Acclaim Lighting Unveils Fixture for Museums
Acclaim Lighting has launched the Cylinder One Spectrum, a new fixture designed for applications requiring high-quality white light and dynamic color. The product is aimed at environments like museums that need both precise color rendering and versatile lighting effects from a single luminaire.
- The fixture's Spectrum Five™ light engine combines red, green, blue, amber, and lime LEDs (RGBAL) to allow for a wide tunable white range from 1800K to 8000K. This five-color mixing system provides a more complete spectral output, enabling precise color rendering crucial for museum artifacts while also supporting human-centric lighting designs that can be tuned to influence circadian rhythms. - Its Ai Dim™ feature emulates the "red-shift" of a dimming incandescent source, a behavior where the light warms in color temperature as it fades. This allows designers to create intimate, atmospheric scenes that require a warm, traditional feel, a feature distinct from standard LED dimming which only reduces intensity. - The Cylinder One Spectrum is part of the Acclaim Modular System (AMS), which uses a common housing for different optics and power options. This approach aligns with circular economy principles by prioritizing repairability and upgradability over complete replacement, extending the luminaire's lifecycle. - Control is managed via wired DMX with RDM or the built-in Aria X2™ Wireless system. Aria X2 is a dual-band (2.4GHz and sub-GHz) mesh network technology, offering robust and scalable control for integration into larger building automation systems without extensive new wiring. - The ability to precisely control the spectral power distribution is critical in museum settings to avoid damaging light-sensitive objects while ensuring accurate color perception for visitors. An RGBAL engine offers greater control over the specific wavelengths hitting an object compared to standard tunable white systems. - With a power consumption of 120W and an output of up to 8,610 lumens, the fixture is designed for medium- to long-throw applications, suitable for spaces with high ceilings. The design includes quick-change reflectors for beam angles from 20° to 65°, allowing for on-site adjustments to lighting schemes. - The wide CCT range and color capabilities can be leveraged to meet criteria for standards like the WELL Building Standard, which specifies "Equivalent Melanopic Lux" (EML) to quantify the biological impact of light on occupants. Tunable systems are key to achieving these human-centric lighting certifications.
