Lamp Shapes
Straight Lmaps

  • Straight, "L" and "U" Lamps -
    Straight lamps can be almost any length, but are typically limited to the maximum length of standard tubes. "L" lamps and "U" lamps have a single bend.
 U and L Lamps

  • Multiple Bend, Grid Lamps -
    Grid lamps have more than one bend in one or more planes. Electrode legs may be in the same plane, a parallel plane, or at right angles to the plane of the grid.
 Multi Bend Lamps

  • Circular Lamps -
    may be circular or oval in almost any size. The electrode legs may be parallel to the plane of the circle or in a plane at a right angle to the plane of the circle.
 Circular Lamps

  • Interlocking Lamps -
    are for applications requiring redundancy, more than one lamp is used so that the display continues to be illuminated if one lamp fails. The lamps are designed to interlock; i.e., overlap in the same plane to provide optimum uniformity of light.
