Product Overview
The Sylvania 25146 F48T12CWHO is a high-output T12 fluorescent lamp engineered for demanding fixtures that use 800mA rapid-start ballast systems. Its 60-watt rating, R17d recessed double-contact bases, and approximately 46-inch overall length distinguish it from standard F40T12 and F32T8 fluorescent lamps.
The lamp produces 4,050 initial lumens at 4200K with a CRI of 60. Its cool-white output is intended for applications where brightness and system compatibility are more important than high color-rendering performance.
This lamp requires a compatible high-output rapid-start ballast. A similar physical appearance or matching nominal length does not establish compatibility. The ballast label, lamp current, wattage, starting method, base configuration, and fixture dimensions must all match before installation.
Compatible Applications
- Grocery lighting
- Refrigeration cases
- Canopy lighting
- Signage
- Display lighting
- Cold-temperature applications using compatible ballast equipment
- Maintenance replacement where Sylvania product number 25146 is specified
Before Ordering – Verify
- Product number: Confirm Sylvania NAED 25146.
- Ordering abbreviation: Verify F48T12CWHO.
- Lamp type: This is a T12 High Output 800mA lamp, not a standard-output T12 lamp.
- Wattage: Confirm the fixture and ballast are designed for a 60W F48T12 HO lamp.
- Starting method: Use only with a compatible rapid-start ballast.
- Base: Confirm the fixture uses R17d recessed double-contact lampholders.
- Color: This version is 4200K Cool White with CRI 60.
- Dimensions: Verify approximately 45.91 inches overall length and 1.59 inches diameter.
- Ballast compatibility: Check the ballast label for exact F48T12 HO and 800mA lamp compatibility.
- Cold-temperature starting: Minimum starting temperature depends on the ballast; consult the ballast manufacturer.
- Fixture clearance: The lamp should not contact any surface of the luminaire.
- Sibling products: Do not substitute F72T12, F84T12, F96T12, standard-output T12, VHO, or LED tubes solely because they use similar-looking recessed bases.
- Packaging: One lamp per SKU and 30 lamps per case.
Safety and Handling Guidelines
- Disconnect and lock out electrical power before inspection, installation, maintenance, or removal.
- Use only in fixtures designed for F48T12 High Output 800mA rapid-start lamps.
- Confirm the ballast is compatible with the exact lamp type and wattage.
- Do not force the recessed contacts into an incompatible lampholder.
- Fully seat and secure both lamp ends in the R17d sockets.
- Do not install a lamp that is cracked, chipped, loose, or otherwise damaged.
- Ensure the lamp does not touch any part of the luminaire housing.
- Allow the lamp and fixture to cool before handling.
- Minimum starting temperature is determined by the ballast and system configuration.
- Installation and ballast service should be performed by qualified personnel.
Compliance
