The Wallace Series LED downlight is designed for commercial applications requiring a budget-friendly luminaire with many of the features of specification-grade downlights.
Available in a range of outputs from 1,000lm to 2,730lm and housings to suit most common cut-out sizes, the Wallace Series a flexible solution for most retrofit and new-build projects.
3hr Emergency (remote-test or DALI self-test) mitigate the need or cost of additional non-maintained emergency fittings, while dimmable driver options (1-10V, DALI and Main-Dimming) can be supplied to allow simple integration into compatible lighting controls.
Where stylistic designs are appreciated, bespoke bezel colours can be offered to compliment internal and external architecture.

LIGHT DISTRIBUTION OPTIONS
Polar: solid green C0–C180, dashed blue C90–C270, dotted amber the plane through the brightest direction when it lies between them; rings at 25% steps of the peak. Isolux: the footprint on the floor with the fitting aimed straight down, contours at 50%, 25% and 10% of the brightest point, grid in mounting heights (H). Both are drawn from the first measured file for that optic.
DESIGN FEATURES
Downlights designed for PURPOSE
The Wallace Series LED downlight is assembled with premium components including Epistar 2835 & 5630 LED chips. Ideal for those that are looking for a functional, high quality but budget-conscious downlight. Glare: The Wallace series is designed with reduce glare in mind.

Lumen Maintenance: Premium components and patented heat sink design system prolongs luminaire lifespan to L70B50 >50,000 hours. Emergency: 3 hour maintained emergency kit or pack with DALI self-test or remote testing. Supplied with LiFePO4 batteries, providing double the lifespan of conventional NiCd batteries, and very low self discharge and power consumption under use. Flexibilty for Retrofit and New-Build: 11W - 30W models are available in a range of housings diameters, designed to fit common cut-outs from 90mm to 200mm. Bespoke Colours: the front bezel can be surface-finished to a bespoke colour - commercial viability subject to order quantity.
