the positive and negative poles are positioned correctly. Turn on the flashlight to check if the battery is working. If the lamp lights up on battery power, you have correctly created a wireless lamp.

You can repeat this process if it doesn't work the first time.

Can an electric light bulb be converted into a battery?

The process of converting an electric light bulb into a battery is quite simple. You can use simple household tools to remove the electrical wires from the lamp and replace them with rechargeable batteries. The advantage of using rechargeable batteries in your lamps is that you can light every room in your house with the same intensity and quality, as there are no cables to limit your mobility.

Follow the steps below to conveniently convert your flashlight to battery.

Localize os fios

Find the electrical wires in your lamp by turning it upside down. In some cases, it can be difficult to identify the location of the wires that connect to the lamp's electrical circuit. However, this shouldn't be a problem. You will need to carefully pull the bulb out of the housing to expose the electrical unit and locate the wire connections.

disconnect the wires

Once you've found the wires, disconnect them from the electrical unit. To disconnect, you can use a small screwdriver or just by hand.

Make sure you have a 6 volt rechargeable flashlight battery. The battery must have both AC and DC cables connected.

Find the first connection points

In this step, open the lamp's electrical unit using a screwdriver. Determine the original connection points where the wires were connected to the electrical unit. See if you can find two small copper wires with different polarity, positive and negative connections.

Connect the cables to the battery

The bulb wires have (+) and (-). Connect the cable marked (+) on the lamp to the cable marked (+) on the battery cable. Twist the wires together. This ensures that the positive pole of the battery is connected to the positive pole of the cable.

Also, connect the wires marked with a minus sign (-) to the battery wires, also marked with a minus sign (-). You have to connect the negative poles again. Wrap exposed wire connection points with electrical tape.

Replace the lamp housing

The last step in the process is to replace the lamp with its unit (housing). You can install the battery in the compartment if it fits, especially in the hollow part of the lamp compartment. However, if your lamp housing does not have enough space, you can leave it free. It will still work effectively.

Common questions

Can you turn plug-in lights into batteries?

Connect the lights to an AC to DC converter powered by a 12 volt battery. The battery power source is created simply by cutting the wires and reconnecting them to the battery. Connect the battery harness wires to the exposed wires by twisting them together. After twisting the wires, cover them with electrical tape.

Why don't magic lights work anymore?

Fairy lights can stop working for many reasons; A bad bulb, broken filament, blown fuse or bad shunt can cause a malfunction, broken filament or bad shunt. The shunt allows current to continue flowing even though the filament has broken, creating less resistance than the original path, allowing the string of lights to continue to shine. A faulty shunt will not redirect the circuit to the lower bulb if the bulb burns out.

How long do USB fairy lights last?

USB flashlights generate light using light-emitting diodes instead of filaments. These diodes make string lights neater and last longer than incandescent fluorescent lights. The USB fairy lights don't get hot to the touch, which makes them much safer. They have batteries called microdrops or firefly lamps, with intact wiring. These fairy lights last over 100 hours on fresh batteries. Fairy lights can stay on for 6 hours. A standard AA battery has a capacity of 2000 to 3000 mAh and can last for 45 to 100 hours.

Do fairy lights burn?

With a modern mini light chain, the light stays on even when the bulb is turned off. The light string remains on even if one of the lights in the string burns out. Replace the burnt out bulb as soon as possible to prolong the life of the remaining bulbs in the series. If a bulb in the series is faulty, loose, or misplaced, the circuit is fragmented and the series will not light. With some fairy lights, the sequence may fail if the bulb is burnt out.

Most modern, better quality bulbs have an extra wire called a shunt that acts as a backup if the string fails. The shunt keeps current flowing to complete the circuit whenever the filament burns out. The shunt does not always work perfectly. This is the membrane that should come off if the filament fails, but it doesn't. A repair device like the Lightkeeper has the advantage of sending an electrical spark through the circuit to destroy the plating and activate the shunt.


The lamps have miniature bulbs (50-150) depending on low voltage wired lighting. Household voltage is relatively high for a series of lights; Therefore, small light bulbs are connected in series to operate at a higher voltage. Electric current flows through all the bulbs and completes the circuit. Cordless lamps are more reliable than their wired counterparts because they can be easily moved around the house. All you need are common household items like wire strippers, a 9-volt battery, battery clips, a flashlight, and electrical tape to turn your wired flashlight into a cordless one. To do this, you need to remove the output cable from your flashlight and connect a rechargeable battery to it.
