LIGHTING
Three birds with one SLT
Beyond the obvious economical considerations discussed, having an
entire building exterior operate automatically affords a few additional
bonuses, one of which is within the realms of aesthetics. Instead of a
building’s façade being a hodge-podge of open and shut blinds, an
automated system gives a clean and neat appearance of aesthetic
uniformity. An extra perk. Our third bird is the one of external illumi-
nation: Having this integrated controllers present nearby every few
motorised blinds on a building’s façade has an extra upshot: fully,
detailed control infrastructure for the layout of external LED illumina-
tion of a building’s façade.
Conclusion
It has become quite popular to illuminate a building’s façade with
layouts of LED lighting, allowing the creation of intricate patterns,
Shining brightly after 50 years of innovation
Celebrating its 50th anniversary this year,
Nordland Lighting is continuing its strong
tradition of local innovation by launching
its first Zone 2 LED luminaires for mining,
oil and gas and petrochemical applications.
The industrial and hazardous lighting
specialist is also making these new lumi-
naires available in stainless steel for spe-
cific requirements, in addition to launching
die-cast aluminium bulkhead Zone 2 LED
luminaires.
“There is a definite move towards LED
technology in industrial and hazardous
lighting, due mainly to the cost-saving
and increased safety benefits,” Nordland
Lighting Engineering Manager Eben Fer-
reira comments.“There has been a dramatic
decrease in the cost of LEDs, which means
it is better to invest in the latest technol-
ogy than in cold cathode fluorescent lamp
(CCFL) systems, which are anticipated to
be phased out completely over the next
ten to 15 years,” Ferreira explains. Com-
menting on what gives Nordland Lighting
the leading edge, Sales Manager
Johann Lamprecht comments: “We
offer good reliable products with an
affordable pricing structure.We look
after our customers’ needs, ensuring
we supply the best suitable product
for their direct requirements, all
in a highly competitive market.”
The manufacturer also has a dedicated
lighting-design team, including a qualified
Lighting Practitioner accredited by the Il-
lumination Engineering Society of South
Africa (IESSA). Nordland Lighting also
offers an applications engineering service.

or at times even shapes and text. Utilising the SLT’s wiring layout
provides a built-in infrastructure for the control layout of such LED
lighting, eliminating the need of extra wiring and installations.

take note
• Double-skin glass facades entail shade systems which
require control.
• The SLT controller, developed by Control Applications, uses
a unique control algorithm, providing optimal aperture for
window-blinds and infrastructure for LED lighting control.
• This optimal aperture provides energy efficiency and
aesthetics.
