Robertson PSB296T12HOMV Ballast Overview
The Robertson PSB296T12HOMV ballast supports 1 or 2 F96T12/HO lamps, including F96T12/HO and related sizes (F72T12/HO, F60T12/HO, F48T12/HO). Designed for 8-foot commercial and industrial lighting, it offers internal surge protection, end-of-lamp-life protection, and thermal protection for safe operation across temperatures. It is UL Listed and CSA Certified, meeting ANSI C82.11 and C62.41 standards, with a high power factor (>0.98) and low THD (<10%). Programmed Start ignition reduces wear on lamps in frequent on/off cycles.
Features include: Programmed Start, high efficiency, quiet operation (Sound Rated A), and energy-conscious design. This ballast is positioned for environments with occupancy sensors and steady duty cycles where lamp longevity matters.
Advance RS-110-TP High Output Ballast
The RS-110-TP is a high-output magnetic ballast designed for T12 fluorescent lighting, specifically F96T12HO lamps. This model provides reliable performance for a range of commercial and industrial applications, making it suitable for retrofits or new builds requiring robust high-intensity lighting. The ballast is engineered for compatibility with standard T12 configurations and is known for durable operation in demanding environments.
Key considerations include compatibility with T12 HO lamps, retrofit viability, and long-term reliability. Magnetic ballasts like the RS-110-TP are often preferred where simple operation and low maintenance are priorities, though energy efficiency comparisons with electronic ballasts should be considered in total lighting design.
GE 74472 T12 Fluorescent Ballast
GE 74472 is an electronic ballast designed as a replacement for magnetic T12 ballasts, offering quieter operation. It provides up to 20% energy savings versus standard magnetic ballasts and is compatible with standard wiring and mounting requirements. This model supports both standard and energy-saving lamps, as well as two-lamp or one-lamp installations, delivering versatile performance for maintenance or retrofits.
Considerations include energy savings, reduced noise, and installation compatibility. Electronic ballasts like the GE 74472 can improve efficiency in facilities seeking modernization while maintaining existing fixture layouts.
OHLECTRIC Keystone KTEB-220-1-TP-EMI
OHLECTRIC’s replacement ballast for Keystone KTEB-220-1-TP-EMI provides 2-lamp T12 electronic ballast operation at 120V input with Instant Start, and an EMI/UL-Approved design. It offers a ballast factor around 0.88, contributing to measurable energy savings. The unit emphasizes efficient, flicker-free operation with rapid start capabilities suitable for environments with frequent on/off cycling or occupancy-based controls.
Considerations include ballast factor, instant-start performance, and UL/EMI compliance. This option is well-suited for facilities seeking steady performance across varying temperatures and loads while maintaining user comfort.
Philips Advance RELB-2S40-N
The Philips Advance RELB-2S40-N is an electronic ballast for T12 lamps operating at 120/277V. As a commercial-grade Philips Advance product, it provides reliable performance and compatibility with a variety of T12 HO configurations. The RELB-2S40-N is designed for energy efficiency and steady startup, aligning with modern facility requirements for reduced energy use and consistent lighting quality.
Key considerations include voltage compatibility, lamp type support, and brand reliability. Philips Advance products typically emphasize long-term support and integration with existing electrical ecosystems in commercial buildings.
Buying Guide: Key Purchase Considerations
- Lamp type and compatibility: Ensure the ballast supports the exact T12 HO lamp sizes you use (e.g., F96T12/HO, F72T12/HO, etc.).
- Start method: Programmed Start helps extend lamp life in occupancy sensors or frequent on/off cycles; Instant Start can be preferred for rapid ignition in busy environments.
- Electrical characteristics: Check ballast factor, THD, and power factor. Higher power factor and lower THD improve energy efficiency and reduce electrical stress.
- Voltage range: Match ballast voltage ranges (120V, 277V, or dual 120/277V) to your supply and fixtures.
- Physical fit and mounting: Confirm mounting, wiring, and fixture compatibility with your existing housings and enclosures.
- Certification and safety: Look for UL Listed, CSA Certified, and EMI/RFI compliance to ensure safety and regulatory alignment.
- Maintenance and serviceability: Prefer ballasts from reputable brands with local technical support and clear warranty terms.
- Energy efficiency goals: Electronic ballasts often reduce energy use compared with magnetic equivalents; however, consider total system design and fixture efficiency.
- Noise and thermal performance: Sound ratings and thermal protection contribute to long-term reliability in occupied or sensitive spaces.
- Upgrade strategy: If retrofitting, assess compatibility with existing fixtures and potential need for wire reconfigurations or fixture upgrades.
