This ballast bypass LED grow lamp (40W Eqv.) works with existing T8 fluorescent light fixtures by bypassing the ballast and wiring the lamp holders (tombstones) to a single end. Without the need for a ballast, these universal voltage 120-277V lamps do not flicker, buzz or experience longevity issues.*Requires bypassing the ballast during installation. Requires non-shunted lamp holders (tombstones). Please refer to the T8/T12 LED GROW LIGHT BYPASS BALLAST INSTRUCTIONS VIDEO below for detailed installation steps.
