If a lighting ballast fails, do you change it out hot? That's a fairly common practice, but you can get electrocuted by 277V just as surely as from a higher voltage. If you're on a ladder, the fall ...

International Rectifier has introduced a new control ic for magnetic ballasts used in fluorescent lamps. The IRS2538DS emulates the behavior of a magnetic ballast control system, leveraging IR's ...

Lighting can be a large part of any building's electrical load — 30% or more if it is heated by non-electrical means. As an energy cost-cutting measure, consider upgrading your lamps from incandescent ...

A reliable, efficient control IC for magnetic ballasts used in fluorescent lamp, the IRS2538DS, emulates the behavior of a magnetic ballast control system. The IC leverages IR's patented ballast and ...

In part 1 we discussed rectifying the ballast AC current to DC and we showed an open load protection circuit. Direct replacement of fluorescent tubes with LED assemblies can lead to uneven lighting.
