COLOUR
Many designers also harbour concerns about the quality of LED lights, especially when it comes to colour. The two chief criticisms are temperature, as LEDs tend to be bluer than halogen lights, and colour rendering (the accuracy of colour).
Stephen Cannon-Brookes, of Cannon-Brookes Lighting & Design, says that while LED lights can have the same levels of colour quality as halogen lights, this is complicated by the fact that manufacturers have introduced technology to achieve a better quality – but at the expense of efficiency.Lighting Science Group, which has manufacturing operations at the site of <a href="http://www.zclp.com/">Book scanner</a> its headquarters in Satellite Beach, Florida, said its new LED bulb is completely recyclable and contains no mercury.
“The irony is that lights with lower colour quality tend to have higher efficiency – so by making the light source look warmer (converting blue light into red) you actually make it less energy efficient and hotter,” saIn addition to LED lighting products, Chicony Power also has power supply <a href="http://www.chililighting.com/">LED bulb</a> orders from US-based game console vendors and is currently contributing 36% of the Chicony Group's revenues with chance to be listed on Taiwanys Cannon-Brookes.Now, in the <a href="http://www.fjever.com/">Insulator</a> second phase, KMC plans to introduce LED on Bidhan Sarani, Vivekananda Road, Amherst Street, Loudon Street, Camac Street, Bondel Road, Ballygunge Circular Road, Gurusaday Road and Alipore Road. “So it becomes a pay off between colour quality and efficiency.”
This places museum in a dilemma – should they opt for quality or compromise for energy savings?
Cannon-Brookes says the answer depends on what objects a museum houses and what its overriding mission is. “Colour is very important for collections such as paintings, which suggests colour rendering should be the priority. To date,The new LED bulbs screw into any standard E26/E27 base. That translates into major savings <a href="http://www.generallamp.com/sitemap.html">led downlights</a> on electricity bills as well as a dramatically reduced carbon footprint. that means halogen lighting.”
Manufacturers tend to agree that museums that place colour rendering above everything else will probably be more satisfied with halogAfter the success of a pilot <a href="http://www.sfyh.com/inflatable-seat_ss">inflatable seat</a> project to light up the city's streets with the latest LED technology, the civic bosses now want to install LED lights across Kolkataen lighting. However, Chris Tiernan, managing director of ERCO Lighting, says that the rising number of art galleries and museum installing LEDs suggests that colour quality is already at an acceptable level.
