Your billboard company is starting to lose business with Hollywood clients who want their movie promotions well-illuminated at night. The metal halide up-lights on your signs are starting to flicker, creating an ugly yellow glow on the lead actress' teeth. The good news is your up-lights are fine, just get the 39-watt e-ARC Keeper HID emergency ballast from Philips Bodine.
This eAK39 uses a nickel-cadmium battery to support your metal halide bulb during intermittent fluctuations in the line voltage. Since the electronic arc (which generates the MH bulbs powerful glow) will go dead within a second after a power loss, the e-Arc Keeper keeps the fire going. Now the lead actress in your client's upcoming film won't look like she has rotting teeth!

The e-AK arc keeper continues the electrical flow to the lamp, giving your emergency backup generator time to come online and warm up. This "intelligent" ballast will regulate itself and switch to DC mode automatically using an inverter component. A test/monitor wall switch is included so you can test the Ark Keepers readiness at any time without a ladder.
Make sure to select the proper voltage (120 or 277v) at checkout or when calling our support team.
This arc maintenance battery pack has mounting feet on each end for simple attachment inside the metal halide fixture or remote transformer box. Its thin F-Can design will fit in most track lights and HID down lights, and the steel casing is finished with an white powder coat which prevents corrosion.
