How Many Lights – Standards AS/NZS  1680.1:2006

The How Many Lights website is a very useful source of information on the “Recommended maintained luminance” for the activity/interior.

For example a value of 40 Lux is recommended for areas “with Interiors rarely visited with visual tasks limited to movement and orientation” such as corridors or walkways.

A value of 1600 Lux is recommended for areas that are “Exceptionally difficult ” such as Finished fabric inspection; assembly of minute mechanisms, jewellery and watchmaking.
There is also a table recommending the Watts/Square metre

AS/NZS 4243.2:2007 Table 1

Cafeteria, fast food outlet = 8 W/m2
Warehouse = 8 W/m2
Hotel = 10 W/m2

Office space = 12 W/m2
Supermarket, shopping mall = 16 W/m2
Laboratory = 17 W/m2
Workshop = 18 W/m2

What is the best LED bulb?

Philips provide high quality LED bulbs at a very good price.
CRI 90. This is a Colour Rendering Index of 90 enabling true Natural Colour. CRI 90 is a very recent step-up in technology for the replacement of old incandescent bulbs. Other low-cost bulbs with a CRI 80 provide poor quality colour rendering (washed-out lack of colour reproduction) therefore are only suitable for general area lighting. CRI 90 with Philips Interlaced Optics Technology provides a viable replacement for the incandescent lightbulb. This is a low-cost non-dimmable LED bulb. Plilips also have a range of dimmable LED bulbs.

What is Philips Interlaced Optics Technology?

Philips Interlaced Optics Technology produces 40% less glare for comfortable soft lighting.
This feature provides very good light for reading under the bulb. It also reduces glare by providing a soft light when the bulb is viewed from across the room. I was able to use a lower wattage bulb as it provided comfortable reading and reduced glare when looking past the downlight. This non-dimmable bulb with a CRI 90 and Philips Interlaced Optics Technology provides a high quality low-cost replacement for incandescent bulbs.
