Recent LED-technology advances: the new Durabulb and L-Bar light sources

For a number of years, the lighting industry has directed its efforts to innovate LED lighting sources and have made these widely accessible.  As a result, brighter options for sources of light and for varied temperature colors have become available, and, with the advantage of an extended life cycle, LED’s have turned to be a selected option for homeowners.

The Lighting Science Lab launched earlier this year two products that continue their sustainable and health centered approach to lighting:

  • A lightweight ideal for commercial application, the L-Bar, is a linear luminaire with 100º degree beam angle, and an output of up to 4,500 lumens, powerful enough to replace traditional fluorescents.
  • The Durabulb, an innovative LED that “resists breakage due to impact, vibration and external stresses”, it is made of recycled materials and it doesn’t require packaging, so less waste is involved in the process.

Both products are developed as part of the LS Earth project, a line manufactured around sustainability, health, and, an ecological approach to packaging and disposable materials.



Lighting & Layering: shades and texture variations to experience environments built for life

Natural light is both physically and psychologically rewarding to people, contributing to our health, productivity and wellbeing, at home, work, or school.

In a built environment, thresholds, portals, doors, bridges and windows, are transitional spaces, providing access from one area to another. From a biophilic design perspective, these areas provide a connection to the exterior, important passageways to the surroundings, often fostering a sense of comfort.

An effective design occurs in complementary relation to this idea of connection to nature and feelings of shelter and protected refuges. Bring the natural and the built environment as complementary within open areas to recreate an element of spaciousness. There is a visual hierarchy of textures, colors, materials, shapes, decorative objects, all elements competing for attention, and light is a powerful medium to establish the most adequate setting to a scene.

Our visual system is naturally drawn to the brightest objects in our field of view. Focus can be created not just with increased light levels, but with changes in the direction or color of light. From minimally decorated architectural spaces to highly contrasted objects within a lighting scheme, layering should recreate three-dimensional depth, a factor of daylight exposure.

  • Downlights, a narrow-beam from above to create a glow of reflected light.
  • Low-level light, a floating effect to soften, for instance, an evening setting. Warm white LED strips can be used to achieve this effect.
  • Task lighting provides a pool of light that is bright enough to read by, originated from table or floor standing lamps.
  • Side lighting, provides good contrast for small objects. Ideally, it injects infill and removes shadows.
  • Concealed lighting, within boxing for linear displays, under kitchen cabinets, in shelving units, or cove ceilings to highlight unusual architectural details; these luminaires create a diffuse glow of light, in the form of background lighting

Finding the best lighting solution requires planning and skill;  consider natural and artificial sources for a well-balanced space and a pleasant environment.

The use of natural colors in these areas not only is aimed at creating visual accessibility and acuity, but, also, it brings out the benefits of an innate human connection to the natural world. Likewise, organic materials, makes us reflect on a flow of nature;  sustainability has been a topic of consideration for interior designers in the age of post-industrial revolution. Today, as users of spaces, we are all involved in a conversation about energy savings and a socially responsible investment towards our community.


Creating visual interest with accent lighting

Ambient lighting plays a very important role in an overall lighting design for residential just as it does for commercial lighting schemes. It is the soft fill of non-directional light provided by chandeliers and pendants, that helps humanize the space.

Accent lighting, however, will provide a focus of light on furniture, works of art, plants, etc., effectively drawing an area together. It is the layering of various light sources that creates a comfortable and flexible lighting design, and there is no single luminaire that can perform all the required functions of lighting for a space.


Since track lighting casts shadows onto work surfaces, it is not the best choice to be the source of task light. Some interesting effects that can be created with accent light fixtures:

  • adding focus
  • highlighting architectural details
  • backlighting sculptural shapes
  • shining narrow beam uplights against a wall

Track lighting is best used as a source of accent lighting for a number of reasons. It is portable, readily available, and will work in temporary, low-budget, spaces. Even though these light sources aren´t as low-profile as recessed spots, they add a wonderful texture to a space. Like in artists´ studios, where lighting must be highly flexible, thanks to its directional quality, track lighting is more than appropriate when objects and displays need to be moved around.

It is a great solution in situations where there is not enough ceiling depth for recessed units and, in rental spaces, when portability and flexibility are required by changing exhibitors.
