Detailed Specifications

Usage and Installation Guide

Installing an E12 LED bulb is a straightforward process, but a few key points can ensure optimal performance and safety.

1. Safety First: Always turn off the power to the light fixture at the circuit breaker before installing or replacing a bulb.
2. Check Compatibility: Ensure your fixture is rated for the bulb's wattage and voltage. While 4W is low, confirming compatibility with older fixtures is wise.
3. Handling: Hold the bulb by its base, not the glass globe, to prevent fingerprints or potential damage from skin oils.
4. Installation: Align the bulb's E12 screw base with the socket and gently twist it clockwise until it is snug. Do not overtighten.
5. Dimmer Compatibility: This specific model is non-dimmable. Using it with a dimmer switch may cause flickering, buzzing, or premature failure. For dimmable circuits, ensure you purchase a bulb specifically labeled as "dimmable."
6. Operating Environment: The specified working temperature is -25°C to 45°C. It is designed for indoor use in dry locations unless specified as damp or wet rated.

Buying Guide and Tips

When purchasing E12 LED bulbs, consider the following factors to get the right product for your needs:

• Base Type (E12 vs. E26/E27): E12 is the smaller candelabra base. E26/E27 is the standard medium base. Double-check your fixture's socket size before buying.
• Brightness (Lumens): A 4W LED bulb like this one typically produces around 350 lumens, which is roughly equivalent to a 25-30W incandescent bulb. For brighter needs, look for higher wattage (e.g., 6W, 9W) or higher lumen output.
• Color Temperature:                    
  • 2700K (Warm White): Creates a cozy, relaxing atmosphere ideal for living rooms and bedrooms.
  • 4000K (Natural White): Provides a clean, neutral light perfect for kitchens, offices, and workspaces.
  • 6000K (Cool White): Emits a bright, bluish-white light suitable for garages and task lighting.
• Shape and Style: G45 is a common globe shape. Other popular shapes for E12 bases include B11 (candle), C7 (nightlight), and ST64 (Edison-style).
• Wholesale Purchasing: On platforms like 6688789, minimum order quantities (MOQ) often apply, such as 200 pieces. This is ideal for businesses, contractors, or large renovation projects.
