Linear LED's TLED Tubes

LED Tubes (TLEDs) – A Comprehensive Guide to Retrofitting Fluorescent Fixtures

LED Tubes, commonly referred to as TLEDs, are designed to replace traditional linear fluorescent lamps while utilizing existing fixtures and sockets. These energy-efficient solutions offer facility managers a cost-effective way to upgrade their lighting systems without the need for a complete overhaul. In this guide, we’ll explore the different types of TLEDs, their advantages and disadvantages, and key considerations for retrofitting fluorescent fixtures.

What Are LED Tubes (TLEDs)?

LED Tubes are designed to match the form factor of linear fluorescent lamps, making them a direct replacement option. They come in the same lengths and pin configurations as fluorescent tubes, allowing them to fit seamlessly into existing fixtures. However, the wiring and auxiliary equipment required may vary depending on the type of TLED solution chosen.

Retrofitting fluorescent fixtures with TLEDs offers several benefits, including energy savings, reduced maintenance costs, and improved lighting quality. However, with multiple TLED options available, it’s essential to understand the differences to make an informed decision.

Types of TLED Retrofits

There are four main types of TLED retrofits, each with unique features and installation requirements:

1. UL Type A: Ballast-Compatible TLEDs

How It Works: Type A TLEDs use the existing fluorescent ballast and feature an internal driver for compatibility.

Advantages:

• Lowest installation cost
• Plug-and-play installation
• Easy to upgrade to Type C with an external driver

Disadvantages:

• Ballast compatibility issues may affect performance
• Potential for flickering, humming, or buzzing
• Lower system efficiency due to energy losses in the ballast
• Limited dimming and controllability

Best For: Facilities looking for a quick, low-cost retrofit solution.

2. UL Type B: Direct-Wire TLEDs

How It Works: Type B TLEDs bypass the existing ballast and are wired directly to the mains voltage. They also include an internal driver.

Advantages:

• Eliminates ballast compatibility concerns
• Higher system efficiency
• Reduces ballast failure and replacement costs

Disadvantages:

• Higher installation cost due to rewiring
• Safety risks associated with high-voltage rewiring
• Limited dimming capabilities
• Potential for flickering in some models

Best For: Facilities seeking long-term energy savings and willing to invest in rewiring.

3. UL Type C: External Driver TLEDs

How It Works: Type C TLEDs use an external driver to power the lamps, bypassing the existing ballast.

Advantages:

• Highest efficiency and performance
• Compatible with dimming and advanced lighting controls
• Longer lifespan compared to other TLED types

Disadvantages:

• Higher upfront cost
• Requires professional installation
• Limited compatibility across manufacturers

Best For: Facilities prioritizing advanced lighting controls and long-term performance.

4. Hybrid Type A/B: Dual-Mode TLEDs

How It Works: These TLEDs can operate as Type A (using the existing ballast) or Type B (direct-wire) after ballast failure.

Advantages:

• Flexibility in installation
• Cost-effective transition from ballast to direct-wire operation

Disadvantages:

• Slightly higher initial cost than Type A
• Requires rewiring for Type B operation

Best For: Facilities seeking a versatile solution that adapts to future needs.

Key Considerations for TLED Retrofits

When choosing a TLED retrofit solution, consider the following factors:

1. Efficiency

Type A TLEDs are less efficient due to energy losses in the ballast. Type B and Type C TLEDs offer higher system efficiency by eliminating the ballast.

2. Optical Quality

TLEDs often have different light distribution patterns compared to fluorescent lamps. Ensure the chosen TLED provides even light distribution to avoid uneven illumination.

3. Product Lifetime

The lifespan of Type A TLEDs depends on the existing ballast. If the ballast fails, maintenance costs may increase. Type B and Type C TLEDs offer longer lifespans and reduced maintenance.

4. Safety

Type B TLEDs require rewiring, which can pose safety risks if not done correctly. Always follow UL guidelines and use warning labels.

5. Cost

Type A TLEDs have the lowest upfront cost but may incur higher long-term maintenance expenses. Type C TLEDs have a higher initial cost but offer greater energy savings and performance.

Conclusion

Retrofitting fluorescent fixtures with LED Tubes (TLEDs) is a smart way to achieve energy savings and improve lighting quality. However, the right solution depends on your facility’s specific needs, budget, and long-term goals. Whether you choose Type A, Type B, Type C, or a hybrid solution, understanding the tradeoffs is crucial for making an informed decision.

For the best results, consult with a lighting professional to evaluate your existing fixtures and determine the most suitable TLED retrofit option. By upgrading to LED Tubes, you can enjoy significant energy savings, reduced maintenance costs, and a brighter, more efficient workspace.
