How to Choose LED Energy-Saving Lamps
LED lamps are quite technical, and many people aren’t familiar with the details. Here are five simple steps that help you choose a good LED lamp without any special tools.
1. Check the Packaging and Label
Reputable LED manufacturers will clearly mark important information on the packaging, such as the rated voltage range, power rating, and frequency. High-quality products usually have clear, durable labels that don’t fade easily. You can wipe them with a soft, damp cloth to see if the text remains visible. Also, look for the manufacturer’s logo and any relevant certifications, which indicate reliability.
2. Examine the Appearance of the LED Tube
A genuine LED tube should have a consistent shape and size, showing good manufacturing quality. There should be no cracks or loose parts. The casing is typically made from flame-retardant engineering plastic, not ordinary plastic, which can deform or catch fire. The aluminum parts should be bright and of high quality, ideally made from aviation-grade aluminum.
3. Test the Operating Temperature
When the LED lamp is working normally, it should stay cool. If it gets too hot, its lifespan will be significantly reduced. Also, if the lamp flickers rapidly or shows strong fluctuations when turned on, it may have quality issues. After being powered on for a few minutes, the lamp should feel warm, indicating effective heat dissipation. If there's no warmth, it might be using a fiberglass board instead of an aluminum substrate, which doesn't dissipate heat well.
4. Observe the Startup Performance
A good LED lamp should start instantly without any flickering. If it flashes or takes time to stabilize, it could be a sign of poor internal components or a low-quality driver.
5. Weigh the Lamp
Heavier lamps often mean better materials and construction. A lightweight lamp might use cheap components and lower-quality materials, which could affect performance and longevity.
