High-output areas like kitchens or workspaces may require modules with 2000+ lumens. Always match the lumen output to your space size and intended use—under-lighting creates strain, while over-lighting can be harsh and wasteful.

2. Color Temperature (CCT – Correlated Color Temperature)

   Color temperature, measured in Kelvin (K), determines the "warmth" or "coolness" of the light. For residential settings:

   • 2700K–3000K: Warm white – ideal for bedrooms, living rooms, and dining areas, creating a cozy, inviting atmosphere.
   • 4000K–4500K: Neutral white – suitable for kitchens, bathrooms, and offices, offering balanced visibility.
   • 5000K–6500K: Cool white/daylight – best for garages, workshops, or retail spaces where alertness and clarity are needed.

   Avoid overly cool temperatures in relaxation areas, as they can feel sterile or disruptive to circadian rhythms.

3. Energy Efficiency (Lumens per Watt)

   Efficiency is calculated as lumens per watt (lm/W). Higher values mean more light for less electricity. Modern 220V AC LED modules should offer at least 100–130 lm/W. Premium modules can exceed 150 lm/W, significantly reducing long-term energy costs. Compare efficiency ratings when selecting between models to maximize savings, especially in high-usage environments.

4. Lifespan and Longevity

   Most quality LED modules last between 25,000 and 50,000 hours. Look for modules labeled with an L70 or L80 rating, which indicates how long it takes for brightness to drop to 70% or 80% of the original output. A longer lifespan reduces maintenance frequency and replacement costs—critical in hard-to-reach installations like ceiling coves or outdoor fixtures.

5. Dimmability and Control Compatibility

   Not all 220V AC LED modules are dimmable. If adjustable lighting is desired, ensure the module explicitly states "dimmable" and check compatibility with your dimmer switch (e.g., leading-edge, trailing-edge, or smart dimmers). Non-dimmable LEDs used with dimmers may flicker, buzz, or fail prematurely. For smart lighting integration, consider modules compatible with systems like Zigbee, Z-Wave, or Wi-Fi-enabled drivers.

6. Heat Dissipation and Thermal Management

   While LEDs produce less heat than traditional bulbs, poor thermal design can still lead to overheating, reducing efficiency and lifespan. Look for modules with aluminum substrates or heat sinks that effectively dissipate heat. Avoid enclosed fixtures unless the module is rated for such use. Modules with thermal protection features offer added reliability in high-temperature environments.

7. Build Quality and Materials

   Durable construction is vital for longevity. High-quality 220V AC LED modules typically use:
