GE UltraStart T5 Watt-Miser Ballast
The GE UltraStart T5 Watt-Miser ballast operates T5 fluorescent lamps in commercial and industrial fixtures. It supports parallel lamp operation so one lamp can continue running if the other reaches end of life. The unit carries UL approval for ambient temperatures up to 55C.
Parallel Operation and Cold-Weather Starting
Parallel lamp wiring reduces maintenance because a single lamp failure does not darken the entire fixture. Fast starting time under 700ms delivers near-instant illumination. A minimum starting temperature of -20F allows reliable operation in unheated warehouses, parking garages and outdoor signage.
Replaces Magnetic or Older Electronic Ballasts
This ballast replaces magnetic or earlier electronic models that lack parallel operation, anti-striation control or cathode cutout technology. The upgrade is worth it when you need lower maintenance costs, better light quality without striations and dependable cold-weather starts.

Questions about this item
What is the minimum starting temperature for the GE 66339 ballast?
The ballast starts reliably down to -20F, making it suitable for cold environments such as unheated warehouses or outdoor signage.
What case temperature rating and ambient rating does the GE 66339 carry?
The case is rated for 90C maximum and the unit is UL approved for 55C ambient operation, so it runs cool even in warm ceiling plenums.
How is the GE 66339 wired for parallel lamp operation?
Connect each lamp to its own output leads on the ballast; the parallel design keeps the second lamp lit if the first reaches end of life, and the auto-restart feature restores light after brief power dips without cycling the switch.
