Product Overview
The Sylvania F40/WX combines a 3500K color temperature with 87 CRI for natural-looking color rendering in color-critical spaces. It is rated for 20,000 hours at 3 hours per start and 28,800 hours at 12 hours per start; mean lumens of 1805 are measured at 40% of average rated life.
Life ratings are based on 3-hour operating cycles under specified conditions with a ballast meeting ANSI specifications. If the operating cycle is increased, average life increases accordingly. Rated life is measured on 2-lamp rapid start magnetic ballasts, and life on single-lamp rapid start ballasts may be reduced.
Compatible Applications
- 4-foot fluorescent fixtures
- Color-critical lighting where high CRI is required
- Replacement for 40W T12 rapid start lamps; 40W rapid start lamps may also be used in starter-operated fixtures designed for 40W preheat lamps (preheat life approximately 15,000 hours average)
Before Ordering – Verify
- Confirm the fixture is a T12, Medium Bipin (G13) fixture with a ballast that suits a 40W rapid start lamp.
- Confirm the fixture is suitable for the intended location. The previous listing mentioned indoor/outdoor use, which the manufacturer datasheet does not state; verify the fixture rating before using this lamp outdoors.
- Minimum starting temperature depends on the ballast — consult the ballast manufacturer.
Installation Notes
- The lamp should not touch any surface of the luminaire (high-frequency or 60Hz ballasted systems).
- On high-frequency ballasted systems, keep at least 3 mm between any part of the lamp and any conductive surface of the luminaire.
