LED Lighting

1. You may never change another light bulb.
The LR6 lasts more than 20 years (50,000 hours) under normal use. That makes life simpler, especially in hard-to-reach installations.

2. Look at a home in a different light.
The quality of light from the LR6 is unmatched.
There’s no harsh glare, just warm, beautiful light.

3. The heat is off.
Unlike incandescent fixtures, the LR6 is comfortable to the touch, and it reduces the burden and cost of the air conditioning system.

4. Great light has never been so green.
The new LR6 uses 85% less energy than a conventional incandescent and less than half that of a comparable fluorescent. And unlike any fluorescent, the LR6 contains no harmful mercury.

5. Shedding light on lower costs.
Savings like these mean the LR6, in typical use,
more than pays for itself in
electricity savings.



 Fiber Optic Advantages

  • No electricity at the point of illumination– fiber optic cables carry only light to the point of illumination. The illuminator and the electricity that powers it can be many yards away from the objects or areas being lit. For fountains, pools, spas, steam showers or saunas – fiber optic systems are the safest way to provide illumination.
  • No heat at the point of illumination – fiber optic cables carry no heat to the point of illumination. No more hot display cases and no more burns from overheated lamps and fixture, and if you’re lighting heat-sensitive materials like food, flowers, cosmetics or fine art, you can have bright, focused light without heat or heat damage.
  • No UV rays at the point of illumination – fiber optic cables carry no destructive UV rays to the point of illumination, which is why the world’s great museums often use fiber optic lighting to protect their ancient treasures. For preserving fragile and precious items, fiber optic systems provide bright but gentle light.
  • Easy and/or remote maintenance – whether the issue is access or convenience, fiber optic systems can make re-lamping a breeze. For fixtures that are difficult to access, the illuminator can be located in a place that’s easier to reach, and for multiple small lights (stair lights, paver lights or chandeliers) changing a single illuminator lamp re-lamps every light at once.


The HSL 3000, a hybrid lighting system developed by Sunlight Direct, carries the actual light of the sun indoors. The system’s 48-inch primary mirror concentrates light into a secondary mirror, which strips away the infrared and ultraviolet components, and directs the visible light into the receiver. A tracking system has two motors governed by a GPS microprocessor, which can calculate the position of the sun within half a degree. This enables the mirror to follow the sun across the sky like a sunflower, gathering in maximum light intensity throughout the day. The tracking system itself requires very little power to operate. It could be supported by a small solar cell – equivalent to a 9-volt battery (which would last about a week).

“When come in, in the morning and you’re tired, and you’ve got your coffee in your hand and you’re not quite awake, you like seeing the reddish glow… the same type of light as outside.” Dr. Duncan Earl, CEO of Sunlight Direct, explained the psychological appeal of his company’s hybrid lighting system to the Canadian Discovery-Channel’s host Jay Ingram.

People are more comfortable “waking up with the sun” and as the light becomes white they work through the day. “And at the end of the day when there’s a reddish glow, you know it’s time to go home.” Dr. Earl’s eyes twinkled and his face lighted up with a satisfied smile as the camera caught the interior light brightening to noon and fading toward evening russet in the brief time he took to describe this very effect.
It’s a nifty demonstration of his company’s finesse in controlling the intensity and visual temperature of light.

Hybrid Lighting Blends Solar with Conventional

The company may offer several versions.  Some will provide a hybrid with fluorescent bulbs, adjusting the fluorescent depending on the amount of sunlight available. Others may be a stripped-down sunlight-only model.


In the automatic hybrid system, a Daylight Harvesting Sensor detects the continuing increase of sunlight strength in the morning, and accordingly reduces the percentage of fluorescent light. Late in the day, the process is reversed. The computerized controller thereby maintains an ideal level of illumination for office work without anyone having to adjust the settings.

Pure visible light – without the uncomfortable infrared or the damaging ultraviolet – is conducted through the optical fibers into the building. The fibers feed light into an acrylic rod, the non-electrical equivalent of the fluorescent tubes between which it is sandwiched in the commercial hybrid lighting fixture. The sunlight, which would otherwise continue in a straight line, is diffused outward into the room by means of hundreds of tiny scratches on the surface of the rod. One HSL 3000 is capable of lighting approximately 1000 square feet.
