Philips Lighting Alto T8-6U U-Tube Fluorescent Lamp

The Philips Lighting Alto T8-6U U-Tube Fluorescent Lamp is engineered for reliable general illumination in commercial and institutional fixtures. This 32-Watt lamp delivers 2500 lumens of light output with an 84 CRI rating, and is available in a choice of color temperature — from 3500K Neutral White up through 5000K Daylight — so facility managers can match the lamp to the ambiance and color-rendering needs of a given space. Built on a 2-Pin G13 base with a compact 22.44-inch length, the U-shaped bulb configuration allows it to fit troffer and recessed fixtures where a straight linear tube will not, making it a practical retrofit and replacement option. As part of the Philips Alto® lamp family, it is manufactured using Philips' low-mercury Alto technology for reduced environmental impact without sacrificing light quality or lamp life.

  • Wattage: 32-Watt energy draw balances light output with operating efficiency across both color temperature options.

Philips Lighting 379008 – Frequently Asked Questions

1) Will the Philips Alto T8-6U U-tube lamp fit a 2x2 troffer that won't take a straight 4-foot T8?
That's exactly the case this lamp covers. The T8-6U is a bent U-tube roughly 22.44 inches long, so it drops into recessed troffers and compact fixtures where a straight 48-inch linear T8 has no room. It uses the same 2-pin G13 bi-pin base as standard T8 lampholders, so the sockets in a U-tube troffer accept it directly.
2) Will a 32W U-tube fluorescent lamp run on my existing troffer ballast?
The T8-6U is a 32W G13 bi-pin fluorescent lamp, so it needs a working T8 fluorescent ballast in the fixture, instrument-start or programmed-start depending on what is installed. It is not an LED retrofit tube and will not operate on line voltage with the ballast bypassed. If the fixture has already been converted to direct-wire LED, this lamp is the wrong part for it.
3) What is the closest U-tube alternative to the Philips Alto T8-6U 32W lamp?
The Sylvania 21878 FBO31/835 T8 U-Tube Fluorescent Lamp is the nearest U-bent equivalent. It is a 31W T8 U-tube at 3500K, against the Philips Alto T8-6U at 32W with a G13 base and 2500 lumens at 84 CRI. Both are bent-tube T8 lamps intended for troffers and compact fixtures where a straight linear tube will not fit, so if you are matching a 3500K neutral white installation the Sylvania 21878 covers the same color point as the Philips 379008 version.
4) Can I use a Sylvania 22207 Octron 800 HO instead of the Philips Alto T8-6U?
No - those are not interchangeable fixtures. The Sylvania 22207 is a 96-inch straight T8 lamp in the Octron 800 HO/Ecologic series, which needs an 8-foot linear strip fixture. The Philips Alto T8-6U is a bent U-tube roughly 22.44 inches long on a 2-pin G13 base, sized for compact troffer and recessed fixtures where a straight tube will not fit. If your fixture takes U-tubes, stay with a U-bent lamp.
5) How does the Philips Alto T8-6U compare to the Sylvania Octron Curvalume U-tube lamps?
Both are T8 U-tube lamps for the same compact troffer applications. The Philips Alto T8-6U is a 32W lamp at 2500 lumens and 84 CRI, in 3500K or 5000K. The Sylvania alternatives ZenSupply carries are the 21878 (FBO31/835, Octron Curvalume, 31W, 3500K) and the 21879 Octron 800 Curvalume, also 31W. The 31W Sylvania lamps are the reduced-wattage energy-saver version of the same form factor, so if your fixtures and ballasts were specified around full 32W T8 operation the Philips lamp is the straight match; if you are already standardized on 31W energy-saver lamps, stay with the Octron.
6) Is the Philips T8-6U bright enough to replace two straight T8 lamps in a 2x2 fixture?
Each T8-6U puts out 2500 lumens at 32W. A 2x2 troffer is normally lamped with two U-tubes, which gives about 5000 lumens at the fixture, so order per socket rather than treating one U-tube as a two-lamp replacement. With 84 CRI it is suited to general office, retail and institutional ambient lighting rather than color-critical work.
7) I need U-tubes for a 2x2 and 8-foot straight lamps for the warehouse. Can I standardize on one Sylvania or Philips line?
Not on a single lamp, no. The Philips Alto T8-6U covers the 2x2 and compact troffer sockets in a U-tube form. For 8-foot straight runs ZenSupply carries the Sylvania 22207 Octron 800 HO T8, a 96-inch lamp. Different lengths and ballast types, so expect two line items; what you can standardize is the color temperature across both so the building reads consistently.
8) What does one Philips T8-6U U-tube lamp weigh for shipping and handling on a relamp?
Each lamp is listed at 0.642 lb. On a large relamp that matters mainly for cart loads and recycling box weight limits, since U-tubes nest poorly compared to straight tubes.
