Is it possible my new bulb is defective? Yes, it’s possible that your new bulb is defective. If your bulb doesn’t light up when installed, flickers intermittently, or burns out quickly, these could be signs of a defect. Checking the bulb’s compatibility with your fixture and ensuring proper installation can help determine if the bulb itself is the issue.
How to Identify a Defective Bulb
New light bulbs can sometimes be defective due to manufacturing errors or damage during shipping. Here are some common signs that your bulb might be defective:
- Doesn’t light up: If the bulb doesn’t illuminate when switched on, it could be defective. Ensure the fixture is powered and the bulb is properly screwed in.
- Flickering: A bulb that flickers or dims intermittently might have a loose filament or internal wiring issue.
- Burns out quickly: If your bulb burns out much sooner than its expected lifespan, it could be due to a defect.
