Product Overview
This SubstiTUBE T5HE lamp provides an energy-saving LED alternative to standard-output fluorescent T5 lamps while retaining operation on select compatible programmed rapid start electronic T5 ballasts. It is instant-on, mercury-free, has no lamp polarity, and uses frosted glass optics for uniform light distribution.
The lamp is intended for Type A retrofit applications where the existing ballast remains in place. Ballast compatibility must be confirmed before installation, and the product cannot be used with High Output ballasts.
Compatible Applications
- Commercial and institutional T5 fluorescent retrofit applications
- Fixtures using compatible programmed rapid start electronic T5 ballasts
- Dry and damp indoor locations
- Occupancy and vacancy sensor applications when the ballast/system is compatible
