Did You Know ...
  • Lumens are the level of brightness generated by the overhead's lamp. The higher the level, the greater the colour saturation and image definition., even in large conference settings and lighted rooms.
  • The Post is the metal bar between the base and the lamp unit. A folding post is essential in a portable unit and helpful for proper storage of non-portable units.
  • Two-Lamp Systems allow the presenter to quickly switch to the second lamp if the first lamp burns out during a presentation. For one-lamp systems, a second lamp must be readily available plus you must allow the unit to cool down before replacing the burnt out bulb.
