Lighting for gallery and museum spaces
This first blog discussing the lighting of gallery and museum spaces deals with the basic issue that we know: that gallery lighting solutions require a sophisticated light performance, but we're not confident that LEDs can provide the answer.
Gallery spaces call for:
the ability of a light source to render colours properly and at the appropriate colour temperature
a lamp + fitting that will enhance the Gallery display by the 'cleanness' of its light distribution
a lamp + fitting that can provide these qualities and offer good energy management
so 'Why LED Lights?'
These have been the issues that have driven the technical specifications of the latest generation of LED lamp, and its these improvements that have resulted in LEDs providing commercial lighting, retail lighting and, increasingly, gallery lighting solutions.
There has been proper scepticism in the gallery and museum sector over LED lighting design and performance – questions around colour rendition quality and over the often outrageous (even if true!) life claims for these new sources. And it's fair to say that many of these doubts were well-founded.
LED design, however, has seen many improvements over and above the retrofit 'LED bulbs' that have been the root cause of many of the doubts that have been voiced over LED performance. But there is far more to the latest generation of LED technology than simply offering replacements to outmoded tungsten halogen reflector lamps.
The very best of the architectural lighting LED is a very different beast. Colour consistency has been proved by the introduction of 'remote phosphor' technology, where the LED chip and the phosphor that creates the white light are two separate components, permitting the LED manufacturer to guarantee a far higher quality of colour performance.
This type of LED is made in a 'cassette' form and has the light fitting designed around it. It means a higher energy efficiency, thermal performance and more secure rated life.
Energy Conservation Tips – How BRIGHT Do You Need It?
Clever presence detectors can tell your lighting control system when there are visitors to a room. If there's no one there, reduce the lighting level. Only use the designed lighting level when there's someone there to appreciate it.
