GE Lightech 66883 Ballast

This GE Lightech 66883 is a constant-current electronic ballast rated for 18 watts output. It accepts a universal 120-277 volt input at 50 or 60 hertz and delivers 700 milliamps across a 4 to 26 volt range. The unit supports trailing-edge dimming and uses bottom-feed wiring. It is approved for dry and damp locations and ships in a case of six.

Installers needing 700mA constant current

This ballast suits LED loads that require exactly 700 milliamps within the stated voltage window. Projects using a different drive current, a higher power rating, or a dimming method other than trailing-edge will need a different unit. Fixtures wired for top-feed or side-feed connections are also incompatible with the bottom-feed design.

700mA constant-current output

The single specification that determines fit is the 700 milliamp constant-current output. The driver must match the LED module’s rated current; a mismatch will cause under-drive or over-drive. Verify the module’s current rating before selecting this ballast.

Questions about this item

What LED module voltage range does the 700 mA ballast support?

The driver maintains a constant 700 mA across an output range of 4 V to 26 V.

Will the driver dim properly with my existing trailing-edge dimmer?

Yes — it is rated for TE dimming on 120-277 V, 50/60 Hz circuits.

How can I confirm the ballast is operating correctly after wiring?

Measure the output with a multimeter; you should read a steady 700 mA between 4 V and 26 V.
