Converting Fluorescent Fittings to LED Tubes โ What Must Be Checked
Learn convert fluorescent to LED tube in simple terms. An LED tube conversion is an electrical compatibility job, not simply a lamp swap. This guide includes selection checks, common mistakes and relevant Whitehouse product examples.
Quick answer: An LED tube conversion is an electrical compatibility job, not simply a lamp swap.
Why this matters
Customers often reach a product page after searching for one specification, but the correct result depends on how several specifications work together. Understanding the terms below helps prevent incompatible purchases, poor light quality and unnecessary replacement costs.
- Traditional fluorescent fittings may include magnetic ballasts, electronic ballasts and starters.
- LED tube products differ: some are designed for direct mains connection, some work with selected control gear and some use supplied LED starters.
- Incorrect wiring can create shock, fire or equipment-damage risks.
- Labelling a converted fitting helps future maintenance teams understand the new wiring arrangement.
How to choose the right product
- Identify the existing ballast type.
- Read the LED tube wiring diagram and supply-end marking.
- Inspect lampholders for heat damage or brittleness.
- Have rewiring completed and tested by a qualified electrician.
- Use identical tubes in multi-lamp fittings unless the manufacturer permits mixed arrangements.

That depends on the LED tube design. Some products use an LED starter or require rewiring; follow the product instructions.
Can electronic ballasts run LED tubes?
Only specific compatible combinations. Do not assume universal compatibility.
Why label a converted fitting?
It reduces the chance that a future replacement lamp is installed against the wrong wiring arrangement.
