High Efficacy LED Ceiling Panel Lights

SDCM<4 Slimline solution for commercial office areas

The Mackenzie Series LED panel is an efficient, low glare commercial light fitting, designed for use in offices, education, retail, and healthcare facilities.

Low SDCM chip selection ensures luminaires remain a visually consistent colour temperature out of the box, as is particularly advisable for open-plan spaces.

This product can be supplied with a range of accessories including 3hr emergency (remote-test or DALI-Self-Test), wire suspension kits, and is compatible with Kellwood's range of Wireless Pro energy monitoring and emergency reporting wireless lighting controls.

PURPOSE

Though LED ceiling panels are visually hard to differentiate, quality varies dramatically based on components, thermal regulation, build-quality and efficacy.

These elements determine product longevity and energy savings. Kellwood's premium edge lit LED panel family is aimed at high quality facilities where long term gains are as important as the initial capital expenditure.

Build Quality - The frame has white coating finish with electrophoresis technology, this is to minimise risk of scratching the surface. Aluminium back plate is lightweight and suitable for thermal regulation. A silver light reflector and LGP (Light Guide Plate) is used to minimise lumen wastage and to direct light to the desired location. It also uses a polycarbonate diffuser that produces a uniformity of >90% from the light emitting surface.
Thermal Dissipation -The Mackenzie Series has a raised diffuser from the edge lit chips to improve thermal dissipation which will improve the products lifespan and performance.
Chip - Including Samsung 2835 LED chips to produce high lumen efficacy and uses a 2.9V Tridonic driver which extends the products life time.
Sizes Options - It comes in three different sizes: 600x600mm, 1200x300mm, 1200x600mm
DALI dimmable - Available with DALI drivers for integration with compatible control systems to tailor lux levels and minimise running costs.]
Emergency - Remote-Test and DALI-Self-Test emergency packs provide a 3hr maintained emergnecy option.
