- What fixtures does this tube fit?
- It is a 4 ft T8 tube with a G13 medium bi-pin base, so it fits standard 4 ft T8 fluorescent fixtures and troffers. The fixture's ballast must be rated for 32 W T8 lamps.
- What color light does it give off?
- It is rated at 3500K, a neutral bright white. That sits between warm 3000K and cooler 4000K to 5000K lamps, so it reads fairly neutral in offices and workspaces.
- How does it compare with a standard T8 tube?
- Output and wattage are typical for a 32 W T8 at about 2,950 lumens. The difference is the ALTO II low-mercury design at 1.7 mg per tube, which helps where disposal rules limit mercury content.
- How long does one tube last?
- Philips rates average life at 24,000 hours. That is roughly several years of typical office use, though switching frequency and ballast type affect real life.
- Can I put these in an LED fixture?
- No. These are fluorescent tubes that need a fluorescent ballast. LED retrofit fixtures and direct-wire LED tubes use different wiring and drivers.
- How should I dispose of old tubes?
- Fluorescent tubes contain mercury and should go to a recycling or hazardous-waste drop-off rather than household trash. The low 1.7 mg mercury content helps with many disposal thresholds.
