A LIGHTING EVENT CROSSING THE GLOBE ON 14 NOVEMBER 2013
The International Association of Lighting Designers (IALD) will “Chase the Dark” across the globe with a series of guerilla lighting installations, demonstrating the power of light in urban communities, on 14 November 2013. acdc LED Ltd. is the global sponsor for this event, and will provide the lighting equipment for each city.
“IALD’s Chase the Dark is an opportunity for lighting enthusiasts around the world to share their creativity with the public,” said Kevin Theobald, IALD President 2012 + 2013 and Associate Director at GIA Equation in London, UK. “But it’s also a chance for us to unite IALD’s many local communities around the globe in one activity that emphasizes and champions the power of light in human life.”
IALD architectural lighting designers from eight counties spanning eight time zones will take part in this global event. Each host city will invite participants to shape an urban environment with light, creating several miniature lit scenarios over several hours. These displays will be installed for just a matter of moments - the images of each light project will be captured permanently on camera and shared on Twitter using the hashtag #IALDchasedark all evening long.

In August, Philips issued a voluntary recall of certain of its Endura 12W A19 and Ambient 12.5W A19 LED dimmable lamps. The lamps in question were isolated to a global batch of 99,000 that were produced in November 2012.
Lamp recalls in the lighting industry are nothing new. As two recent LED lamp recalls show, technology hiccups are to be expected and manufacturers are taking the responsible steps to address the issue.
Philips has three A19-style LED replacement lamps on the market. The lamps in question have a yellow cap and have since been replaced with a white-capped version as the company moves away from remote phosphor technology. Full details for this recall can be found on the U.S. Consumer Product Safety Commission’s website as well as Philips’ website.
Lamp recalls are nothing new. In March, Lighting Science Group issued a recall of 554,000 6W, 8W, and 9W A19, G25, and R20/PAR20 lamps that had been sold under the brand names Definity (Lighting Science Group brand), EcoSmart (Home Depot brand), Sylvania, and Westinghouse, the hazard being possible overheating leading to fire.

The lighting industry has its eyes on California in terms of energy legislation. On January 2010, California Title 20 requirements for portable fixture went to effect. It offers five options for compliance with two exceptions: wall mounted swing-arms fixtures can be sold without a bulb-in-the-box requirement, but the lamp is limited to 57W through 2011, and 43W after that. Single Socket picture lights have a maximum wattage of 25W. With multiple sockets, the maximum allowed dips to 15W.
- 1. The “bulb-in-a-box” fixtures require that manufactures include a compact fluorescent lamp in the product packaging so that a standard screw-based socket can continue to be used, but the bulb has to be energy efficient.
- 2. A portable fixture will come with a fluorescent bulb resulting in a fluorescent portable lamp.
- 3. A portable fixture will be manufacture with a new kind of socket GU24 with cannot be used with incandescent lamps only with compact fluorescent.
- 4. Equipping the portable lamp with an LED light engine that plugs in screws in or self-contained and meets certain efficiency requirements.
- 5. Portable lamps can be equipped with a single-ended, non-screw based halogen lamp socket. This can be a standard or low voltage light source, but the fixture must have a dimmer or high/low control and the maximum wattage allowed is 100W.
