Q: Can I Replace Fluorescent Tubes With LED Tubes Without Changing the Fixture?

In many cases, yes, but it depends on the type of LED tube and your current fixture. Some LED tubes are 'plug and play' while others require a rewire.

Q: How Do I Know What Size LED Tube I Need?

Measure your existing tube and match the length and wattage. T8 and T5 are the most common sizes.

Q: Are LED Tubes More Energy-Efficient Than Fluorescent Tubes?

Yes, LED tubes use up to 60% less energy compared to fluorescent tubes.

Q: Do I Need an Electrician to Install LED Tubes?

It depends, plug-and-play LEDs usually don't need an electrician, but ballast bypass installations often do.

Q: What Is the Difference Between a T5 and a T8 LED Tube?

T5 LED tubes are thinner, typically used in newer commercial fittings, and offer high efficiency in compact fixtures. T8 LED tubes are slightly larger and are more commonly used in older or retrofit applications.
