Find the Best T8 LED Tube
What Does "T8" Really Mean?
The label "T8" might sound technical, but it’s actually pretty straightforward. The "T" refers to the tube's shape – tubular – and the "8" means it's 8 eighths of an inch in diameter. That’s just a fancy way of saying it's 1 inch wide. Almost all standard fluorescent fixtures in local homes, garages or warehouses use these T8 tubes with a G13 b-p base – two pins spaced 13mm apart. This makes T8 LED tubes a plug-and-play option, provided you check the ballast compatibility first.
Can T8 LED Tubes Fit in Existing Fluorescent Fixtures?
In most South African homes and commercial buildings, the answer is yes. T8 LED tubes are designed to work inside the same fittings as their fluorescent cousins. However, before you pop them in, double-check the type of ballast in place – or if you even need it.
“I upgraded our kitchen lights using direct wire T8 LEDs and removed the old ballast. No more flickering during loadshedding!”
Understanding the Wiring Types
Type A – Plug & Play
These work with compatible electronic ballasts. No rewiring needed. Quick, but the ballast can still fail.
Type B – Direct Wire
Ballast is removed completely. Wire direct to mains. Safe, long lifespan, but requires installation know-how (or a licensed electrician).
Type C – External Driver
Less common in homes. Uses an external driver like low-voltage strips. More control, often commercial use.
How to Install a Double-Ended Tube (Safely)
A double-ended T8 LED tube connects live (hot) on one end and neutral on the opposite. This keeps the current flow safe and clean.
“If you're upgrading a garage or office, definitely double-check if your tubes are single or double-ended. It affects how you wire the tombstones.”
