Recycling rare elements in lamps

A reason for energy efficient lamps being important for resource efficiency and circular economy agendas has much to do with the rare and critical elements found in fluorescent and LED lamps. Rare earths are used on the phosphor coating of lamps to produce soft white light (a well as other colours of light). While rare earths for lighting only account for 7% of the global … Continue reading

Beyond the bulb – servicizing lighting

Big producers like Osram and Philips have indicated a shift in the traditional lighting business towards selling services. But what does servicizing actually mean? This could range from selling services associated with lighting products, to leasing the products, or even paying for only light. Just visit any large lighting producers website and there is already a tab for “services”.  Most are … Continue reading

This is a far cry from the traditional lighting industry model with its focus on the product and power consolidated in the hands  of the big three producers) was so great, that producers … Continue reading

Lighting and the environment – the global perspective

I mentioned in an earlier post about the phase out of inefficient lighting in many countries around the world (shown in the map from UNEP above) and the need to ensure we are recycling and dealing with used lamps in an environmental sound manner (countries with some measures in place are shown in the map from UNEP below). It might be worth … Continue reading

Lighting – what do you know?

When we think of “old” light bulbs we might think of the incandescent developed and commercialized by Swan and Edison in the 1800s.  But do you know the first demonstrated form of electric light was in the form of a gas discharge lamp in 1705? Modern energy-efficient lighting like CFLs and LEDs find their roots in the earlier versions of carbon arc and incandescent lamps. … Continue reading

What’s the big deal with small lamps?

In much of the literature around recycling light bulbs there is mention that many consumers are unaware that they can and should recycle these products when done with them.  Because they are small, it is often easy to just throw them in the rubbish bin. However, like other e-waste light bulbs contain metals, glass, and other materials that can be recycled … Continue reading
