Haitz's Law and 200 Lumen/Watt Cree LEDs

Cree has released an LED with 200+ Lumens/Watt. 

 Haitz Law Wiki

"every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light."

XLamp Link to Cree

Built on Cree’s revolutionary SC³ Technology™ LED platform, the MK-R LED delivers up to 200 lumens-per-watt, enabling lighting manufacturers to create the next generation of high-lumen indoor and outdoor LED lighting systems. MK-R LEDs are available in EasyWhite® color temperatures, providing the LED industry’s best color consistency for designs that use only one LED. For systems that use multiple LEDs, MK-R enables manufacturers to use fewer LEDs while still maintaining light output and quality, which translates to lower system cost.

Plastic Light Bulbs !!??

"

US researchers say they have developed a new type of lighting that could replace fluorescent bulbs.

The new source is made from layers of plastic and is said to be more efficient while producing a better quality of flicker-free light.

Prudential Lighting

I was at the Prudential Lighting factory Friday of last week and was impressed by a couple of their products/capabilities.   The first photo below is of an 18" recessed round with mud ring for trimless application and linear recessed with a mud ring on one side to accommodate drywall installation and typical flanged on the other side to move to a lay-in ceiling.  Neat application that may be desirable for lighting over conference tables for example.  The second photo is of a 6' round recessed, certainly a statement.

Color Kinetics on the Empire State Builiding

One of my Philips manufacturers, Color Kinetics, launched the re-lighting of the Empire State Building in LEDs with intro by Alicia Keys.  Pretty neat. 

Locally, you can see Color Kinetics changing colors at the Nabrico Building by the stadium.  The colors can change in rapid succession or fade over a long period of time.  As is often the case with LEDs, maintenance costs and energy costs will be significantly reduced.  I have a large sampling of CK fixtures and can do simple examples and mock-ups if anyone would like to experiment or show a client. 

Thanks and please find a video in the following link.

This is the featured project on the Sistemalux website.  I worked with Hawkins Partners on this one.  Let me know if you would like to learn more about the lighting design or the fixtures.

At 755 feet high, Heron Tower, designed by Kohn Pedersen Fox, is the tallest building in the City of London. To highlight the building's prominence at night, a striking approach to its illumination was adopted by Illuminating Concepts, an American lighting design firm based in Farmington Hills, Michigan. Traditionally, floodlighting such a building would have involved copious amounts of “HID” (High Intensity Discharge) projectors either located remotely from the building and aimed onto it, or located on the façade with fixing systems. These traditional methods consume high levels of energy, and require regular maintenance schedules, which is not an easy task when trying to access luminaires mounted hundreds of feet from the ground on the façade of a building. New LED lighting technology allows us to change radically the way in which we design lighting schemes for modern architecture. Instead of lighting the building we can integrate the lighting into the façade therefore creating a completely different visual perspective of the building at night.

This is the design philosophy undertaken for the external lighting on Heron Tower. The structure framing the building façades creates a grid like pattern onto which individual point source blue LEDs were fixed, punctuating the intersecting points of the building's structure. Illuminating Concepts specified 750 units of iGuzzini's Glim Cube, surface mounted 1 watt fittings for the application. Emitting a blue light, the organized array of Glim Cube luminaires act as finery for this 46 storey jewel within the heart of the city. The visual impact is both dramatic and striking, giving Heron Tower its unique identity and appearance in the City Of London at night. Also of significant importance, this lighting scheme is almost maintenance free and consumes very little energy (less than 1 kw/h), which is in line with Heron Tower's focus on sustainability (the building has a BREEAM rating of ‘Excellent' and incorporates a number of green initiatives including an offset core that prevents solar heat gain and a veil of photovotaic cells on the southern façade). The LED light fixtures have a rated life of 50,000 hours which equates to over 13 years of use with the lighting being switched on for an average of 10 hours every night of the year.
