The Holophane HMS Lowering Device System is designed for lighting in large areas such as roadways, port facilities, airports, water treatment plants, parking lots, rail yards and storage areas.
Choice of Luminaires: HMST, HMSD, HMSP, HMSC, Mongoose, Prismbeam or Predator luminaires may be clustered on the lowering device mounting ring in various combinations to provide customized lighting solutions.

Choice of Systems: Holophane provides many options in choosing a lowering device system. Top latching systems provide a high level of safety for personnel, equipment and public areas. Top latching also provides long life to the system by removing all weight from the raising and lowering components. Bottom latching systems are also available.

Additional system choices include self centering luminaire ring or non-centering ring, winch mounted in the pole and portable drive motor or motor mounted in the pole. Optional accessories include lighting protection, obstruction lighting and multiple circuit wiring.
