This an interesting article suggesting indirect lighting and daylighting as superior for offices.  I would be interested to see the science, but I think most would agree that this is true by "gut feeling".

The science of how temperature and lighting impacts our productivity

Below is an example of direct/indirect lighting by Prudential Lighting.

Philips Organic LED (OLED), Lumiblade

From the Philips website and coming soon:

More than just another light source

Lumiblade is OLED lighting at Philips. Lumiblade is a large-area diffuse light source. Unlike incandescent bulbs, which generate light by passing electricity through a wire, or fluorescent lamps, which pass current through a gas, OLED lighting works by passing electricity through one or more extremely thin layers of organic semiconductor material.

Now representing: Luminis Lighting

We decided to represent Luminis here in Nashville and it is a welcome addition to my line card.  A recent Product Innovation Award winner, per the Luminis website:

Aramis LED was presented a PIA in the interior lighting category. Designed to last 50,000 hours as a result of an efficient heat dissipating design that ensures low and stable operating temperatures of the LED array, Aramis LED is ideally suited for general illumination of offices, retail stores, schools and multi-purpose spaces where efficiency, reliability and aesthetics are paramount.

Recessed/Surface Gypsum Fixtures

This is a really clean look.  I don't usually recommend seamless-type fixtures as the mudding outward from the ring tends to crack over time and/or the contractor will have a tough time feathering out the plaster to make a smooth transition to the ceiling.  These, however, are made of plaster with the fixture to be recessed at equal depth with the ceiling and only needing a bead of plaster to make the transition.  Neat concept.  Let me know if you would like to see an example of this.

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.
