Philips Signify Advance Core Coil Ballast Kit 71A5390-001D 100W M90 Metal Halide (F). 

This is a brand new overstock item. I opened the package only to verify all parts are present in new condition.

These are made by Signature, formerly Philips due to a recent name change of Philips' lighting division
