Sylvania 20928 – Frequently Asked Questions

1) Can I use a T8 high output lamp instead of this T5 HO tube?
No. T8 and T5 are different diameters with different bases, so they are not interchangeable in the socket or on the ballast. A T8 HO lamp such as the Philips 236794 (44-watt, 4100K, Alto series) only goes into a T8 HO fixture. If your fixture has G5 miniature bi-pin sockets, you need a T5 lamp like the 24-watt Pentron HO; if it has medium bi-pin T8 sockets, go the Philips T8 route.
2) Can a Philips 236794 T8 high output lamp be used in place of a Sylvania 20928 T5 HO fixture?
No. The Sylvania 20928 Pentron HO Ecologic is a T5 High Output lamp with a 2-pin G5 miniature base, 24 watts, 24 inches long. The Philips Lighting 236794 is a T8 high output fluorescent lamp rated 44 watts at 4100K. T8 lamps use a larger tube diameter and a medium bi-pin base, so they do not seat in a G5 T5 HO socket, and the ballast is different as well. If the fixture is T5 HO, stay with the T5 HO lamp.
3) What color temperatures does the Sylvania Pentron HO Ecologic 24W T5 lamp come in?
Two: 3000K warm white (part number 20928) and 4100K cool white (part number 20931). If you are relamping a space, pick one and stay with it. Mixing 3000K and 4100K tubes in the same run of fixtures reads as a visible color mismatch on the ceiling.
4) Is 3000K or 4100K the better choice for a retail space versus a warehouse?
3000K (model 20928) is a warm white and is the usual pick for retail sales floors, hospitality, and display lighting where you want an inviting tone. 4100K (model 20931) is a neutral cool white and is what most offices, warehouses, and back-of-house areas are already lit with, so it is the one that matches existing stock in those buildings. Both are 24-watt T5 HO lamps rated at 1750 lumens with 85 CRI, so output and color accuracy do not change between them.
5) How much light does a 24-watt T5 HO lamp actually put out?
1750 lumens from 24 watts. That is the high-output version of a 2-foot T5, so you get noticeably more light per fixture than a standard-output 2-foot T5 at the same physical length, which is why these get specified for warehouse, industrial, and tall-ceiling applications where fixture count is limited.
6) For a color-critical retail display, how does the Sylvania 20928 compare with the Philips Alto II high CRI lamp?
The Sylvania 20928 Pentron HO Ecologic T5 HO lamp is rated 85 CRI at 3000K, with 1750 lumens from 24 watts, and a 4100K version is also offered under part number 20931. The Philips Lighting 479634 Alto II is a high CRI linear fluorescent, but it is a T8 lamp, so it suits T8 fixtures rather than T5 HO sockets. Choose by the fixture's lamp type first, then by color temperature.
7) Is 85 CRI good enough for merchandising and color-critical display lighting?
85 CRI is the standard high-color-rendering tier for commercial fluorescent and is what most retail, office, and display specs call for. The Pentron HO Ecologic T5 lamp carries that 85 CRI rating, so merchandise and finishes render accurately under it. For art or print color proofing where 90+ CRI is written into the spec, you would need a higher-CRI lamp instead.
8) I need higher color accuracy than 85 CRI for a linear fluorescent job. What else is there?
For a high-CRI linear lamp, the Philips 479634 Alto II is a high-CRI T8 linear fluorescent. It is a T8, though, so it only works in T8 fixtures with medium bi-pin sockets. It will not go into a T5 HO fixture that takes a G5 base lamp like the 24-watt Pentron HO Ecologic.
9) What does the Ecologic designation on the Sylvania Pentron HO lamps mean for disposal in my facility?
Ecologic is Sylvania's low-mercury fluorescent platform, built for facilities running environmentally conscious lighting programs. It does not make the lamp exempt from fluorescent handling rules, though. All fluorescent tubes still contain mercury and should be recycled through your normal lamp recycling stream rather than put in the trash.
