Holophane’s HOLOS2 delivers major energy savings

Holophane’s Optimised Lighting Operating System (HOLOS2), combined with the company’s innovative E-capsule Electronic HID dimming ballast highbay in conjunction with Superglass TM, is designed to deliver maximum energy savings in warehouse, retail and sports lighting applications.

With HOLOS2, building operators can optimise control of their HID high or low bay or fluorescent lighting, ensuring that all opportunities to reduce energy wastage are exploited. Field trials have shown that by using the HOLOS2 system with a carefully designed lighting control strategy can reduce energy consumption by as much as 65% compared to the uncontrolled systems that are commonly found in these types of building.

Specialist lighting control software, written specially for high and low bay applications, is coupled with cutting-edge sensing and control equipment to provide a high level of flexibility to meet each project’s requirements and budgets.

Designed for quick, trouble-free installation using a simple two-wire bus system, HOLOS2 enables just one control cable to be used per cable for luminaires, and only one cable for all control devices. Thus it greatly reduces cabling requirements, compared to other systems, reducing both material and labour costs. Further cost savings are achieved by eliminating the need for contactors for on/off switching.

HOLOS2 can be connected using popular containment systems such as trunking or conduit, or by using any manufacturer’s busbar system (e.g. Canalis or similar).

Control options include a light sensor to enable the lighting to be dimmed in relation to daylight levels, a presence detector to dim lighting when zones are unoccupied and time controls to ensure lighting is switched off when not needed.

HOLOS2 also offers scene setting capabilities, allowing building operators to quickly switch between different lighting configurations to suit their needs. For example, in sports facilities there may be different lighting requirements for different levels of competition – or for examinations in a school. Similarly, in a retail environment, the lower lighting levels are required for out-of-hours restocking than when the store is open.
