Do you have to remove the ballast when installing the EverLED TR?

No. Unlike other LED replacements for linear fluorescent tubes, the EverLED TR LED Tube Light is the worlds first ballast compatible LED product. The EverLED-TR is designed to function with both T8 and T12 standard electronic and magnetic ballasts.  This unique feature makes the EverLED-TR a true “drop-in” solution and saves the considerable expense of hiring electricians to rewire the fixture and remove the existing ballast.
