IP66 Panel: Sylvania's latest innovation

A luminaire conforming to ISO 14644-1 requirements

The IP66 Panel meets the requirements of clean roomswhere controlling particulate contamination determines the quality of processes and products.

Standard ISO 14644-1 defines air cleanliness classes based on the concentration of suspended particles. The luminaire is advertised as compliant with these classes. 2 to 9covering a wide range of applications, from highly controlled environments to less critical spaces.

"Certified compliant with class 2-9, which means a maximum number of permitted particles ≥ 0,5 μm per m3 of air."

Its design aims to limit areas where contaminants can be retained:

• rounded edges to prevent the accumulation of particles,
• no visible screws making cleaning easier,
• waterproof surface compatible with disinfection protocols.

These characteristics meet the requirements of design offices specializing in controlled environments, particularly in the pharmaceutical or microelectronics sectors.

Waterproofing and resistance: a reinforced technical envelope

The light fixture offers a dual level of protection:

• IP66 on the frontguaranteeing dust and water splash resistance,
• IP50 on the back, suitable for technical suspended ceiling configurations.

It also includes:

• un heat-tempered glass ensuring continuous sealing,
• mechanical resistance IK08, adapted to operational constraints,
• an extended operating range of -20 ° C to +60 ° C.

In terms of implementation, these performance characteristics allow its integration into various environments, including areas subject to frequent washing or thermal variations.

Technical limitation

The IP50 protection on the back requires vigilance when integrating into a technical ceiling, particularly in the presence of uncontrolled airflows or plenum areas exposed to contamination.

Luminous performance and durability in a controlled environment

The IP66 panel boasts a luminous efficacy of up to 107 lm / W, with a lifespan between 30,000 and 50,000 hours.

This data is part of the objectives to reduce energy consumption in commercial and hospital buildings, in line with the requirements of the RE2020 environmental regulations for the overall performance of the equipment.

In the field, this longevity limits maintenance operations in areas where interventions are costly and restrictive (production shutdown, decontamination procedures).

Visual comfort and lighting quality

The light fixture is equipped with a microprismatic diffuserreducing glare with an index UGR < 19This criterion is crucial in environments where visual precision is required.

He also suggests:

• a color temperature 4000 K, standard in a professional environment,
• un IRC > 90guaranteeing accurate color reproduction,
• chromatic homogeneity SDCM < 3.

Available in version ON/OFF or DALI PushIt is integrated into controlled lighting management systems, used by operators to adjust light levels according to usage.

"The micro-prismatic diffuser significantly reduces glare (UGR<19)."

An implementation adaptable to construction systems

The IP66 Panel is available in two formats:

• 600 × 600 mm,
• 1200 × 1200 mm.

It comes with a "Pull-Up" kit allowing for different configurations:

• pose in underside of metal ceiling,
• installation on plaster ceiling,
• version recessed for flush integration.

This type of flexibility meets the constraints of project managers and electrical companies when designing technical ceilings in cleanrooms, where the airtightness of the envelope and the continuity of surfaces are essential.

Application example

In a pharmaceutical production unit, the luminaire can be integrated into a Waterproof modular ceilingin addition to an air handling unit (AHU) providing HEPA filtration. The whole system contributes to maintaining the required ISO class.

An integrated solution within a dedicated range

The IP66 Panel is part of the LiteGuard range, dedicated to controlled environments. It complements the IP65 Panel, which is designed for less restrictive applications.

This range logic allows specifiers and installers to select coherent solutions according to the level of requirement of the project, whether it is a laboratory, an operating room or a sensitive industrial site.

The evolution of this equipment confirms the increasing demands of technical works, where lighting becomes an integral component of the mastery of interior atmospheres and the sanitary quality of the buildings.
