Round LED Module Q & A: Your Complete Guide

Q1: Can you connect multiple round LED modules together?

Yes, multiple round LED modules can be connected either in series or parallel, depending on your power supply, voltage requirements, and desired brightness output. However, it's crucial to understand the electrical implications of each configuration to ensure safe and efficient operation.

• Series Connection: In this setup, the positive terminal of one module is connected to the negative terminal of the next. The total voltage required equals the sum of the individual module voltages (e.g., connecting three 12V modules in series requires a 36V power supply). Current remains the same across all modules. This method is useful when you have a higher-voltage power source but must ensure all modules are identical to prevent uneven brightness or failure.
• Parallel Connection: Here, all positive terminals are connected together, and all negative terminals are joined. The voltage remains constant (e.g., 12V for 12V modules), but the total current draw increases with each added module (e.g., three 0.5A modules draw 1.5A total). This setup is ideal for low-voltage systems and allows consistent brightness across modules, provided your power supply can handle the increased current load.
• Important Considerations: Always check the manufacturer’s specifications for voltage tolerance, polarity, and maximum current. Use appropriate wiring gauge to prevent overheating, and consider incorporating fuses for circuit protection, especially in larger installations.

For complex lighting projects, using a constant-voltage LED driver with sufficient wattage capacity is recommended to maintain stable performance and extend the lifespan of your LED modules.

Q2: Are round LED modules waterproof?

Not all round LED modules are waterproof—water resistance depends on the design and intended application. However, many models are specifically engineered for outdoor or harsh environments and come with a defined IP (Ingress Protection) rating that indicates their level of protection against dust and moisture.

• IP65-Rated Modules: These are dust-tight and protected against low-pressure water jets from any direction. Ideal for outdoor signage, garden lighting, or covered exterior installations where direct rain exposure is limited.
• IP67-Rated Modules: Offer full dust protection and can withstand temporary immersion in water up to 1 meter deep for 30 minutes. Suitable for more demanding applications such as marine lighting, vehicle underglow, or outdoor fixtures exposed to heavy rain or snow.
• Non-Waterproof Modules: Typically used in indoor or dry environments. These lack sealing and can be damaged by moisture, so they should never be used outdoors or in damp locations.

When purchasing, always verify the IP rating in the product specifications. Additionally, ensure that wiring connections are properly insulated using waterproof connectors or silicone sealant to maintain the integrity of the entire system, even if the module itself is rated for moisture resistance.

Q3: What is the typical lifespan of round LED modules?

The lifespan of round LED modules varies based on build quality, operating conditions, and usage patterns. However, high-quality LED modules generally last between 30,000 and 50,000 hours of continuous operation. This longevity makes them a cost-effective and energy-efficient lighting solution compared to traditional bulbs.

This lifespan is typically defined by the point at which the LED’s brightness drops to 70% of its original output—a metric known as L70. Beyond this point, the light may still function but will appear noticeably dimmer.

• Factors Affecting Lifespan:
  • Heat Management: Excessive heat is the primary cause of premature LED degradation. Modules installed in well-ventilated areas or with heat-dissipating substrates (like aluminum PCBs) tend to last longer.
  • Power Supply Quality: Using a stable, regulated power source prevents voltage spikes and ripple current, both of which can shorten LED life.
  • Operating Environment: Exposure to moisture, dust, or extreme temperatures can accelerate wear, especially if the module lacks proper protection.
  • Duty Cycle: LEDs used continuously will reach end-of-life faster than those used intermittently, though they are designed for long-term operation.
• Brand & Manufacturing Quality: Reputable manufacturers use high-grade semiconductors, phosphor coatings, and encapsulation materials that enhance durability and color consistency over time.

To maximize lifespan, follow installation guidelines, avoid overdriving the LEDs, and perform periodic inspections to ensure connections remain secure and cooling is adequate. With proper care, a quality round LED module can provide reliable illumination for years—equivalent to over 5 years of continuous use or more than a decade with typical daily operation.
