How to Conduct LED Aging Tests — A Practical Guide

While aging tests may seem simple, the effectiveness lies in the execution. Here’s how we carry out aging tests in real production and pre-shipment stages.

Equipment & Environment

Aging racks or conveyor lines

Adjustable AC power supply (for voltage fluctuation simulation)

Ambient temperature control (optional)

Time tracking and monitoring system

Testing Procedure

1: Mount the LED lamps securely on the aging rack.

2: Power them on under rated voltage. Common test durations:

Table/Floor Lamps: ≥ 2 hours

Ceiling/Downlights: ≥ 4 hours

3: Observe during operation:

Is brightness stable?

Any flickering, dead LEDs, or color shift?

Abnormal heat, noise, or odor?

4:  Recheck the lamps after aging to ensure no deformation or functional faults.

Common Issues & Fixes

Issue Possible Cause Suggested Action
Flickering Poor driver quality Replace with better drivers
Partial outage Faulty soldering/LEDs Rework or replace LED beads
Odor/discoloration Inadequate heat design Improve thermal structure
