Philips Lighting 290288 – Frequently Asked Questions

1) Will a Philips F54T5/835/HO/ALTO work in a standard T5 fixture, or does it need an HO ballast?
It needs a T5 high output ballast. The F54T5/835/HO/ALTO is a High Output (HO) system lamp drawing 54.1 W at a nominal lamp current of 0.455 A. A standard T5 fixture is built around the 28W-class normal-output lamp and will not run this tube properly even though the G5 bipin base is the same physical base on both. Check the ballast label for T5HO before ordering.
2) Is 3500K too warm or too cool for a warehouse or retail sales floor?
3500K is the neutral white middle ground, warmer than the 4100K and 5000K lamps common in industrial bays and cooler than 3000K residential-style light. The 835 color code means 80-series color rendering at 3500 K, with a nominal CRI of 82. For a retail sales floor it keeps merchandise looking natural without the clinical edge of 5000K. If you are relamping a building, match the existing color code rather than mixing 835 with 841 or 850 in the same space, since the difference is obvious side by side.
3) Will these T5HO lamps put out full light in an unheated warehouse or cooler in winter?
No. T5 lamps are optimized for a 35 degree C ambient design temperature, warmer than the 25 degree C point T8 lamps peak at. Below that the mercury pressure drops and output falls off, so in an unheated space or a walk-in cooler you will see noticeably less than the rated 5,000 lumens and slower starting. For cold locations use a fixture with an enclosed lens or specify low-temperature-rated lighting.
4) How do I identify this Philips T5 lamp against the one already in the fixture?
Two quick checks. The lamp is printed F54T5/835/HO/ALTO, and the Alto lamps carry a green end cap, so if the tubes in the fixture have green caps you are looking at the same low-mercury family. The Philips order number is 290288. Green cap plus the 835 code on the glass confirms you have a match for 3500K high output.
5) Can I dim these T5HO tubes?
The lamp itself is dimmable, but dimming is a ballast function. You need a dimming T5HO ballast and a compatible control; putting a dimmable lamp on a fixed-output ballast just gives you full output.
6) Does this Philips tube help with LEED or hazardous waste handling because of low mercury?
Mercury content is 1.4 mg per lamp, which is low enough that many low-mercury Alto lamps pass TCLP and are handled as ordinary waste in jurisdictions that allow it. Local rules vary and several states require fluorescent recycling regardless, so confirm with your waste hauler. For LEED documentation the 1.4 mg figure is the number your consultant needs for the mercury-per-lamp credit calculation.
7) How does a 54W T5HO compare to running two T8 lamps for the same light?
One F54T5/835/HO/ALTO delivers 5,000 initial lumens at 54.1 W, an efficacy of 83 lm/W. That is roughly the output of two 32W T8 lamps from a single tube, which is why T5HO is used in high bays and narrow reflector fixtures where you want the light from one small-diameter source. The tradeoff is brightness per tube: T5HO produces high surface luminance, so it needs a shielding lens or deep reflector in any space where the lamp is in the line of sight.
8) Is CRI 82 good enough for a healthcare or classroom space?
Nominal CRI is 82, with a tested range of 80 to 85. That clears the 80-CRI minimum that most school and healthcare lighting specifications and energy codes call out for general spaces. For color-critical work such as exam rooms or paint matching, a 90-plus CRI lamp is the better call.
