LED Replacement for “Metric” Fluorescent Lamps
This LED tube is designed to replace the unique “Metric” fluorescent lamps found only in Canada. Oddly named “Metric,” these lamps measure 1160 millimetres in length—not quite the round, base-10 number you’d expect from a metric system standard like a kilometre (1000 metres) or a metre (100 centimetres). Why the unusual size? It’s anyone’s guess—perhaps a clever marketing move from the 1970s to make these custom lamps stand out. Whatever the reason, thousands of these fixtures were installed across Canada, leaving many stuck with this quirky standard.
The good news? We’ve got an affordable LED solution that not only fits but outperforms. This 1160 mm LED tube is ballast-compatible, working with T8 electronic fluorescent ballasts. (Note: If your system uses a T12 “Metric” ballast, you’ll need to upgrade the ballast too—we’ve got those available.) It saves 40–70% on energy compared to traditional fluorescent lamps and lasts 2–3 times longer, making it a smart, cost-effective upgrade.
At 3500 Kelvin, this tube delivers balanced light—slightly whiter than Warm White but not as stark as Cool White. It’s a versatile choice, often used to replace Warm White versions, offering energy-efficient performance and long-lasting comfort. Swap out your outdated “Metric” lighting with this high-efficiency LED option today.
