Philips Lighting 280974 – Frequently Asked Questions

1) Will the Philips F25T8 ALTO Plus fit my existing 3-foot T8 fixture?
Yes, if the fixture takes a 36 inch T8 lamp. The F25T8 ALTO Plus is a nominal 36 inch T8 tube with a medium bi-pin base, which is the standard 3-foot T8 lampholder arrangement. It drops into sockets currently holding a 30W F30T8 three-footer as long as the ballast is rated for the lamp.
2) How long does a Philips F25T8 ALTO Plus last, and does my ballast change that?
It changes it a lot. On programmed start the rated average life is 42,000 hours at 12 hours per start and 36,000 hours at 3 hours per start. On instant start it drops to 36,000 hours at 12 hours per start and 30,000 hours at 3 hours per start. Short cycling on instant start ballasts, typical of occupancy sensor zones, is what costs you the most life, so put these on programmed start ballasts anywhere the lights switch frequently.
3) 3000K or 4100K, which should I order for the F25T8?
Both are offered. 3000K, product number 280974, is the warm white one and suits hospitality, patient rooms, and retail where you want a softer look. 4100K, product number 280990, is the cool white and is what most offices, classrooms, and back of house areas are already running. The deciding factor is usually matching the tubes in the adjacent fixtures, since mixing color temperatures in one space is immediately obvious.
4) What does the green base on this Philips 25W T8 tube mean?
The green end cap marks it as an ALTO Plus low-mercury lamp. Mercury content is 1.7 mg per tube. Facilities that segregate lamp waste use the green base as a quick visual check on the crew's cart, though low-mercury lamps still go to a lamp recycler in most jurisdictions.
5) How much light does the 25W F25T8 put out compared with a standard 3-foot T8?
2150 initial lumens, settling to 2045 design mean lumens over life. It is an energy-saving lamp at 25W, so it draws less than a standard 30W three-foot T8 and puts out proportionally less light. In a space already lit to spec with 30W lamps you may see a noticeable drop, so it is best used where there is light to spare or where the whole area is being relamped together.
6) Is 85 CRI good enough for retail displays or a clinical area?
85 Ra is solid for general commercial work, showrooms, classrooms, and patient areas, where accurate skin tone and fabric color matter but critical color matching does not. For paint matching, print proofing, or color inspection work you want a high-CRI lamp in the 90 plus range instead.
7) How do Philips F25T8 tubes come packed for a relamp job?
Case quantity is 30 lamps. Order in full cases for a floor relamp and the count works out cleanly across a typical two-lamp or three-lamp troffer layout.
