Is new technology changing lighting designer's thinking?

For many years lighting design absorbed new technology and simply went about its creative business, because the changes were simply technical improvements that allowed designers to do the same old thing, but a little better than before. This is no longer the case. As advancing technology allows us to broaden our horizons, lighting designers have no excuse not to rip up the rule book and embrace truly inventive design. Lux's applications editor, John Bullock, issues a call to arms.

Why Casambi won and what it means for lighting controls

Casambi won the coveted Controls Product of the Year prize at the 2016 Lux Awards. The little known company triumphed in a field of giants that included, among others, Helvar, eldoLED, Lumenpulse and Osram. Lux's applications editor, John Bullock, considers what it was that gave Casambi the edge and what this means for the future of lighting controls.

Circadian myths busted at LuxLive

Neuroscientist and Lux's Person of the Year Russell Foster led the pioneering team at Oxford University which discovered the eye’s third photosensitive cells, creating a whole new paradigm in interior lighting. The contents of his speech during last week's LuxLive may have taken some in the lighting industry surpise though. Lux's applications editor, John Bullock, reports. 

Value Proposition: V-TAC 45W LED module

Every once in a while, the way that we see the world shifts and the way that we do things needs to be reviewed. The basic approach in commercial lighting, the sector from which so much lighting product derives, is the recessed fluorescent 600x600 modular luminaire. Designed to sit in a conventional suspended ceiling, this is the default lighting option for shops and offices everywhere.

Improved system efficiency in this type of fixture has relied on two things, one in the control of the manufacturer and the other not. The efficiency that the manufacturer has had nothing to do with, but has benefited enormously from, has been the improved light output of fluorescent lamps -  to the general benefit of all users. The improved efficiency that has been less welcome, and which has been fully in the control of the manufacturer, has been the photometric performance of the luminaire.
