Six-Tube Octron T8 Fluorescent Kit

This pack contains six Sylvania Octron T8 fluorescent tubes, each 24 inches long and rated at 17 watts. They deliver 5000 K colour temperature with 800 lumens per lamp and a 90 CRI rating. The Medium Bi-pin G13 base fits standard T8 fixtures. Supplied as a case of six new lamps.

Suits Commercial and Institutional Relamping

Facilities managers stocking troffers, wraparounds or industrial strips will appreciate the consistent 90 CRI output across all six tubes. Buyers needing dimmable LED replacements or instant-start ballast compatibility should verify their gear before purchasing. The straight-tube form factor does not suit compact or circular fixtures.

17-Watt 24-Inch T8 with 5000 K and 90 CRI

The decisive specification is the 17-watt, 24-inch T8 envelope combined with 5000 K colour and 90 CRI. Match this wattage, length and base type to the ballast and fixture labels. If the existing system calls for a different wattage, length or colour rendering index, these lamps will not operate correctly.
