LED Corn Bulb 5730 SMD 45W Equivalent Bright Light - E27 E14 B22 Guide | OEM RD1790-blast

Applications

This 45W LED corn bulb is designed for high-brightness general lighting purposes. Its 360-degree beam angle makes it ideal for illuminating large areas such as:

• Home Lighting: Living rooms, bedrooms, and basements.
• Commercial Lighting: Warehouses, workshops, retail stores, and garages.
• Industrial Lighting: Factories and production floors where wide-area coverage is needed.

Installation Steps

1. Safety First: Ensure the power is completely turned off at the circuit breaker before installation.
2. Check Compatibility: Verify that your lamp holder matches one of the bulb's base types (e.g., E27, B22). E27 has a 27mm diameter screw, while E14 is smaller at 14mm .
3. Screw In: Align the bulb's base with the lamp holder and gently screw it in clockwise until it is secure. Do not overtighten.
4. Power On: Restore power and test the bulb.

Key Considerations

• Power vs. Brightness: 45W is equivalent to a high-wattage traditional bulb. For a 30 sqm room with a 2.8-3m ceiling, a 23W bulb is usually sufficient, so 45W provides ample illumination for larger spaces .
• Color Temperature: Choose based on the ambiance you want to create. Warm white (2700-3000K) is cozy for bedrooms, while cool white (5000-6500K) is better for task lighting in kitchens or workshops .
• Brand vs. Price: OEM products like this often offer competitive pricing. Compare with established brands like Philips or OSRAM for features like smart connectivity or higher CRI, which may come at a premium .
• Certification: Ensure the product has relevant safety certifications (like CE, RoHS) for your region to guarantee quality and safety .

Price Range

On platforms like 6688789, wholesale prices for similar E27 corn bulbs can vary widely. Basic models can start as low as $0.46-$0.48 per piece for large orders (MOQ: 100 pieces), while higher-specification or branded units can cost several dollars each .

Technology Deep Dive: SMD5730

The SMD5730 chip is a key component. It's a 5.7mm x 3.0mm LED known for its efficiency and brightness, typically operating at 150mA with a power range of 0.3W to 0.5W per chip . A bulb using 5730 chips can achieve high luminous efficacy, often around 100 lm/W, meaning it produces more light per watt of energy consumed .

Performance Metrics

• Luminous Flux: While the exact lumens for this specific model aren't provided, a typical 60W equivalent LED corn bulb using 160x5730 SMDs can produce around 5850 lumens .
• Energy Efficiency: LED technology is far more efficient than incandescent or CFL bulbs, leading to significant energy savings over its 50,000-hour lifespan .
• Heat Dissipation: The corn cob design with multiple LED chips allows for better heat distribution compared to single-point LEDs, which helps in maintaining light output and longevity .

Warranty and Returns

This product comes with a 3-year warranty. When purchasing from platforms like 6688789, it's crucial to understand the supplier's return policy. Under 6688789's Trade Assurance, buyers can pay securely, and funds are released only after confirming product quality. If issues arise, a dispute resolution process is available .

Consumer Rights

If you receive a product with quality problems, you have legal rights. In many jurisdictions, you can request a return, replacement, or repair within a specified period. In China, for example, consumers can often return goods within seven days of receipt if they don't meet quality standards .

Troubleshooting Common Issues

• Bulb doesn't light up: Check the power supply and ensure the bulb is screwed in properly. Test with another socket if possible.
• Flickering: This could be due to an incompatible dimmer switch (this model does not support dimming) or a loose connection .
• Overheating: While some heat is normal, excessive heat could indicate a problem with the bulb's internal driver or poor ventilation. Discontinue use if overheating occurs .

Q1: What is the difference between E27 and E14 bases?

A: E27 (27mm diameter) is a standard "large" screw base, while E14 (14mm diameter) is a "small" screw base. They are not interchangeable and are used in different types of fixtures .

Q2: Is this bulb suitable for outdoor use?

A: The specifications do not list an IP (Ingress Protection) rating. Without a rating like IP65 (which indicates dust-tight and protection against water jets), it is not recommended for outdoor use where it would be exposed to the elements .

Q3: Can I use this bulb in an enclosed fixture?

A: The working temperature is listed as -20°C to 60°C. Using it in a fully enclosed fixture may cause it to exceed this temperature range, potentially shortening its lifespan. It's best used in open or well-ventilated fixtures.

Q4: What does "corn bulb" mean?

A: The name comes from its appearance, which resembles a corn cob. It has multiple LED chips arranged on a cylindrical structure, providing 360-degree omnidirectional lighting .
