Product Highlights

  • Ignites up to two T-8/T9/T10/T12/T8HO/T12HO lamps

Philips Bodine B50LP low profile fluorescent emergency ballast works in conjunction with aa low-profile or standard AC ballast to convert new or existing fluorescent fixtures into emergency lighting. The emergency ballast consists of a nickel-cadmium battery, charger and electronic circuitry in one case. When AC power fails, the B50LP immediately switches to the emergency mode, operating either one or two lamps at a reduced lumen output for a minimum of 90 minutes. When AC power is restored, the emergency ballast automatically returns to the charging mode and delays AC ballast operation for approximately three seconds to prevent false tripping of the AC ballast end-of-lamp life shutdown circuits. 

  • Can be used with most 17-215 watt, 2'-8' T8, T9, T10 or T12 fluorescent lamps without integral starters, including Ubent, HO, VHO, circline and energy saving fluorescent lamps. Also compatible with most one, two, three and four lamp electronic, standard, energy saving and dimming AC ballasts. 
  • Can be used with either switched or unswitched fixtures
  • Produces 750-1300 lumens of initial emergency light output, depending on the number of lamps (one or two), wattage and type of lamps
  • Suitable for indoor and damp locations and for sealed and gasketed fixtures, including fixtures rated for wet locations

Ballast Type
Magnetic ballasts are a legacy technology and use inductance to transform the line voltage to the voltage required to "fire" or excite the gasses in a lamp. Electronic ballasts use a variety of starting methods, and are more efficient than magnetic ballasts in converting input power to the proper lamp power and operate fluorescent lamps at higher frequencies, resulting in an overall lamp-ballast system – increasing efficacy 15% to 20% over a magnetic equivalent.
Length (in)
Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.
Width (in)
For fixtures and ballasts, width is the measurement of the total horizontal distance from left to right of the product in inches.
Height (in)
For ballasts and fixtures, height is the measurement of total vertical distance from the top of the product to the bottom expressed in inches.
