where to buy prismatic rectangular wraparound flourescent lens 48" x 10" for older 2 t12 non-electronic ballast unit?
Can't find anything in local home depot, orchard supply, lamp stores so far (northern california). All those places seem to have switched over to 48" x 8" t8 electronic ballast units.
Must i replace the entire unit by t8 electronic ballast unit just if the lens cracks?
Thanks in advance.
