Lutron Electronics, the leader in wireless lighting and shade control, today announced several expansions to its signature lighting control systems, bringing fashion and functionality to the forefront of lighting control.
Lighting designers are often challenged with finding coordinated architectural finishes that boast a clean look while maintaining the ability to control all load types. HomeWorks QS and RadioRA 2 systems, known for their unparalleled total home lighting control, will now have greater options of architectural accessories, allowing users to have a coordinated, high-end look throughout their home.
Palladiom keypad The sleek and intuitive design of the Palladiom keypad ties into the HomeWorks QS system, bringing a subtle elegance to any home that is already benefitting from the total lighting control of the HomeWorks QS system. The Palladiom keypad is simple to operate and provides a beautiful architectural aesthetic with a sleek, minimalist design that complements any décor. It is the first of its kind to feature buttons and faceplates made of the same material – plastic, glass or metal – for a coordinated aesthetic. Its customizable button layout and programming accommodates virtually any function. Additionally, it has large, tactile buttons with backlit, engraved text that are simple to operate and easy to find in a darkened room. Its variable backlight intensity controlled through Lutron’s Dynamic Backlight Management provides the right brightness for any ambient lighting conditions.
GRAFIK T An instant modern design classic, GRAFIK T marries advanced Lutron touch dimming technology with intuitive, minimalist design. Its aesthetic is elegant and timeless, with a faceplate that appears to float off the wall. It has the quiet and modern elegance of Lutron touch technology, no knobs, buttons, or sliders—just touch anywhere along the LED light bar to set lights to the right level. Lutron’s HomeWorks QS and RadioRA 2 systems will feature a new GRAFIK T phase selectable dimmer that not only works with incandescent halogen lights like the previous version, but also practically any load type, including LEDs. The dimmer continues to add the unique, distinct style of this architectural control family to any space.
Up until now, only the GRAFIK T dimmer and switch were available for the HomeWorks QS and RadioRA 2 systems. This keypad replaces a light switch and offers system dimming control of the attached load while also functioning as a keypad. It will boost performance while keeping a consistent, high-end look throughout the home.
“Lutron is a leader in providing sleek designs and aesthetic enhancements to every one of its product lines,” said Rich Black, Director of Residential Business Development at Lutron Electronics. “A focus on fashion is the future of lighting control, and the HomeWorks QS and RadioRA 2 systems just got styled.”
Often times, to have unique aesthetics, users lose the ability to couple devices together. Lutron is now offering new accessory devices, including 15 amp and 20 amp duplex receptacles, USB and GFCI receptacles that allow Palladiom and GRAFIK T to be ganged. The result is a coordinated look throughout the home.
seeTouch C.L. Hybrid Keypad The seeTouch C.L. Hybrid Keypad, known for its easy retrofitting and high-end architectural look, will now have the ability to control LED loads while maintaining its high performance dimming, flexible button configurations and custom engraved buttons with backlighting.
These new products will be available in early 2016 with the following suggested list prices:
- the Palladiom keypad: from $300, depending on finish
- the GRAFIK T phase-selectable dimmer: $299
- the GRAFIK T hybrid keypad: $549
- the seeTouch C.L. hybrid keypad: $399 for RadioRA 2 and $499 for HomeWorks QS
Going wireless is the way to go, right? After all, you probably already have a wireless computer network in your home. Maybe wireless printing. You may have cut the cord on phone service—perhaps even cable TV. So why not go wireless with electronic lighting control as well?
With so much working wirelessly in your home already, why not go with a wireless lighting control system that lets you shut off all your home’s lights from one location, dim lights and set cool scenes. It will save you the hassle of having to run wires from the keypads to a central processor, which is how most wired lighting control systems work.
“You should never have a home without wireless in the future,” says Roger Stamm, international sales director at Lutron Electronics, manufacturer of both wired and wireless lighting control systems.
So that’s it. Wireless wins, right?
Not so fast. There are advantages and disadvantages of using both technologies. And what you ultimately choose could depend on several factors:
- Is your home already built or is it in the process of being built?
- What’s your budget and what can you pay up front?
- The reliability of the system.
- The features and size of the system.
- And future add-ons and technologies.
Especially note what Stamm said last: “in the future.” Wireless lighting control is certainly in the here and now. And we’re seeing more and more of it—with good reasons. But it’s not the winner of the lighting world by default—and least not yet.
It looks like we’re going to need a lighting technology smackdown between the wired and wireless lighting. Let’s go a few rounds and rate them in various categories—and you can judge which one best fits your needs.
Round 1: New Construction vs. Retrofit
A few years ago, the answer was easy: If you’re building a new home or an addition and the walls aren’t closed, you wire, wire, wire.
“If you can wire, your first choice should be a wired network,” says Hector Morazan, international sales manager for high-end lighting system maker LiteTouch.
So why are we seeing more and more wireless systems in new homes? It could be that the walls were closed by the time a lighting system was specified. And let’s face it: wireless systems free you from the hassle of running wires.
“When the walls are up and everything’s done, wireless offers another option,” says Ian Hendler, director of business development for Leviton Manufacturing, a mid-market lighting systems maker.
“Wireless is for when all existing house wiring is done, and you don’t want the disruption of pulling new wires,” agrees Lutron’s Stamm.
That’s easy enough: Wire for a system if you can. If you can’t wire, go wireless.
But wait: There may be another consideration: “Wired is probably best for larger homes in new construction,” says Hendler.
So smaller homes, say under 3,000 square feet, should opt for wireless, even if the walls are open and wires can be run? That’s a personal choice, and may be tied to budget considerations.
Winner: It’s a draw. Wire in new construction, go wireless in retrofit.
Wireless lighting systems are going beyond just operating lighting.
Round 2: Cost Benefits
In total cost, it is generally perceived that wired lighting systems, by the nature of their typically larger sizes, are more expensive than smaller, wireless systems. For example, a typical wired Lutron HomeWorks system will cost $15,000 to $25,000 and up, while a wireless Lutron RadioRA starter package begins at about $1,300 and can cost $3,000 to $4,000 to cover a couple of rooms.
But guess what? In terms of the per-product pricing, wireless is still a bit more expensive. Lutron, for example, sells a wireless HomeWorks system, and its dimmers go for about $200, while the wired dimmers run between about $150 and $160. Wireless is more expensive per component because the RF (radio frequency) communications and sometimes the processing are built right into a dimmer, light switch or keypad.
Though, says Lutron’s Stamm, “The cost of wireless has come down closer to the cost of the wired lighting control system.”
The cumulative cost of a wired system typically reaches into the five figures because a home with a wired system tends to be larger houses—and with a wired system, you have to spend much more up front. You have to get all those wires into the walls before they close; therefore, the entire system is often bought and installed at one time.
With a wireless system, you can start smaller to save money, and add on as you can afford it. “It gives you the opportunity the scale back to do some things, and it is possible to add on in the future,” says Stamm. But go from a couple of rooms to most of the house with wireless, and you, too, could enter five-figure territory—while paying more per dimmers and keypads.
“If you can do a wired system, you can get a cost benefit,” says Leviton’s Hendler.
So wired strikes back. But wait … You also have to figure the cost of the labor of putting wires into the walls—especially if it’s a retrofit—and that can make any savings realized with a wired system a wash.
Then again, there’s set-up time to consider for a wireless system. The punches are flying fast and furious.
Winner: Advantage to wireless, because you can start with a much lower budget.
Round 3: Reliability
This is where you can run into problems with a wireless lighting system, though wireless lighting technologies and their reliability have improved steadily in recent years.
“Reliability with wired is rock solid,” says Leviton’s Handler.
“People still run wires for the feeling of reliability,” echoes Lutron’s Stamm. “And in some cases, wireless is not suitable.”
For example, concrete walls or metal mesh in the walls for plastering can significantly affect the range and reliability of wireless communications in a home—as well as the ability simply to switch on and off lights via a wireless control system.
“Even with WiFi coverage of about 200 feet, you could have problems with concrete,” says LiteTouch’s Morazan, who sees this problem frequently in southern climes.
“There are lots of ‘moving parts’ with wireless,” says Vantage Controls‘ Andrew Wale. “And you have to pay attention to the integrity of the network.”
The good news is that wireless lighting control technologies have improved significantly in recent years. Lutron’s RadioRA 2, for example, communicates over multiple channels to avoid interference with the transmission of an RF signal. “Adding occupancy sensors and other devices for an RF network means more traffic,” says Stamm, “so we had to improve the technology and protocol in the network to handle that traffic.”
“Mesh” networks like ZigBee and Z-Wave, in which each enabled device like a ZigBee or Z-Wave dimmer can become a redundant communicating network node like a repeater, have improved in their reliability as well—so much so that LiteTouch uses a Hybrid wired and wireless lighting system with its modular FiveK processor, in which the wireless components are ZigBee-enabled, but only communicate point-to-point with the processor. Lutron’s RadioRA, by contrast, does not require a central processor.
“What has increased the reliability in wireless lighting is the increased processing power and open standards,” says Leviton’s Hendler, whose ViziaRF wireless lighting products use the Z-Wave protocol.
Nevertheless, “Hardwired solutions are more robust,” concludes Vantage’s Wale. Few would disagree.
Winner: Advantage to wired systems, but wireless is catching up.
LiteTouch offers a hybrid wired and wireless system that utilizes the company’s modular FiveK processor and uses a point-to-point ZigBee wireless technology.
Round 4: Features
Will you generally get more features with a hardwired lighting system? Yes. Is this due to the technical limitations of a wireless system? Not really, says Lutron’s Stamm.
The company’s wireless RadioRA system was first introduced for lower-cost and retrofit solutions, “so we limited the feature set a little bit. Now the cost of the technology has gotten better, so we can add those features back,” Stamm says.
The newer RadioRA 2, for example, can interface easily with motorized shading systems and works with all sorts of new devices and features like smart thermostats and plug-in appliance modules for energy management. It has also grown from being limited to 32 dimmers to being able to handle 200 devices. If your home needs more, you can upgrade to the wireless HomeWorks version that supports 1,500 devices.
So the feature limitations with wireless are largely the result of economics.
“With Vizia, the biggest thing we’re seeing is security guys pushing it real hard and bundling it with energy management,” says Leviton’s Hendler.
ViziaRF products can work with other Z-Wave devices like Mi Casa Verde’s Vera system, which has become a popular mid-market controller for Z-Wave audio/video, lighting, and more. One can set up a Leviton system, transfer control to Vera, and it can calculate all the energy being used at the switch level. It can even be controlled via an iPhone app, and work with Z-Wave compatible door locks. Very cool and affordable.
Sure, you can still get more features and more robustness from a wired system, but know what you want to do and research what each type of system can do for you.
Winner: Wired systems, for now.
Round 5: The Future
Hardwired lighting control systems are still the better bet for being reliable and more robust. These advantages are becoming slimmer and slimmer, however, as wireless technologies improve and become more cost-effective. If you have open walls and can afford a wired system, by all means go for it.
Budget, however, may be the knockout punch for wireless over wired for most: You can start with a wireless lighting system at a much lower cost, and build on it from there. Just check for potential interference and range issues—and you should be golden. The reliability and robustness of wireless systems have improved greatly.
We’re also seeing some really cool technological applications, such as energy-saving kinetic energy, in which keypads can be powered on their own, using the energy resulting from key presses. PCS’ (Powerline Control Systems) PulseWorx RF system and Leviton’s commercial-grade LevNet wireless system use technology from EnOcean to do this, and our bet is that we’ll be seeing a whole lot more of it in the future. Though it shouldn’t be limited to wireless lighting control systems.
As Lutron’s Stamm says. “You should never have a home without wireless in its future.” And with many more retrofit home projects taking place today, you can see where this is going. But still, wire if you can.
Leviton’s Vizia RF+ wireless control line features switchable outlets, and plug-in remotes.
