Description

This ETL-listed LED 4-foot replacement bulb is great for updating outdated inefficient fluorescent tubes. Its advanced hybrid technology allows for use with most existing electronic ballast or direct wiring to line voltage.  Long lifespan translates to fewer bulb changes.

Using Existing Electronic Ballast (Type A):

• Wire output of ballast to both ends of light tube.

Direct Line Voltage Wiring (Type B):

• Bypass existing ballast and wire line voltage wires to a non-shunted lamp holder (e.g. #1919_B).
• Connect labeled “AC ~ Input” end of light tube to above non-shunted lamp holder.
