LED Tube Lights Buying Guide

What are LED Tube Lights? LED tube lights have rapidly gained popularity as a preferred lighting solution. They provide bright, uniform illumination over expansive areas. A contemporary LED tube light outshines many alternatives in terms of brightness, energy efficiency, minimal maintenance, and longevity.

The extensive coverage and energy efficiency of LED tube lights make them an ideal choice for various settings, including workshops, garages, warehouses, construction sites, parking lots, kitchens, hallways, and entryways, among others.

With a multitude of LED tube lights available, identifying the best type for your specific needs is crucial before making a purchase. Below, you'll find a brief guide to help you determine which LED tube light will suit your requirements best.

How to Choose an LED Tube Light

Several factors play a role in selecting the right tube light. Even though LED tube lights present numerous advantages, their effectiveness can vary based on specific scenarios. It is essential to understand that LED tube lights are different from fluorescent, incandescent, or halogen lights. Below are key parameters to consider when choosing your LED tube light:

Overall Cost

While the initial purchase price of LED tube lights may be higher than other types, their long-term costs are significantly lower due to their durability, low maintenance needs, and superior energy efficiency.

Lighting Color Temperatures

LED lights typically range from 2700K to 6500K, creating uniform lighting across their span. Assess the type of lighting required in your space before choosing the LED tube:

  • 5000K will produce a bright, clinical blue light, well-suited for hospitals, art studios, offices, and warehouses.

  • 4000K offers a vibrant light with reduced glare, suitable for offices, supermarkets, garages, and showrooms.

  • 3000K provides a warm ambiance with red and orange hues, perfect for homes, restaurants, and hotels.

Lumens vs. Watts

LED brightness is measured in lumens rather than watts. Lumens indicate the total light emitted by the bulb, whereas watts measure energy consumption. It's beneficial to determine your desired lumen output. A rough guide is as follows:

  • 40W = 450 lumens
  • 60W = 800 lumens
  • 75W = 1100 lumens
  • 100W = 1600 lumens
  • 150W = 2600 lumens

LEDs and Dimming

The relationship between energy sent to an LED and its brightness is not as straightforward as it is with other bulbs. To dim LED lights, you must find tube lights compatible with dimmers or install an LED-compatible dimmer switch.

Difference Between T5, T8, and T12 LED Tubes

LED tube lights come in three common sizes, identified by a 'T' measurement. The 'T' corresponds to 1/8th of an inch. Generally, higher 'T' ratings indicate thicker tube diameters:

  • T5 = 5/8 inches
  • T8 = 1 inch
  • T12 = 1.5 inches

It's essential to note that a smaller diameter does not guarantee better energy efficiency. For instance, while T5 tubes consume less energy than T8s, T12s can operate at nearly half the energy of T5s.

Types of LED Tubes

Four main types of LED tubes are currently on the market. While they all provide LED lighting, they differ in installation and circuitry. Understanding these differences is crucial:

  • Type A: LED tube with integrated driver. Operates on the existing fluorescent ballast and is compatible with T12, T8, and T5 ballasts, making it user-friendly.
  • Type B: Ballast bypass LED tube that connects directly to mains voltage. This type simplifies installation by avoiding ballast-related issues.
  • Type C: Features an external driver instead of an integrated one. It offers superior performance but requires electrical modifications to the current fixture.
  • Type A+B: Dual mode internal driver, allowing operation off the existing ballast or through line voltage if rewired.

Installing LED Tube Lights

Prioritizing safety is essential when installing any lighting. LED tubes are efficient and can often replace existing fluorescent fittings:

  1. Disconnect the fixture from the power supply.
  2. Carefully remove the old tube.
  3. Check and remove the ballast if necessary.
  4. Install the new LED tube by connecting the live and neutral wires correctly.
  5. Reconnect the power and test the fixture.
  6. Dispose of old tubes properly, considering the environmental impact of fluorescent lights.

FAQs

What differentiates an LED batten from an LED tube light?

An LED batten emits light in a half-sphere shape, while an LED tube provides full-sphere illumination, generally with better energy efficiency.

What is the lifespan of LED tube lights?

LED tube lights typically last around 50,000 hours, which equates to about 16 years.

Can I mix LED and fluorescent tubes?

While replacing fluorescent tubes with LED ones is feasible, it is advisable not to mix them within the same circuit, as it can lead to flickering.

Which LED tube light offers the brightest output?

Typically, a 6000K LED tube light will provide the brightest illumination.

Understanding LED Tube Light Types and Wiring

Wiring Methods and Compatibility

Fluorescent fixtures are more complex than standard residential lamp fixtures due to their use of a fluorescent ballast to regulate electrical current. In contrast, LED technology operates without the need for an external ballast.

However, some LED tube lights are designed to be backwards-compatible with existing fluorescent ballasts, while others work only with certain ballast types. Others, such as those using Waveform Lighting's TriplePlay technology, can adapt to all wiring configurations.

When selecting an LED tube light, it is critical to review its wiring specifications to ensure compatibility with your fluorescent fixture.

Here are the possible wiring methods for LED tubes:

Ballast-Compatible: In this configuration, the fluorescent ballast remains connected, allowing for simple installation without rewiring. This is often referred to as UL Type A or "plug and play."

Direct-Wire, Single Ended: This wiring method connects line voltage directly to the LED tube. Live and neutral wires are fed to one end, leaving the other end unconnected. This setup is also known as UL Type B.

Direct-Wire, Double Ended: These lamps require live and neutral wires connected to opposite ends. This configuration can allow for power delivery to both ends depending on the type of lampholder used.
