Each case ships as a 15-pack, giving electrical contractors and facility managers an efficient way to stock up for multi-fixture replacement or scheduled maintenance projects without ordering individual lamps.

  • Bulk Packaging: Sold in a 15-pack case quantity, streamlining ordering for larger relamping and maintenance projects.

Philips Lighting 9.2789E+11 – Frequently Asked Questions

1) What does CW mean on these Philips fluorescent tubes, and will they match the tubes already in my building?
CW is cool white, the classic 4100K-range fluorescent color. If the tubes currently in your fixtures are marked CW, these will match. If they read WW (warm white), D (daylight) or a number like 841 or 850, the color will read noticeably different in the same room. When you are relamping a whole bay or corridor, do the entire run at once so you are not mixing colors in adjacent fixtures.
2) Can I replace F48T12/CW/HO with a T8 lamp instead?
Not as a straight swap. A T12 HO lamp and a T8 lamp use different ballasts, and the HO version here uses recessed double contact ends while T8 lamps use medium bipin. Converting a T12 HO fixture to T8 means changing the ballast and, in most cases, the lampholders. If you want to keep the existing fixtures and ballasts running, stay with the F48T12 HO lamp; if you are retrofitting the fixture anyway, that is the point to decide on a new lamp type.
3) How do I order the exact Philips 4-foot HO cool white lamp so I get the right one?
Order by Philips part number 927890203305, lamp designation F48T12/CW/HO ALTO, supplied 15 per pack. Quoting both the number and the F48T12/CW/HO code protects you against being shipped a standard output F40T12 or a different color temperature, which are the two most common mix-ups on this lamp.
4) What does the ALTO designation mean on this Philips lamp?
ALTO is Philips' designation for their low mercury lamp construction, identified by the green end caps. It is the same electrical and physical lamp as the standard version, so it drops into the same HO fixture - the difference is in disposal handling for facilities tracking lamp waste. Institutional and government buyers usually specify ALTO for that reason.
