Philips Lighting 391169 – Frequently Asked Questions

1) Will a Philips FC16T9 circular fluorescent lamp fit my existing fixture?
The Philips circular fluorescent lamps in this family use a G10Q base, the four-pin circular base standard on T9 circline fixtures. If your existing lamp seats on a G10Q four-pin connector, these drop in. The other thing to match is the ring diameter, which is what the FC8T9, FC12T9 and FC16T9 designations tell you: 8 inch, 12 inch and 16 inch rings respectively. A 16 inch ring will not fit a fixture built for a 12 inch circline, so match the FC number on the old lamp.
2) Can I put these Philips circline lamps on a dimmer?
No. The Cool White Plus circline lamps are not dimmable. Wire them to a straight on/off switch on the existing magnetic or electronic circline ballast. If a space needs dimming control, this is the wrong lamp choice and you should be looking at a dimmable replacement fixture instead.
3) Will 4100K Cool White Plus match the circline lamps already in my building?
It matches anything running at 4100K neutral white, which is the common commercial fluorescent color along with 3000K and 5000K. The Philips Cool White Plus circline is 4100K with color code 33 and a Cool White (CW) designation. If the other fixtures in the space are 3000K warm white or 5000K daylight, mixing this lamp in will read visibly cooler or warmer than its neighbors. For a property manager standardizing a floor, note the color code 33 on the old lamp and order to match.
4) Is a CRI of 62 good enough for an office or retail space?
At a nominal CRI of 62, this circline lamp is adequate for general area and task lighting in offices, corridors, libraries and back-of-house areas, where seeing clearly matters more than color accuracy. It is not the right lamp where color judgment is part of the work: retail merchandise display, paint or fabric matching, or clinical exam areas. Those want a high-CRI source in the 80-plus range.
5) How long do these Philips circline fluorescent lamps last, and how much does output drop off?
Rated life is 13,000 hours to 50 percent failures. Light output holds at 87 percent of initial at 2,000 hours and 78 percent at 5,000 hours, so plan on a visible drop over the lamp's life. For an MRO group on a group-relamp schedule, that 13,000 hour figure is the number to build the interval around rather than waiting for individual failures.
6) Do these circline lamps contain mercury, and does that affect disposal?
Yes, each lamp contains a nominal 8.0 mg of mercury, as all fluorescent lamps do. That makes spent lamps a regulated waste stream in most jurisdictions, so they go to a lamp recycler rather than the dumpster. Institutional and government facilities typically already have a fluorescent lamp recycling program in place, and these go into it.
7) How much light does the 39.5W FC16T9 circline put out?
The FC16T9 39.5W version delivers 2,500 lumens initial at 4100K. That is the output level for a 16 inch circline in a ceiling-mount or wraparound fixture covering general room lighting, not a high-bay or a task-critical station. Running current is 0.42 A at a nominal 109 V lamp voltage, which is what the existing circline ballast has to support.
