“We recommend that Reeflux bulbs should be run with electronic metal halide ballasts or pulse start magnetic ballasts. Probe start magnetic ballasts will not fire Reeflux lamps properly, which could lead to difficulties with the bulbs. The Reeflux lamps are pulse start. Probe start ballasts may ignite the lamp, however the drawbacks are shorter life, color variation between lamps, a shift in color over time, and low efficiency. Our Reeflux lamps require an ignitor to fire throughout its life cycle.”
