Replace LED Bulb In Desk Lamp - Step By Step Guidance

Without further ado, let's start analyzing the LED bulb replacement process in detail.

Things You’ll Need

Here are some needed tools and materials you should prepare before getting to work: 

Item	Usage
Screwdriver	Unscrew and loosen the connection or vice versa
New LED bulb	Replace old bulb (make sure it is compatible with lamp)
Insulation gloves	Protect yourself from electrical shock, bulb heat, and shards of lamp
Dried cloth	Clean the lamp socket and replacement area

Step 1: Examine the desk lamp

The first thing to learn about how to replace an LED bulb in desk lamp is to examine the lamp to see:

Inspect the fixture for any visible damage or wear, if you notice anything concerning, consulting an electrician before proceeding is better.

Identify how we can access & replace the bulb by determining whether the bulb is removable or not, and then give an overview of how to reach the bulb (by simply sliding your hand into the shade and grasping the bulb or removing the shade first to get a better grip on the bulb). Otherwise, if your desk lamp has a fixed bulb, check whether you can access the bulb from the base or top of the lamp or not.

Check what type of old bulbs to replace by reading the code on the old bulb or check the side of the desk lamp base to know bulb type, socket size, or particular wattage, and consider if we can switch to an LED bulb or not.

Step 2: Choose replacement LED bulbs

Here are some recommendations for your ideal LED bulb to replace: 

1- Check for compatibility

Ensure that the new bulb matches the old bulb’s type and size, wattage, and voltage input. If you have a dimmer switch, ensure that both the LED bulbs and the dimmer switch are compatible with each other to adjust the brightness flexibly according to your preference. Look for a mark or label on the bulbs, and read the manufacturer's information.

2- Choose color temperature

LEDs come in a wide range of color temperatures. However, to get the best lighting effect for studying and working, LED lights should mimic natural sunlight and should be from 3500K to 6500K.

Color temperatures and their lighting output: Warm white light (2700K to 3500K) with yellowish or reddish illumination; Neutral light (3500K to 4000K) with natural brightness lighting, Cool white (4000K to 5000k) with bluish or whitish lighting, and Daylight (range from 5000K to 6500K) with natural sunlight.

3- Consider the lumen needed

The higher the lumens, the brighter the light bulb. Different LED lamp types have their own lumen requirements to serve various lighting purposes. Optimal lighting for general purposes like reading, writing, and working (on computer) ranges from 450 to 750 lumens. In addition, consider opting for an LED bulb with a lower wattage but a higher lumen output to benefit from energy savings while maintaining the desired brightness.

Step 3: Disconnect power source

Keep in mind that your top priority is your safety. To avoid any risk of electrical shock and accidentally damaging the desk lamp, remember to turn off and unplug the desk lamp from the power source. Double-check with the voltage tester, and verify that there's no electrical current running through the wires connected to the fixture.

Don't touch the light bulb right after turning the lamp off, or you'll burn your fingers. Wait a moment for the cool-down period.

Step 4: Remove the lampshade and the old bulb

If it’s hard to reach the old bulb, first you have to remove the lampshade. Use a screwdriver to remove any screws that hold the lampshade. In some cases, you have to disassemble the whole lamp. Then follow these movements:

• Grasp the bulb:  Use your dominant hand to carefully reach the old bulb and then grip it with your finger. Shouldn’t hold it too close to the top which may cause the bulb to crack in case of too much pressure. Remember to let the old bulb cool down before touching it.
• Loosen the bulb: Gently apply force to the bulb by turning it counterclockwise to loosen it in its socket. Keep turning the bulb until it comes loose in your hand.
• Discard the bulb: Delicately get the bulb out. Then you dispose of it properly or keep it if you want it as a reference to buy a new one.

Step 5: Install the new LED bulb

Before installing a new bulb, use a dried cloth to carefully clean the lamp socket and surrounding surface as well as the working area. Then take the new bulb and guide the stem of it into the socket of the desk lamp and ensure it is securely seated in the place. Gently twist the bulb clockwise in the socket to tighten it. 

Step 6: Reassemble the desk lamp

Rearrange everything back in their position and ensure they properly fit together. Then use screwdrivers to securely tighten all the connections.

Step 7: Test the desk lamp

To ensure LED bulbs still work well after the surgery, repower the desk lamp and turn it on to test the new bulb. If the lamp doesn’t work stable, recheck the connection.

If your fixtures have dimmer switches, you also need to test the dimmer to verify that the new LED bulbs are compatible and work well with the dimmer. 

Wait! Wait! You have already completed the process successfully, but don’t forget to dispose of the old bulbs properly as electronic components inside bulbs may harm the environment. Many municipalities have recycling programs for old bulbs. Check with your local waste disposal facility for guidance.

7 Common Problems When Replacing LED bulbs in Desk Lamps

Although this is a simple task, there are some potential problems that may occur and their solutions:

• Overheating: Although LED lamps commonly don’t generate excessive heat, they may overheat sometimes since the bulb is too close to insulation or if the fixture does not allow air circulation. It will help if you change to a smaller LED bulb.
• Compatibility issues: Using bulbs incompatible with the lighting fixtures or dimmer switches leads to incorrect brightness levels (intense brightness or dimming) buzzing, and humming noise. The solution is to carefully read the specifications of the lamp and LED bulbs, and ensure that they are compatible. If you are not confident with your choice, take the old bulb with you to the store or message the shop owner. Don’t be shy or overconfident or it will cost you some pennies for a lesson.
• Color rendering issues: Low-CRI LEDs may affect concentration and eye health. You're aiming for a specific level of brightness for focused tasks and the CRI close to Daylight from the sun (CRI = 100) shows natural and realistic illumination. So desk lamps should have CRI > 80 to be good. However, this issue is about personal preference. Maybe your eyes find oversaturated colors more natural. Whatever, ensure you keep the CRI high.
• Wrong power supply: Incorrect voltage can damage the LED bulb, cause short circuits leading to lamp turn on by itself, produce high heat emission, and damage internal components. Moreover, a higher input voltage can cause high lumen output, or too white illumination, and may be annoying sometimes. Solutions are to get a bulb replacement or to install dimmer switches to tone down the light output (in case the lighting is too disturbing).
• Loose connections: This can cause the bulb to flicker or not work at all. Gently unscrew and securely tighten the connection again. 
• Cracked or broken bulbs: LED bulbs can crack or break during replacement, leading to potential hazards and difficulty in getting the bulb out. Remember to be gentle when touching and replacing the lamp. use duct tape or a piece of potato to create a handhold and then easily remove it from the socket.
• Injury during replacement: There’s a risk of harming yourself while changing LED bulbs, especially if the bulb is hot or if you use excessive force. Keep in mind these safety precautions: make sure you turn off the power (maybe use tape to fix the power button to prevent accidentally flipping on while working); work in a well-lit area; let the bulb cool off before touching; and put on personal protective equipment (if necessary).

Final Thought

Overall, replacing LED bulbs in desk lamps is a straightforward task. Hope this “How to replace LED bulb in desk lamp” can encourage and urge you to choose LED light bulbs today for an energy-efficient, cost-effective lighting solution, and contributing to a more sustainable environment.

FAQs
