1. Check the packaging: When buying spotlights, check the packaging for information such as the manufacturer's location, contact information, and product wattage. If these details are missing, it indicates a product from a non-reputable manufacturer, with no quality guarantee and no after-sales service.
2. Examine the spotlight's appearance: The spotlight's surface should be smooth and clean, without scratches or burrs. Touch the surface; it shouldn't feel rough. Shake the light to listen for any internal sounds and check for any foreign objects inside, as these could cause short circuits and damage.
3. Spotlights come in high-voltage and low-voltage types. Low-voltage spotlights have a longer lifespan and higher luminous efficacy. Higher wattage generally results in better luminous efficacy. Ordinary spotlights have a wattage of around 0.5 watts. While high-voltage spotlights offer better brightness, they consume more electricity. Choose according to your individual needs.
4. Check the color of the light. When buying spotlights, most people buy three, five, or even more than one. Therefore, observe whether the light color is consistent. If there are obvious differences, it indicates that the quality of the light is not guaranteed.
5. Check the heat dissipation of the spotlight. When purchasing, ask the seller to turn on the light fixture for more than 30 minutes, then touch the heat sink to see if it gets too hot. If it feels hot to the touch, it means that its internal heat dissipation is poor.
