How To Replace A Medical Halogen Lamp Safely

Before Replacing Your Lamp

Always:

✓ Switch equipment off
✓ Allow the lamp to cool
✓ Confirm the replacement specification
✓ Follow equipment instructions

Step 1: Switch Off Equipment

Turn off the equipment completely before removing the lamp.

Halogen lamps operate at high temperatures, so allow sufficient cooling time.

Step 2: Remove The Old Lamp

Carefully remove the existing lamp.

Avoid forcing the connection or damaging the lamp holder.

Step 3: Handle The New Lamp Carefully

Avoid touching the glass with bare fingers.

Skin oils can create hot spots and may reduce lamp life.

Use:

• Clean gloves
• Tissue
• Clean cloth

Step 4: Install The Replacement Lamp

Check:

✓ Correct position
✓ Secure connection
✓ Correct fitting

Do not force the lamp into place.

Step 5: Test The Equipment

After replacement, check:

• Light output
• Stability
• Correct operation

Signs Your Lamp Needs Replacing

Look for:

Reduced Brightness

The lamp may still work but produce less light.

Colour Change

Older lamps may produce inconsistent colour.

Flickering

This may indicate the lamp is reaching the end of its life.

Complete Failure

Keeping the correct replacement available can reduce downtime.

Common Mistakes To Avoid

Avoid:

❌ Buying only by appearance
❌ Using incorrect voltage
❌ Using incorrect wattage
❌ Touching lamp glass
