Ketra Lighting Explained

Ketra specializes in bringing natural light to indoor spaces. With the ability to generate a wider gamut of color via precision optics, Ketra’s technology allows light to be tailored to every room and its purpose. The result is a more comfortable atmosphere, and improved overall wellness.

The Problem with Poor Lighting

We’ve all strained our eyes through inadequate lighting, or squinted through lighting overkill. Less often discussed is the huge impact color temperature can have. Indoor light feels “right” when it matches natural light as closely as possible. The blue hue of a rising sun, a warm sunset, the low flicker of a candle flame… These natural sources trigger emotional and biological reactions from us all. A contrast between our indoor lighting and the natural light around us can cause measurable discomfort.

Ketra’s Solution

Most lights offer a single color. Others mix red, green and blue sources to offer a wide range of color estimations. Ketra, however, has designed custom chip drivers in their lamps to provide the highest quality, most accurate light source across a full range of colors. Each Ketra fixture can then be individually tuned to the area around it, for a more precise lighting design throughout the space. Each fixture can then be programmed to adjust through the day automatically, matching the sun’s temperature as it rises and falls.

Ketra’s various luminaires and lamps use custom silicon domes made to utilize precision optics. Precision optics help highlight a space’s architecture and furnishings with uniformity of color and intensity – free from distortion and unwanted reflections. While traditional optics have proved sufficient for single color points, Ketra’s full spectrum requires a more advanced approach. They start by packing their LEDs as closely as possible under a silicone dome, then align the light via a reflector optic. Finally, a secondary pillow lens smooths out the beam before it spreads into the room.

The Impact

At Cloud9, we believe that natural lighting will improve the space, but more importantly your overall wellness. Harsh lighting can impair focus. Cooler lighting can keep your body alert when you should be relaxing, while warmer light can do the opposite. It’s important to let ourselves thrive through the day and rest in the evening. Ketra’s technology produces dynamic, high-quality light that helps you feel more connected to nature. A well-lit space can mean a more comfortable work, living and headspace.

The Demo

Of all the lifestyle technology we install in the homes of our clients, the most dramatic impact on lifestyle (and the most dramatic reaction when demoed) is probably from Ketra. The flaws we’ve come to normalize in indoor lighting suddenly become glaringly obvious when seeing Ketra’s full spectrum lighting experience against normal LED or halogen lighting.

If you are in the New York City area and would like to experience Ketra, set up an appointment and we’ll schedule a demo for you at our showroom in Union Square.

Lutron Motorized Shades – Considerations

In 2019, Lutron offers two styles of smart roller shades that our clients keep asking for. The key difference is how they are mounted.

  • Standard Roller Shade (Sivoia QS) – Usually mounted out of sight.
  • Palladiom – Mounted proud.

The Trouble with Motorized Shades

It is an unfortunate reality of the motorized shade world that brackets are hideous. Lutron has historically solved this by tucking the roller and motor up into a pocket or cavity. This way the shade is only seen once it drops. 

This is a tricky endeavour anyway, but especially where space is tight (such as in New York City, where most of our jobs take place.) It becomes exponentially challenging when trying to hide rollers for both blackout and privacy in the same cavity. The rollers need to sit as close to each other as possible without any movement being obstructed (often by stacking one on top of the other and having them descend on opposite sides of the roller.)

The Solution

By designing a beautiful bracket system that doesn’t need to be hidden, Lutron has created a new opportunity to mount smart shades proud. This is Palladiom. The brackets come in all sorts of finishes, letting you match your door handle finish, for example. You can also match the hem bar on the bottom of the shade.

Palladiom also makes keypads with gorgeous finishes in metal, glass and plastic. Each button is backlit and engravable. They match the same high quality and minimal aesthetic as the shades themselves, and give a satisfying tactile response when pressed.

While easier to install in many ways, wiring for Palladiom shades is actually more of an exercise in precision. While wire slack for traditional roller shades can get buried in the same pocket, Palladiom brackets are so small that the wire needs to be in the exact perfect location, or else it will be visible after installation and tarnish the aesthetic.

Options and Impact

Because it’s Lutron, options within each approach are practically limitless. Fabrics, colors and transparencies all run a wide gamut of choices. What used to be an obstacle designers and architects had to deal with, is now a design element they can fine-tune.

And the impact should not be understated. If shade transparency is set too low, you don’t allow enough light into the room, but you also don’t grant yourself any more privacy than if you were to increase transparency to say three, five or seven per cent. By choosing transparency meticulously you can ensure privacy while still letting natural light through. Of arguably more importance, you can make your space appear bigger by seeing silhouettes of the world around you through the shades, rather than a single plane of material.

Finally, blocking UV sunlight that can bleach furnishings and overheat your home is of great value. Lutron can automatically do this based on an astronomical clock. Beyond time of day, it knows the latitude/longiture position of the building and can automatically adjust based on the position of the sun.

Lutron even lets you select separate colors for the inside and outside of the shade. Many buildings specify a single color for shades in order to maintain unity from street view. This lets you play with color on the inside of your home while remaining compliant from the outside.


An important question to ask when specifying for shades is whether they should fall to the backside of the roller or the front side. If we’re mounting outside of the window frame, falling to the back of the roller probably makes perfect sense, but if you’re inside the window frame you need to ask whether the window will open and shut. If so, you might have window hardware that can get in the way, in which case the shade falling forward makes more sense.

Why is this so important to determine up front? When we wire the shade for power and control, spinning the whole shade around to flip where it falls will be a huge issue.

Performance and Noise

The mark of a really great shade is not only smooth motion, but sound implications. We’ve listened to other shade manufacturers out there, and were surprised at the audible mechanics present when adjusting the shade. Not the case with Lutron, whose Palladiom and traditional motors are as quiet as they come.

The hem bars on Lutron shades actually align with one another digitally. This lets Lutron know where each shade is in position to the rest, and maintain perfect alignment in movement. Without this technology shades can misalign or “sawtooth,” which is to put it lightly an undesired look.

What about Battery Powered?

When given the choice, we will always choose a hard-wired connection for its rock-solid reliability and independence from your wireless network. When wired is not an option however, Lutron does offer a straight-forward option with their Serena line. Nixing the need for hard wiring makes them far easier to retrofit, and the batteries last for around three years.

Savant Systems 2019

Savant is beloved as a smarthome platform for one crucial reason: It is incredibly simple to use.

It takes complex tasks across un-connected devices, and brings them into a simple interface with a barely noticeable learning curve.

That learning curve is around two items: The handheld remote and the App.

Handheld (The Savant Pro Remote)

The handheld remote is an example of refined design. It has the dedicated buttons of a classic remote, a touch screen for more advanced features, and voice control built in. Yet, it doesn’t overwhelm. There are fewer than 20 buttons on it. Hold it in your hand and you’ll immediately notice the weight, button placement and tactile experience just feel right.

Meanwhile, the touch screen on top (also ergonomically where you would expect it to be) floats your most commonly-viewed channels to the top for easy access. With one swipe you can adjust your other available features (music, lighting, shading, thermostat, etc.)

A central voice control button offers yet another way to order up channels, turn on lights, and activate scenes.

The Savant Pro is, without exaggeration, the cleanest and simplest way to wrangle all of your devices (Apple TV, Roku, etc.) into the same interface.

The App (The Savant Pro App)

Beyond TV, most Savant users will reach for the Savant Pro App on their phone or iPad to control the rest of their home. The quality and layout of the interface is drop dead gorgeous. It’s also the same no matter which integrator you hire (this is important for users with multiple homes.)

Savant’s App accomplishes personalization by using photos of each room to identify them. This lets you scroll through and select rooms without thinking, but more importantly lets you adjust the room by tapping elements in the photograph. For example, tapping a lamp in a rooms photo will turn it on right in front of you.

Smarthome platforms used to require a professional to physically come to your house whenever you wanted to change your favorites, or “scenes.” Savant changed this by letting users easily adjust a room’s settings, name it as a scene, and call it up later. You can even schedule its occurrence based on a wide array of circumstances.


Of course, a lot of Savant’s power comes from the programming behind the scenes. Their constant and painstaking generation of drivers to make 3rd party devices compatible is impressive. Their deeper integration with leading brands like Sonos, Lutron and Nest make controlling them through Savant feel as powerful as if you were using the brand’s native controller.

They’ve also integrated with Amazon Alexa, letting you control your home with any Alexa enabled device.


Nest is great for simple homes, but falls short when trying to control multiple styles of heating and cooling systems (i.e. radiant floors with a mini split system.) This requires separate thermostats and more wall acne… Savant is different. They make it simple to bring many zones across multiple systems into one clean system.


Video matrixing (or sending one video source to any number of TVs) used to require big expensive switchers, which were typically limited to 16 inputs and 16 outputs. Savant, along with Video-over-IP technology, now allows as many inputs and outputs as you need, scaling infinitely over your network. (The same for audio.)

For most of our clients, this means that instead of having one cable box and one Apple TV for each room, they can have one for the parents and another for the kids. Anyone can then pull up any device onto any screen in the house.

Oh, and Savant absolutely slays it with video tiling. Their ability to turn one screen into a quad screen or picture-in-picture is as simple as dragging and dropping in the Savant App. They do this very, very well.

Camera Integration

Security cameras integrate smoothly into the Savant App via IP. The end user sees a little camera icon, bringing them into a live feed of all of their cameras in one clean space.

But how do you limit access to camera feeds so that not every guest will find them?…


Savant makes it easy to assign different profiles for different users. You wouldn’t want your kids to be able to randomly turn on music in the master suite. You may not want a guest of housekeeper to have access to every camera. Savant makes it easy to assign different levels of access to different profiles, then sign into different profiles on different iPads, and distribute accordingly.

The Savant Approach

Savant does most thing exceptionally well. They look at user experience with the understanding that 99% of the time people are likely to control their home in a similar way. Rather than labor over the 1% that requires deep custom programming, they’ve decided to perfect the 99% and say “no” to the 1%.

It’s a similar approach to Apple, who limits both their product line, and the menu options within their software, down to a “don’t make me think” experience. Clearly Savant admires the Apple approach, seeing how they use the Apple ecosystem. The actual brain for a Savant system is a Mac Mini, and Savant programming can’t even take place on a PC. Every Savant programmer uses a Mac.


Savant requires network communication for all of its devices. Consequently, a weak network equals a weak experience. Two important elements a Savant-ready network must have are:

  1. Wireless access points strategically placed across the home to blanket coverage.
  2. The ability to prioritize traffic so that more important tasks don’t get interrupted by less important tasks (i.e. YouTube streaming.) 

We like Packedge BakPak for homes and Cisco Meraki but businesses. The key takeaway, however, is that the typical router provided by your ISP won’t suffice for this demanding a system. Ensure you have a strong network, as your network is the backbone for your smarthome.
