ICN-2TTP40-SC Advance Electronic CFL Ballast - FT40W/2G11 Lamps

What is the Philips Advance ICN-2TTP40-SC?

The ICN-2TTP40-SC is a Centium series electronic fluorescent ballast manufactured by Philips Advance (now Signify). It is primarily engineered to operate one or two 40-watt twin-tube CFL lamps (FT40W/2G11), offering critical advantages including IntelliVolt universal voltage (120-277V), Lamp Striation Reduction (LSR), and a high-efficiency instant start mechanism. It is the optimal choice for retail, healthcare, and office environments requiring reliable, energy-efficient fluorescent lighting performance.

Core Features and Technical Advantages

Selecting a premium Centium electronic ballast ensures maximum energy efficiency and smooth operation for your commercial fixtures. The primary features of the ICN-2TTP40-SC include:

• IntelliVolt Technology: Automatically detects and operates on any voltage between 120V and 277V (50/60Hz), streamlining retrofits and maintenance by eliminating the need to stock multiple voltage-specific ballasts.
• Lamp Striation Reduction (LSR): Advanced integrated circuitry minimizes the visual "snaking" or flickering effect occasionally seen when cold-starting fluorescent tubes, ensuring perfectly consistent light output immediately upon activation.
• Instant Start Efficiency: Provides maximum energy savings and rapid illumination. It delivers a normal ballast factor (~0.88) with Total Harmonic Distortion (THD) under 10% for exceptionally clean power usage.

How to Verify Compatibility for Your Fixture

When evaluating the ICN-2TTP40-SC for a repair or retrofit, assess the following criteria to ensure complete compatibility with your setup:

1. Lamp Type and Count: Confirm your fixture utilizes one or two 40W 4-pin long compact fluorescent lamps (FT40W, PL-L40W, or 2G11 base). This specific model is not compatible with T5, T8, or standard linear tubes.
2. Switching Frequency: Because this utilizes an instant-start circuit, it is best suited for long-burn applications (lights left on all day). For restrooms or areas using occupancy sensors with frequent on/off cycles, a programmed rapid start ballast is heavily recommended instead to preserve lamp life.
3. Physical Dimensions: Verify that the low-profile SC-can metal housing (9.5" L x 1.7" W x 1.18" H) will fit properly within your fixture's internal ballast channel.

Frequently Asked Questions

What lamps are compatible with the ICN-2TTP40-SC?

This ballast is designed strictly for standard FT40W/2G11 and PL-L40W/2G11 long compact fluorescent lamps (4-pin). It successfully operates standard 40W models, as well as energy-saving (ES) and rapid start (RS) variants of the 40W twin-tube CFL.

Can this ballast run just a single lamp instead of two?

Yes, the ICN-2TTP40-SC utilizes parallel lamp connection and can safely operate either one or two lamps. Operating a single lamp will not overpower or damage the ballast, but installers should always consult the wiring diagram printed directly on the ballast label for the proper 1-lamp wiring configuration.

Is this ballast compliant with modern energy codes?

Yes, it meets strict NEMA energy-efficiency standards. Additionally, the unit is RoHS compliant (meaning it contains no hazardous materials like PCBs), UL Listed for Class P safety, and CSA Certified for use in both the United States and Canada.
