ABSTRACT:
A device and method for converting a fluorescent down-light into an up-light or combined up-down-light involves suspending a luminaire body from a ceiling below a pre-existing down-light. Ballast lead extenders connect lamp holders in the luminaire body to the lamp holders in the pre-existing down-light. A reflective panel is inserted above the luminaire body serving the dual purposes of hiding the down-light and downwardly reflecting the light which emanantes from the luminaire body.
