Sylvania 22438 – Frequently Asked Questions
1) Will the Sylvania 22438 fit a standard 4-foot T8 troffer?
Yes. The 22438 is a 48-inch T8 linear lamp with a medium bi-pin base, which is the standard socket on 4-foot T8 troffers and strip fixtures. If your existing lamps are 4-foot T8s with two pins at each end, this drops straight into the same lampholders.
2) Is a 32W T8 lamp like the Sylvania 22438 compatible with my existing ballast?
The 22438 is a 32-watt T8 fluorescent tube, so it needs a fluorescent T8 ballast, either instant-start or program-start, matched to 32W F32T8 operation. It will not run on a line-voltage socket and it is not a direct swap into a fixture that has been converted to a ballast-bypass LED tube. If your fixture currently runs F32T8 lamps, this is the same lamp type.
3) Will a 4100K lamp match the tubes already in my building?
4100K is cool white, the most common commercial fluorescent color temperature, so the 22438 will usually match existing office and warehouse tubes. Watch the color rendering though: at 90 CRI this lamp renders color more vividly than a standard 700-series 32W T8, and in the same room beside a lower-CRI tube the difference is visible. If you are relamping a space piecemeal, do it fixture by fixture or room by room rather than mixing within one fixture.
4) What is the closest alternative to the Sylvania 22438 if I need high color rendering in a 4-foot T8?
The Sylvania 22438 is a 32W, 48-inch T8 lamp rated 90 CRI at 4100K with 2450 lumens on a medium bi-pin base. The closest alternative for color-critical work is the Philips 479634 Alto II T8 high CRI linear fluorescent lamp, which is also built as a high CRI linear T8. Retail display and merchandising areas where color accuracy matters are the usual reason to be choosing between the two; for general office or warehouse light where color rendering is not critical, a standard 700-series T8 is the more common pick.
5) Can I use a Philips 236794 in place of a Sylvania 22438?
They are not interchangeable in the same fixture. The Sylvania 22438 is a 32-watt T8 for standard rapid or instant start T8 ballasts, while the Philips 236794 is a 44-watt T8 high output lamp, and high output lamps require a ballast matched to that lamp current. Both are 4100K, so the light color will look the same, but you cannot drop a 44W high output tube into a fixture ballasted for a 32W T8 and expect rated performance. Match the lamp to the ballast label inside the fixture.
6) How much light will I get per fixture with the Sylvania 22438?
Each lamp puts out 2450 lumens, so a two-lamp 4-foot troffer gives about 4900 lumens of lamp output and a three-lamp fixture about 7350, before fixture and ballast losses. That is useful math when you are checking whether a relamp holds your footcandle level in an office or classroom.
7) What else could I buy instead of the Sylvania 22438 if I need a high CRI 4-foot T8?
Philips Lighting 479634, from the Alto II line, is the other high-CRI linear fluorescent T8 we carry and is the closest cross-brand alternative. If your fixtures are high-output rather than standard 32W, the Philips 236794 is a 44-watt T8 high-output lamp at the same 4100K, but it is not interchangeable with a 32W lamp on a standard T8 ballast.
8) Can I use the 22438 to relamp a whole school or office building on one standard?
Yes, and that is the practical case for it. A single part number covers every standard 4-foot two-lamp or three-lamp T8 fixture in the building at 4100K and 90 CRI, which keeps stockroom SKUs down and keeps color consistent from room to room. The one place it does not work is high-output fixtures, which need a 44W HO lamp such as the Philips 236794 instead.
9) If I am standardizing 4100K lamps across a facility, which of these lamps keep the same light color?
The Sylvania 22438 is 4100K, and the Philips 236794 T8 high output lamp is also 4100K, so both read as the same cool white on the wall. Where they differ is the electrical side: the 22438 is a 32-watt standard T8 and the 236794 is a 44-watt high output, so standardizing on color alone is not enough. Group fixtures by ballast type first, then pick the 4100K lamp that matches each ballast group.
