Philips Lighting 579425 – Frequently Asked Questions

1) Will the Philips CorePro T8 LED lamp fit my existing fluorescent T8 fixture sockets?
The CorePro T8 LED lamp uses a G13 medium bi-pin base, which is the same base as standard linear fluorescent T8 tubes, so it drops into existing T8 lampholders. Philips positions it as a direct upgrade for fluorescent T8 fixtures.
2) What is the difference between the Philips CorePro T8 LED lamp and the Sylvania Octron 800 Ecologic T8?
Both are linear T8 lamps, but they use different light sources. The Philips CorePro is a T8 linear LED lamp drawing 14.5 watts on a G13 medium bi-pin base and producing 2100 initial lumens at 80 CRI. The Sylvania Octron 800 Ecologic is a T8 fluorescent lamp series, so it operates on the fluorescent ballast in the fixture rather than as a solid-state retrofit. If you are keeping existing fluorescent tubes and ballasts in service, the Octron 800 Ecologic is the like-for-like fluorescent replacement; if you are converting the fixture to LED, the CorePro T8 is the lamp built for that upgrade.
3) We have been buying Sylvania 22438 Octron Vivid Value tubes for our offices. Can the Philips CorePro T8 replace them?
They serve the same T8 openings but differently. The Sylvania 22438 is an Octron Vivid Value Ecologic3 T8 fluorescent lamp, a fluorescent tube. The Philips CorePro T8 is a 14.5-watt LED lamp on a G13 medium bi-pin base rated 2100 initial lumens at 80 CRI, intended as an energy-saving upgrade from linear fluorescent tubes. Before you standardize a floor on the CorePro, confirm how the fixture is wired and ballasted, since fluorescent and LED linear lamps have different fixture requirements. For a straight tube-for-tube reorder with no fixture work, the 22438 stays the matching fluorescent item.
4) How much light does a 14.5W LED T8 put out compared to the fluorescent tube I am pulling out?
The CorePro T8 draws 14.5 watts and delivers 2100 initial lumens. That output covers general-purpose ambient lighting in offices, retail, warehouse and institutional spaces at roughly half the wattage of the legacy linear fluorescent tubes it is meant to replace.
5) Can I use the CorePro T8 LED lamp on a dimmer?
The CorePro T8 is a general-purpose linear LED for straightforward fluorescent T8 replacement and is not presented as a dimming lamp. For dimmable work, the Sylvania Ultra LED series and the Topaz LP166 series PAR16 are dimmable lamps, though both are different lamp shapes, not linear T8 tubes.
6) I need to standardize lamps across a whole facility. Which part numbers do I order?
Two order numbers cover the 14.5W CorePro T8: 579425 for 4000K cool white and 579433 for 5000K daylight. Everything else is identical between them, 2100 lumens, 80 CRI, G13 bi-pin base, so you can standardize on one MPN per building and keep a single spare on the shelf.
7) Is 80 CRI good enough for an office or retail retrofit?
At 80 CRI, the CorePro T8 handles everyday visual tasks in offices, classrooms, warehouses and general retail without color problems. If you are lighting merchandise where color accuracy sells the product, such as apparel or paint displays, you would want a higher CRI lamp instead.
