Sylvania 20902 – Frequently Asked Questions

1) Will a 28W T5 Sylvania Pentron Ecologic lamp fit my existing T5 fixture?
If the fixture takes a 48-inch T5 High Performance lamp on a 2-pin miniature base, yes. The Pentron Ecologic runs 28 watts on a 2-pin miniature base at 48 inches long, which is the standard T5HO-length socket spacing for 28W T5 high performance fixtures. What it will not do is drop into a T8 fixture; T8 lamps use a medium bi-pin base and a larger tube diameter, so the sockets will not accept it.
2) Do I need a dimming ballast for the Sylvania Pentron Ecologic T5 lamp, or will it dim on a standard one?
Dimming only happens if the ballast does it. The lamp is dimmable, but it has to be paired with a compatible T5 dimming ballast. On a standard fixed-output electronic ballast it will light normally at full output and the dimmer will do nothing, or worse, damage the ballast. Facility managers retrofitting for light-level control need to budget for the ballast as well as the lamp.
3) Can a Philips 236794 T8 lamp be used in place of a Sylvania Pentron Ecologic 28W T5?
No. The Pentron Ecologic lamp is a T5 High Performance linear fluorescent rated 28 watts with a 2-pin miniature base, while the Philips Lighting 236794 is a T8 high output fluorescent lamp rated 44 watts. T5 and T8 lamps use different tube diameters, sockets and ballast types, so a T8 lamp will not seat or operate in a T5 High Performance fixture. Match the lamp to the fixture's T5 sockets and dimming ballast.
4) What is the difference between models 20902, 20907, 20919 and 20924 in the Pentron Ecologic T5 line?
All four are 28-watt, 48-inch, 4100K, 82 CRI T5 lamps on a 2-pin miniature base, so they are interchangeable from a fixture and light-quality standpoint. Order by the model number your facility has standardized on: 20902, 20907, 20919, or 20924.
5) Will 4100K T5 lamps match the tubes already in my office ceiling?
4100K is cool white, the most common commercial office color temperature, so it will generally blend with existing office troffers running 4100K tubes. If the other fixtures are 3500K (warmer) or 5000K (bluer), the difference will be visible side by side. Color rendering is 82 CRI, which is standard for commercial fluorescent and will look consistent against other 82 CRI lamps.
6) If a fixture is T8 rather than T5, what 4100K lamp matches the Pentron Ecologic color appearance?
The Pentron Ecologic T5 lamps run 4100K cool white. For a T8 high output fixture, the Philips Lighting 236794 is also a 4100K lamp, so the color appearance stays consistent between T5 and T8 fixtures in the same building. The wattage and base differ, so specify by the fixture's lamp type and keep 4100K as the common value across both.
7) We need better color rendering than 82 CRI for a retail display. What are the options?
The Sylvania Pentron Ecologic T5 lamps are rated 82 CRI, which suits general office, retail and institutional lighting. Where a display area calls for higher color rendition, the Philips Lighting 479634 Alto II is a high CRI linear fluorescent lamp. It is a different lamp platform, so confirm your fixture accepts it before specifying; the Pentron Ecologic remains the match for T5 High Performance sockets.
8) What is the difference between the Sylvania Pentron Ecologic series and the Philips Alto and Alto II series?
Pentron Ecologic is Sylvania's dimmable T5 High Performance line, built on a 28 watt 48-inch tube with a 2-pin miniature base, 4100K and 82 CRI. Philips Alto is represented by the 236794 T8 high output lamp, and Alto II by the 479634 high CRI linear fluorescent lamp. The practical difference is lamp platform: the Sylvania family serves T5 High Performance fixtures with dimming ballasts, while the Philips lamps are linear T8-family products.
9) How much light does a 28W Pentron Ecologic T5 put out?
Rated at 2600 to 2900 lumens on 28 watts. For layout purposes that is roughly 93 to 104 lumens per watt, which is why these are used in office, retail and institutional spaces where a T5 high performance fixture is already in place.
10) Is 82 CRI good enough for retail display lighting?
82 CRI covers general retail, office and institutional task lighting, and it is the usual spec for commercial linear fluorescent. Where color accuracy drives the sale, such as apparel, paint or cosmetics displays, buyers typically step up to a high CRI lamp; Philips sells the Alto II high CRI T8 linear fluorescent for that kind of application, though it is a T8 and needs a T8 fixture.
