Sylvania Pentron® Ecologic® T5 High Performance Linear Fluorescent Lamp

The Sylvania Pentron® Ecologic® T5 High Performance Linear Fluorescent Lamp family covers three lamp models – 20868, 20901, and 20921 – built for commercial and industrial spaces that demand consistent, high-quality illumination from standard T5 fixtures. Each lamp in the family shares a 2-Pin Miniature Base for straightforward installation, a dimmable design for flexible light-level management, and the Pentron® Ecologic® platform engineering that defines Sylvania's T5 High Performance lineup. Representative performance from the 20901 model – a 48-Inch length lamp drawing 28-Watts and delivering 2600 - 2900-Lumens with an 82 CRI rating at 3500K color temperature – illustrates the level of output and color accuracy facility managers and electrical contractors can expect from this lamp family when specifying for offices, retail environments, warehouses, and other T5-served applications.

Sylvania 20901 – Frequently Asked Questions

1) Can I run these Sylvania T5 lamps on a dimming system?
Yes, the Pentron Ecologic T5 High Performance lamps are a dimmable design, so they work with dimming controls for light-level management. The ballast has to be a dimming ballast as well; a lamp marked dimmable will not dim on a fixed-output instant-start ballast.
2) Can a Philips T8 lamp be used in place of the Sylvania Pentron Ecologic 28W T5?
No. The Sylvania Pentron Ecologic lamp is a T5 linear fluorescent with a 2-pin miniature base, while the Philips Lighting 236794 is a T8 high output lamp rated 44-Watt at 4100K. T5 and T8 are different tube diameters with different base and ballast requirements, so a T8 lamp will not seat or operate in a T5 fixture. Match the fixture's tube type before ordering.
3) What model number do I order to standardize T5 lamping across a building?
Order by the four-digit Sylvania model: 20868, 20901 or 20921. All three are 48-inch Pentron Ecologic T5 High Performance lamps on the 2-pin miniature base, so spec one model across the facility and your stockroom carries a single tube for every 4-foot T5 fixture. The 20901 is the 28W, 3500K, 82 CRI version.
4) Is 3500K the right color temperature for an office or retail space?
3500K is a neutral white, which is the common middle ground for commercial interiors, warmer than 4100K cool white and cooler than 3000K. Paired with the 82 CRI on the 20901, it renders merchandise and finishes accurately enough for offices, showrooms and classrooms. If the rest of your building is lamped at 4100K, the 3500K will read visibly warmer in the same sightline.
5) How much light does a 28-watt T5 lamp put out, and how many do I need for a warehouse bay?
The 20901 draws 28 watts and delivers 2600 to 2900 lumens per lamp, roughly 93 to 104 lumens per watt. Fixture count comes down to mounting height, reflector and target footcandles, but on a per-lamp basis you are planning around 2600 lumens as the conservative figure for layout.
6) If color accuracy matters more than anything else, is there an alternative to the 82 CRI Sylvania Pentron Ecologic T5 lamp?
The Sylvania Pentron Ecologic T5 lamp is rated 82 CRI at 3500K. Where higher color rendering is the priority and the fixture takes T8 lamps, the Philips Lighting 479634 Alto II is a T8 high CRI linear fluorescent lamp. Note it is a T8, not a T5, so it suits a different fixture - it is an alternative for the room, not a drop-in for a T5 socket.
7) We need dimming on a fluorescent lamp - how does the Sylvania Pentron Ecologic T5 compare with the Philips Alto lamps?
The Sylvania Pentron Ecologic T5 High Performance lamp is a dimmable design, which is what makes it a fit for offices and retail spaces running light-level controls. The Philips comparables are catalog alternatives in different tube formats: the 236794 is a T8 high output lamp in the Alto series and the 479634 is a T8 high CRI lamp in the Alto II series. If the control system is driving a T5 dimming ballast, stay with the T5 lamp.
8) Is the Sylvania Pentron Ecologic 28W T5 lamp a higher output lamp than a Philips T8 high output?
They are not the same output class. The Sylvania Pentron Ecologic T5 lamp draws 28-Watt and delivers 2600 to 2900 lumens at 3500K. The Philips Lighting 236794 is a 44-Watt T8 high output lamp at 4100K, so it is a higher-wattage lamp in a cooler color and for a different socket. For a T5 fixture, output has to come from a T5 lamp.
