How to Replace Flash Lamps in Aesthetic Laser Machines — Step-By-Step Guide

Flash lamps are the part inside your laser machine that creates the light used for treatments. After many sessions, they naturally wear out because they keep getting hot, releasing strong energy, and leading to reduced power, slower results, and increased downtime.

If you’re noticing weak pulses, inconsistent shots, or error warnings, it’s time to replace your flash lamp.

Here’s a simple guide on how to change a flash lamp safely, what to avoid, and where you can buy good-quality lamps.

1. When Should You Replace a Flash Lamp?

Most laser machines need a new flash lamp after they fire a few hundred thousand shots.

1.    Visible wear or carbon marks
2.    Drop in fluence or output energy.
3.    Overheating or sudden error codes
4.    Burnt smell or darkening inside the lamp

If your machine feels weak or treatments take longer than usual, the flash lamp is usually the cause.

2. Tools You Need Before Starting

Before changing the lamp, keep the basic tools ready — gloves, screwdrivers, and any parts your machine commonly uses, like O-rings.

Tip: Always use original-spec flash lamps to avoid energy loss and machine damage.

3. Step-By-Step: How to Replace Flash Lamps in Laser Machines

(General procedure — always follow your machine’s manufacturer guidelines.)

Step 1: Turn Off & Cool the Machine

Disconnect power and allow the handpiece to cool thoroughly.

Never open a hot handpiece — it can crack internal components.

Step 2: Open the Handpiece

Open the handpiece slowly. Take your time and be gentle because there are glass parts and mirrors inside that can break easily.

Step 3: Take Out the Old Flash Lamp

Remove the old lamp carefully. Don’t pull or twist too hard.

Try not to touch the shiny or reflective parts inside—they can get damaged or lose performance.

Step 4: Clean the Inside

Wipe the inside area using a soft, clean cloth.

Remove any dust, black marks, or dirt.

If your machine has a quartz tube (flow-tube type), check that it’s clean and not cracked.

Step 5: Install the New Flash Lamp

Place the lamp inside carefully.

Make sure:

o   electrodes face the correct direction

o   The lamp sits in the centre.

o   O-rings or ceramic holders fit properly

Step 6: Reassemble the Handpiece

Secure all screws tightly.

If the screws aren’t tight, the handpiece might shake, damaging the new lamp.

Step 7: Test the Machine

After closing the handpiece, test the machine by firing a few low-energy shots to make sure everything works properly.

Check:

o   energy output

o   cooling

o   sound/consistency of shots

If everything is stable, your machine is ready for treatments.

4. Common Mistakes to Avoid

1.    Touching the lamp with bare hands
2.    Using cheap, low-quality lamps (causes overheating)
3.    Misaligning the lamp inside the cavity
4.    Forgetting to clean reflectors
5.    Operating immediately without a test run
6.    A wrong installation can damage the power supply or trigger fatal error codes.
