  • Light output: E4 LED lights are bright and offer high lumen output. Depending on the type, the lumen output can range from 200 to 1000 lumens. This makes them ideal for various applications, including reading, commercial lighting, and residential lighting.
  • Color temperature: The E4 LED light bulbs are available in different color temperatures. This offers options for different applications. Depending on the type, the color temperature can range from 2700K to 6000K. The 2700K offers a warm white light, while the 6000K has a cool daylight tone.
  • Beam angle: E4 LED light bulbs have different beam angles. Depending on the type, the beam angle can range from 30° to 120°. This makes the lights suitable for various applications, such as spotlighting, wall washing, and general lighting.
  • Color rendering index: The E4 LED lights have a good color rendering index. Depending on the type, the CRI can range from 80 to 95. This means that the bulbs offer accurate color representation, making them ideal for applications that require precise color rendering, such as art studios and retail.
  • Dimmability: Some E4 LED light bulbs are dimmable, while others are not. The dimmable ones allow users to adjust the brightness according to their needs. This feature is energy efficient and creates a suitable ambiance.
  • Lifespan: 12V E4 LED light bulbs have a long lifespan. Depending on the type, the lifespan can be up to 50,000 hours. This reduces maintenance costs and the need for frequent replacements.
  • Material: The E4 LED lights are made of high-quality materials. Depending on the type, they can be made of aluminum, glass, and plastic. This ensures durability and excellent performance.
  • Dimensions: The size and shape of the E4 LED lights vary depending on the type and manufacturer. The LED E4 light bulbs have a standard E4 base with a diameter of about 4mm. The length varies depending on the type and can range from 10mm to 20mm.

Maintaining 12V LED E4 lights is essential to ensure they last long and function well. Here are some of the maintenance requirements:

  • Regular cleaning: Dust and dirt can affect the light output of the LEDs. It's important to clean the lights regularly to ensure they are dust-free. A soft cloth or brush will do the work.
  • Check for loose connections: Loose connections can cause flickering or complete failure of the LED lights. Regularly check all the connections to ensure they are tight.
  • Replace damaged lights: If any of the E4 LED lights are damaged, replace them as soon as possible. This will prevent strain on the remaining lights and ensure even lighting in the area.
  • Inspect for moisture damage: Moisture can damage LED lights, especially if they are not moisture-proof. Check the lights for any signs of moisture damage. If there are any, replace the affected lights.
  • Check the power supply: The E4 LEDs require a stable 12V power supply. Fluctuations or over-voltage can damage the lights. Regularly check the power supply to ensure it is functioning well.

How to choose 12V LED E4

Wholesale buyers need to consider various factors when choosing the right LED E4 for their market. Here are some of them:

  • Consider the Purpose of the Bulb

    Different E4 bulbs have different color temperatures. They range from 2700K to 6500K. The E4 bulbs with warm colors (2700K to 3000K) are ideal for homes and restaurants. The ones with cool colors (4000K to 4500K) are suitable for offices, while the daylight colors (5000K to 6500K) are ideal for retail.

  • Brightness

    Bright lights are crucial in places with low visibility or in areas where activities that require great attention are carried out, such as in hospitals. E4 bulbs have different lumen outputs, so wholesalers should choose the ones that suit their market needs.

  • Energy Efficiency

    Most E4 bulbs are energy efficient. They help reduce energy costs. They are also durable, which helps reduce the cost of replacement. However, the energy efficiency and durability of the bulbs may differ depending on the brand. Therefore, wholesalers should choose bulbs from brands that are known for superior energy efficiency and durability.

  • Color Rendering Index (CRI)

    Wholesalers should consider the Color Rendering Index (CRI) of the bulbs. They should choose bulbs with a high CRI (above 80) if they want accurate color representation. The bulbs with a low CRI (below 80) are suitable for places where precise color representation is not that important.

  • Quality of Light

    Quality of light entails factors like flicker, stability, and uniformity. Wholesalers should choose bulbs that emit stable, flicker-free light with uniform brightness to ensure comfort and safety in various settings.

  • Design and Aesthetics

    Wholesalers should choose bulbs that suit their customers' preferences. The bulbs have different designs, sizes, and finishes.

  • Compatibility

    Wholesalers should ensure that the bulbs are compatible with the existing fixtures and lighting systems. They should choose bulbs with the right base types and wattage equivalents to ensure seamless integration.

  • Cost

    Cost is an important factor when choosing the E4 bulbs. Wholesalers should compare the value of different E4 bulbs from various suppliers and brands and choose the ones that give them the best value for their money.
