Explainer: LED panels can ruin fire rating of ceilings

We have seen yet more lurid headlines in the press, reporting that hospital projects built under Private Finance Initiative (PFI) contracts have been condemned as unsafe following inspections of fire protection measures. The stories are being spun as a stick to beat the PFI programme with, but there is a very real issue here for the lighting specifier, contractor and manufacturer.

New York's bridges to get multi-million dollar LED facelift

New York's bridges to get multi-million dollar LED facelift

New York City's iconic Hudson River bridges are set to undergo an LED make-over, in a move that mirrors London's 'Illuminated River' project to revolutionise its own river-scape.

Nine New York bridges will receive an LED overhaul during the first phase of the $500 million project, ranging from the Henry Hudson Bridge in the Bronx to the Crossbay Veterans Memorial Bridge in the Rockaways.

Meet the streetlights that are powered by footsteps

A new street lighting system that harnesses energy from pedestrians’ footsteps has been installed in Las Vegas in the United States.

The foot-powered fixtures were developed by EngoPlanet, a New York based start-up. The street lights are part-powered by kinetic energy generated by footsteps, which is absorbed by tiles installed in the pavement. Solar panels are also used to boost energy levels when necessary.

Could LED insect discovery help to beat Zika and malaria?

Could LED insect discovery help to beat Zika and malaria?

A study completed by academics at Bristol University has found that LEDs attract significantly less insects than other light sources. The discovery could be beneficial to nations in South America and Africa, which are fighting mosquito-borne diseases.

The researchers considered a number of different light sources ranging from a tungsten filament lamp to fluorescent light sources and white LEDs and concluded that the heat emitted by light sources has more of an effect on insect attraction than the colour of the light.

London bridges plan in troubled water as critics pan ideas

The lighting schemes unveiled as part of the Illuminated River design competition to illuminate central London's river bridges have received a frosty response from lighting designers. The submissions, which include proposals to link each bridge with lasers of light, were slammed as ‘impractical’ online. It was also noted by designers that the project will only add further to London’s light pollution problem.

A set of radical lighting schemes have been unveiled as part of the Illuminated River design competition to illuminate central London's river bridges. The submissions, produced by a number of international designers, include proposals to link each bridge with lasers of light, bathe London Bridge in a fiery hue and plant retro light posts in the waters of the river itself.
