FULHAM
Frequently asked questions
Common questions about FULHAM from 3G Electric.
What input voltages do FULHAM ballasts support?
FULHAM electronic fluorescent ballasts are available in universal input voltage configurations of 120 to 277V AC, as well as fixed 277V AC models. The universal voltage ballasts can operate on any voltage within that range without manual adjustment, simplifying installation across different electrical systems. The emergency LED drivers also accept 120/277V AC input.
What lamp types are compatible with FULHAM ballasts?
FULHAM ballasts support a range of linear fluorescent lamps including T5, T8, and T5HO types, as well as compact fluorescent lamps (CFLs). Specific models are designed for lamps such as FT50, F58T8, and T5CR40. Always verify the lamp type and wattage against the ballast's specifications to ensure compatibility.
How many lamps can a single FULHAM ballast drive?
FULHAM ballasts are available in configurations that support 1, 2, 3, or 4 lamps, depending on the model. For example, the RHA-UNV-254-LT5 supports 1 or 2 FT50 lamps, while the WH6-277-L supports up to 4 lamps. Check the product datasheet for the exact number of lamps supported.
What is the battery type used in FULHAM emergency LED drivers?
FULHAM emergency LED drivers use nickel-cadmium (NiCd) batteries. These batteries are commonly employed in emergency lighting due to their reliability and ability to deliver consistent power during outages. The drivers are designed to provide backup illumination for a specified duration, typically 90 minutes, as required by code.
What lumen outputs are available for FULHAM emergency LED drivers?
FULHAM emergency LED drivers are offered in lumen outputs of 500, 750, 1,000, and 1,250 lumens. The specific output depends on the model, with linear configurations typically providing 500 lumens and H-configuration models offering higher outputs up to 1,250 lumens. These drivers are intended for use with LED arrays in retrofit kits.
Are FULHAM ballasts suitable for retrofit applications?
Yes, FULHAM ballasts are commonly used in retrofit projects where existing fluorescent fixtures are upgraded or replaced. The universal voltage range and multi-lamp support make them adaptable to various fixture types. The emergency LED drivers are specifically designed for LED array retrofits, providing emergency backup in a compact form factor.
