The Marshall 2 Series is a versatile range of LED panel luminaires. Designed primarily for recessed applications, these panels are particularly well suited for multi-storey office, educational, and healthcare environments where a high consistency of colour temperature and enhanced TP(a) fire rating is preferable.

The aluminium 595x595mm frame is manufactured to suit 600x600 grid-suspended ceilings and finished in white. The Marshall 2 Series delivers a uniform, low-glare lighting solution.

Available with DALI dimmable drivers, and DALI self-test 3 hour emergency, these panels are compatible with Kellwood Lighting's Wireless Pro lighting controls, offering further operational savings via localised dimming, energy monitoring, and emergency reporting,

DESIGN FEATURES

Panel lights designed for Purpose

The Marshall Series panels are primarily designed to meet the strict specification requirements associated with enterprise-grade projects. Design features include: Fire Rating - the TP(a) fire-rated diffuser, slows potential fire-spread through suspended ceilings, and on to other areas or floors of a building, enhancing the safety of occupants throughout. Colour Consistency - a small colour tolerance of MacAdam 4, maximises visual colour consistency between luminaires. This is particularly beneficial in large open-plan spaces where luminaires are easily comparable. 3000K, 4000K, and 6500K - Available in a variety of colour temperatures to suit the warmer light associated with healthcare and education and higher CCT sometimes associated with manufacturing. UGR<19 - The micro-prismatic diffuser reduces glare, when compared to early generation LED panels. Emergency - Remote-Test and DALI-Self-Test emergency packs provide a 3hr maintained emergency option. DALI dimmable - Available with DALI drivers for integration with compatible control systems to tailor lux levels and minimise running costs.
