Why do LED lights gradually become dimmer over time?

Over time, the LED chip ages, leading to a reduction in luminous flux. Insufficient heat dissipation or aging drivers can also cause brightness to decrease.

Do LED lights harm eyesight?

High-quality LED lights do not harm eyesight. However, poor-quality lights may cause flickering or excessive blue light, so it’s recommended to choose products that meet national standards.

Can LED lights be used outdoors?

For outdoor use, choose LED lights with a high waterproof rating (such as IP65 or higher) to ensure they can withstand rain and dust.

Why do some LED lights make a buzzing sound?

This is usually caused by electromagnetic interference in the driver or an incompatible dimmer. Replacing the driver or using a compatible dimmer can resolve the issue.

Can LED lights be dimmed?

Many LED lights support dimming, but they require a compatible dimmer. Using an incompatible dimmer may cause flickering or damage the light.

What is the Color Rendering Index (CRI) of an LED light?

The CRI measures how accurately a light source reveals the true colors of objects. LED lights typically have a CRI of 80-90, with high-quality LEDs reaching 95 or above.

Do LED lights generate heat?

LED lights produce much less heat compared to traditional bulbs. The small amount of heat generated is usually dissipated through aluminum heat sinks or cooling fins to maintain stable operation.

Why do LED lights sometimes flicker?

This could be due to unstable power supply voltage, a faulty driver, or poor-quality LED lights. Check the wiring and consider replacing the driver or the light.

What is the lifespan of an LED light?

High-quality LED lights typically last between 25,000 and 50,000 hours, much longer than traditional bulbs. However, the exact lifespan depends on usage conditions and frequency.

Why are LED lights more energy-efficient than traditional bulbs?

LED lights use light-emitting diodes (LEDs) as their light source, directly converting electrical energy into light energy, which reduces heat loss and improves energy efficiency.
