Museums should

Museums should also do their research to ensure they understand the system efficiency before they buy. “Most manufacturers tend to avoid quoting the system efficiency – the actual amount of light produced - and instead quote the output in laboratory conditions,” Cannon-Brookes explains.

Investing in upgradable systems is also important.Lighting Science Group, which has manufacturing operations at the site of Book scanner its headquarters in Satellite Beach, Florida, said its new LED bulb is completely recyclable and contains no mercury. Jean-Francois Hocquard, chief executive of light designer Luxam, is concerned that the LEDs being sold today might not exist in, say, 10 years' time.In addition to LED lighting products, Chicony Power also has power supply LED bulb orders from US-based game console vendors and is currently contributing 36% of the Chicony Group's revenues with chance to be listed on Taiwan Despite their long shelf-life, the systems will need replacing eventually and Hocquard’s concern is that museums may find they have to pay for another complete upgrade. He adds: “Museums might also have to replace display cases, depending on how the lighting has been installed. The important thing to keep in mind when investing in lighting is that it is upgradable.”

So, should museums jump on the LED bandwagon now or wait until the technology improves further or the cost comes down?

“I would advise museums to proceed with caution,” says Cannon-Brookes. “LED technology has increased very quickly but has still not reached the plateau that we are familiar with for tungsten halogen lighting.After the success of a pilot inflatable seat project to light up the city's streets with the latest LED technology, the civic bosses now want to install LED lights across Kolkata”

But Nick Wraith, managing director of LED lighting manufacturer Luminal, says that, while technology will continue to improve,The new LED bulbs screw into any standard E26/E27 base. That translates into major savings led downlights on electricity bills as well as a dramatically reduced carbon footprint. museums that wait for this will miss out on the potential energy and cost savings over that period.For the second time in solar panel the four-year history of the NHL Winter Classic, the Penguins are one of the participating teams for the New Year's Day game. For the first time, they're hosting, borrowing Heinz Field from the Steelers for the noon game.
