Sylvania 22136 – Frequently Asked Questions
1) Do I need to change the ballast to use these 17W T8 lamps?
No ballast change is needed if the fixture is already a T8 fluorescent fixture. The Octron 800 Ecologic is a 17W fluorescent tube with a 2-pin medium base, so it runs on the existing T8 fluorescent ballast. These are not LED replacement tubes, so there is no bypass or rewiring involved.
2) Which model number do I order for 3500K Octron 800 Ecologic lamps?
Model 22136 is the 3500K, 17-watt, 82 CRI lamp. The series is also offered as models 20949 and 23476, which are tuned to different color temperatures and lumen packages. If you are matching existing tubes in a building, read the model number printed on the end cap of the lamp you are pulling out rather than ordering by series alone.
3) Can I use a Philips 236794 T8 lamp in place of a Sylvania Octron 800 Ecologic 24-inch lamp?
No. The Philips 236794 is a T8 high output fluorescent lamp rated 44 watts at 4100K, which is a high output lamp on a different ballast class and a cooler color than the Sylvania Octron 800 Ecologic, a 17W 3500K lamp with 1350 lumens in a 24-inch length. Both share the T8 tube diameter, which is what makes them look interchangeable on the shelf, but a 44W high output lamp will not operate correctly on a 2-foot 17W T8 instant or rapid start ballast. Keep the 44W Philips for high output fixtures and use the Octron for standard 2-foot T8 housings.
4) What color temperature and light level do these 2-foot Sylvania T8 tubes put out?
3500K neutral white at 1350 lumens, with an 82 CRI. That is the middle ground between warm 3000K and cool 4100K, and it is the common choice for offices, retail, and classrooms where you want the light to read white without going blue. The 82 CRI is adequate for general illumination and merchandise display, though a color-critical space would want a high-CRI lamp.
5) Is the Philips Alto T8 a direct substitute for these Sylvania Octron lamps?
Not a direct one-for-one. The Philips Lighting 236794 is a T8 high output lamp at 44 watts and 4100K, which is a different wattage class and color temperature than the 17W 3500K Octron 800 Ecologic. High output T8 lamps also require an HO-rated ballast. For a closer color-rendering alternative, the Philips Alto II T8 high CRI linear fluorescent lamp is the high-CRI option in the same lamp family.
6) My fixtures are 4100K Philips Alto lamps - will the Sylvania Octron 800 Ecologic match them?
Not on color. The Philips Alto 236794 is a 4100K lamp, a cool white, while the Sylvania Octron 800 Ecologic is specified at 3500K, a neutral white. Mixed in the same room or the same two-lamp fixture, the difference is visible as a warm-cool shift across the ceiling. If you are standardizing a facility, relamp a full room or zone at one color temperature rather than mixing the 3500K Octron into 4100K fixtures.
7) If color accuracy matters more than anything, should I specify the Sylvania Octron 800 Ecologic or a Philips high CRI lamp?
For spaces where color judgement matters - retail display, paint or fabric areas, print inspection - the Philips Alto II line is built and sold specifically as a high CRI T8 lamp, so it is the one to price out when CRI is the driving spec. The Sylvania Octron 800 Ecologic carries 82 CRI at 3500K with 1350 lumens, which covers general office, retail and warehouse illumination where neutral-white color and steady lumen output are the requirement rather than critical color matching.
8) Is a 17W 2-foot T8 lamp bright enough for warehouse or industrial general lighting?
At 1350 lumens per lamp, a single 2-foot tube is a low output source. In warehouse and industrial bays these are used in multi-lamp fixtures or in task and undershelf locations, not as the sole high-bay source. For broad general illumination over open floor area, the 4-foot T8 lamps carry far more lumens per fixture and are the usual specification.
9) What does the Octron 800 Ecologic designation actually mean on a Sylvania T8 lamp?
Octron 800 is Sylvania's 800-series T8 linear fluorescent platform, where the 8 indicates the 80s CRI range, matching the 82 CRI on the 17W 3500K lamp. Ecologic is Sylvania's designation for its reduced-mercury lamp construction. Together they tell you this is a standard 80-CRI T8 built on the low-mercury platform, which is what most facilities specify for routine relamping.
