Philips Master PL-T 26W/840/2P

Philips Master PL‑T 26W/840/2P – Compact Fluorescent Lamp Overview

The Philips Master PL‑T 26W/840/2P is a high‑performance compact fluorescent lamp (CFL) designed for general lighting applications. It combines efficient light output with reliable operation, making it suitable for residential, commercial and industrial environments.

Key Technical Specifications

• Wattage: 26 W
• Lumen Output: Approximately 1,800 lm (typical for a 26‑W CFL)
• Color Temperature: 4,000 K – Cool White
• Candela Radiant Intensity: 180 cd (standard for this class of lamp)
• Lifespan: Up to 10,000 hours under normal operating conditions
• Incandescent Equivalent: 200 W (provides a comparable brightness level with significantly lower energy consumption)
• Energy Efficiency Class: A (highest rating in the EU energy efficiency classification for lamps)
• Base Type: GX24d – 2‑pin, compatible with standard 4‑pin sockets when used with a suitable starter or ballast
• Dimensions: Approx. 11 cm in length and 13.7 cm in diameter (standard for the 840 series)
• Voltage Range: 100–240 V AC, allowing use across a wide range of electrical systems
• Starter Type: Integrated starter (no external ballast required)

Design and Construction Features

The lamp’s compact form factor is achieved through a carefully engineered phosphor coating that converts the ultraviolet light produced by the mercury vapor discharge into visible cool‑white light. The phosphor blend ensures high color rendering (CRI ≈ 80) while maintaining energy efficiency.

Its sealed glass envelope protects the internal components from moisture and dust, extending operational life in varied environments. The 2‑pin base is engineered for easy installation into standard fixtures that support the GX24d socket type.

Performance Characteristics

• Light Distribution: Even, diffuse illumination suitable for task lighting and ambient spaces.
• Color Rendering Index (CRI): 80 – provides natural color perception for objects and surfaces.
• Correlated Color Temperature (CCT): 4,000 K – delivers a crisp, cool white that enhances visibility in work areas.
• Initial Light Output: 1,800 lm at the start of life; light output decreases gradually to about 70% after 10,000 hours.

Energy Savings and Environmental Impact

By replacing a traditional 200‑W incandescent bulb with this 26‑W CFL, users can achieve an energy reduction of approximately 87%. Over the lamp’s lifespan, this translates into significant savings on electricity bills and a lower carbon footprint.

The A efficiency rating indicates compliance with stringent European Union regulations for lighting products. This classification ensures that the lamp delivers high performance while minimizing energy consumption.

Installation Guidelines

1. Verify Socket Compatibility: Ensure the fixture supports a GX24d base or has an adapter to accommodate it.
2. Turn Off Power: Prior to installation, switch off the electrical supply to avoid shock hazards.
3. Insert Lamp: Align the two pins with the socket contacts and gently rotate until secure.
4. Restore Power: Turn the circuit back on; the lamp should light immediately thanks to its integrated starter.

Maintenance and Replacement

The Philips Master PL‑T 26W/840/2P is designed for minimal maintenance. When the light output falls below 70% of its initial value, or if the lamp fails to start after several attempts, it should be replaced. Disposal should follow local regulations for mercury-containing devices; many regions offer recycling programs specifically for CFLs.

Applications

• Residential: Living rooms, kitchens, bedrooms, and hallways.
• Commercial: Offices, retail displays, and small business premises.
• Industrial: Workstations, warehouses, and manufacturing areas where cool white illumination is preferred.

Compatibility with Other Systems

The lamp’s 100–240 V AC rating allows it to function in both low‑voltage and high‑voltage environments. Its integrated starter eliminates the need for external ballasts, simplifying installation in existing fixtures that previously used incandescent or halogen bulbs.

Conclusion

The Philips Master PL‑T 26W/840/2P offers a reliable, energy‑efficient lighting solution with a cool white output suitable for a wide range of settings. Its high efficiency class, long lifespan, and straightforward installation make it an attractive choice for users seeking to reduce energy consumption without compromising on light quality.
