What dual mode means
Many LED tubes force you to choose between a plug-and-play model that needs a ballast and a direct wire model that needs rewiring. The T84F20W does both. In the first mode, it runs on a compatible quick start electronic ballast, so replacing an old fluorescent tube can be as simple as a lamp change. In the second mode, it is connected straight to AC with no ballast, the ideal solution when the ballast has failed or when you want to remove it for good.
Choosing the right installation
Before starting, turn off the power and identify the ballast in your fixture. If it is a quick start electronic ballast in good working order, you can simply swap the fluorescent tube for the LED tube. If it is a magnetic ballast, do not use it with this tube: remove it and wire the tube for a direct AC connection instead. The same applies to a defective ballast. Direct-wire conversions should follow the wiring instructions and the Canadian Electrical Code, and a licensed electrician is your best ally for larger jobs.
Why switch to LED
At 20W, this tube is a straightforward way to cut the energy used by your 4 ft fixtures compared with aging fluorescent systems. LED technology turns on instantly, without the warm-up and flicker of worn fluorescent lamps, and it avoids the mercury they contain. By bypassing the ballast, you also remove a component that often fails in older fixtures, which means fewer service calls and less time on a ladder. The T8 format keeps the classic look of your fixtures, so ceilings stay uniform when you convert a building gradually.

Where to use it
Think of the fluorescent fixtures in a basement workshop, a garage, a laundry room or a storage room at home, and of the troffers and strip lights in offices, classrooms, clinics, retail stores and warehouses. Property managers can standardize on a single tube for buildings that mix working ballasts and dead ones, installing it in ballast mode where possible and in direct mode elsewhere. From Montréal to Edmonton, it is a simple step toward modern LED lighting.
