The Hong Kong Science Museum has upgraded its exhibit lighting to a light emitting diode (LED) system from Altman Lighting in order to give the museum a more theatrical atmosphere.
Supplied from Pacific Lighting Ltd., the museum wanted to move to LEDs in order to save energy costs, improve efficiency and reduce maintenance costs. Pacific Lighting installed mains dimmable and DMX controlled luminaires that replicate the soft light output that is expected from a theatrical or studio Fresnel. At 150W, the Pegasus lighting from Altman meets the output of its 750 watt incandescent counterparts and is available in four different color temperatures.
The Hong Kong Science Museum features more than 500 exhibits in an area that spans more than 65,000 square meters. Recently, the museum opened a series of new exhibits designed to encourage a greater understanding of the world.
“When looking at our choices for the fixtures in the design, we had to keep in mind the physical size, light output, beam spread, fixture control, and of course cost,” says Hugh Chinnick, director and project lighting designer at Pacific Lighting. “Since the museum already has a flexible grid system with distributed dimming and DMX outlets, the challenge really became how to effectively amplify the theatrical environment once all the set pieces and exhibitions elements were in place.”
Other lighting used included the Spectra Cyc systems that blends colors to reduce direct-view pixilation while the on-board power supply allows for direct power and data inputs. Individual units can be linked side-by-side for greater saturation of light. The lighting system comes with a library of pre-programmed single colors to match various color mixes.
The Hong Kong Science Museum also took use of Altman’s ME4 ellipsoidal LED framing projector to give crisp patterns or graphic projections to the exhibits.
The result was LED lighting fixtures hanging in the new exhibitions, including Mangrove Forest, Forest Trail, Woodlands Diorama, Sunrise in the Savana Diorama and the Sandy Beach Diorama.
