As LED technology continues to evolve, so too grows the efficiency and lifespans of LED lamps. Because LEDs have such long lives (estimated at 35,000 to 100,000 hours), it’s rather challenging to measure precisely how long they really do last — few groups have the patience or resources to measure an LED in various environments for 5 or more years. However, the National Institute of Standards and Technology (NIST) is currently working on such a project.
Without a predictable failure point, manufacturers decided to define LED life as the amount of time it takes for the light to fade to a certain percentage of its original strength. “Lumen depreciation is widely understood in the lighting community and is not unique to LEDs. But it doesn’t come into play when you have a light source that only lasts hundreds or thousands of hours, as with incandescents. On average, incandescents fail before the eye notices a difference in their output,” says Philips Marketing Communications Director Steve Landau.
People in an average office setting can’t tell there is a change in illumination until a lamp has dropped 30% in output. So it is not objectionable to wait until the LED is at 70% of its original spec before you replace the lamp.
This designation is represented by the letter ‘L’ followed by a set of numbers such as:
L70 = time to 70% of original light output. There are other ratings, but this is the most common rating and is universally accepted as the standard to measuring LED life.
For colored accent and exterior lighting, the lumen acceptable lumen drop-off threshold is often considered to be 50%.
Still, even these numbers are highly variable depending on how and where the LED was operated. Things that may influence the LED’s life are line current, ambient temperature, the type of luminaire and the quality of the material used. These differences make defining a LED’s service life even more challenging, since the lamp’s environment can drastically influence its lifespan.
Simply, we can’t determine the service life of an LED without considering its housing and application. This is the major reason why the NIST is conducting their LED study. They are monitoring LEDs in various scenarios with the goal of uncovering a reliable method of projecting how long LEDs will last.
HOW LONG is 100,000 HOURS?
Hours of Operation: 100,000 hours is:
24 hours a day 11.4 years
18 hours per day 14.8 years
12 hours per day 22.8 years
8 hours per day 34.2 years
Although the lighting industry is still learning about the efficiency of LEDs, what we currently know holds real promise for major energy savings in the future. And while the LED bulb you pick off the store shelf may not entirely live up to its 100,000 hour rating, it will certainly outperform most traditional bulbs.
Here’s a fabulous traditional kitchen with a modern feel that successfully mixes different materials from full slab stone backsplash and dual tone tile walls to pro-style range and rustic farm sink.
I think the styling went a little overboard and I’m not a huge fan of the knob placement. But, overall, I think this is a gorgeous kitchen. What do you think?
Spring is starting to creep into everyone’s minds and with that the thought of fresh herbs and vegetables. While it is possible to sow your seeds with snow on the ground, many areas of the country are still too frozen with the harsh arctic blast and ten named winter storms.
Some gardeners use a cold frame, which is a box-like structure with a clear glass or plastic top, to get their seedlings started. However, if you don’t have the space or find it a little too dirty, there is another option – the Urban Cultivator.
The Urban Cultivator Residential is a dishwasher-sized appliance with interior grow lights. Inside are racks that hold flats designed to contain one of three growing mediums — a Sure to Grow mat (suretogrow.com), sterilized soil or landscape fabric. In these, users can grow 50-some greens — including beet-tops, baby broccoli, wheat grass, pea sprouts, radishes, mustard greens, lentils, nasturtiums — as well as any number of herbs.
The unit is not difficult to install and requires a water connection similar to a dishwasher. You can choose between different door screen options (clear, frost, half-tone and dark) and even add a custom panel to match your cabinetry.
The Urban Cultivator will allow you to grow fresh herbs 365 days a year and know that they are pesticide free and healthy for your family. The cost savings for growing your own micro-greens can be as high as 90% according to research.
Your Urban Cultivator can be operated between 55 and 90 degrees with a relative humidity between 30% to 60%. The automated system does all the work and provides measured water to and from each grow tray. If your unit is set up as a stand-alone unit, you will need to empty and refill the water reservoir once a week when the indicator light is on. Four humidity domes are also included with the unit to aid in starting seeds.
A larger commercial unit is also available for restaurants and cooking schools where larger supplies are demanded. Besides herbs, small vegetables such as cherry tomatoes can also be grown. Pricing starts at $2,200.
LED integration into surfaces is growing by leaps and bounds and stands to add an exciting dimension to interior design. Let’s look at what is making news.
The Cell+LED Carpet from Lama Concept
It’s hard to believe it’s been 7 years since this carpet made it’s debut at the Paris Airshow fitted into the isles of the Airbus A350. Since then it’s been used in various commercial applications and even in the Land Rover LRX Concept.
The carpets and rugs are made from 100% wool felt strips that are formed around eye-like forms – like knots in wood. Some of these knots are replaced with LED lights and oriented with the direction of the strips. The carpets can be created to form a directional path with the LEDs, or the lights can just be placed randomly for a glittering array.
Although this carpet might not work with every decor, it’s an innovate approach to flooring that opens the door to endless design possibilities.
Phillips and Desso
Two Dutch-based companies, Phillips Lighting and carpet maker Desso, recently announced a partnership to create light-transmitting carpet–smart flooring capable of displaying all kinds of information.
Desso envisions the new light emitting LED carpet as serving several purposes. One would be to quickly and intuitively guide people through buildings including to designated safety routes and exits. Another would be to add to the ambiance and atmosphere of public spaces. The carpet would add “lighting, design and color” as the joint statement from both companies explains.
For now, the partnership is limited to the EMEA (Europe, Middle East, and Africa) and the official product is slated for sometime in 2014. Who knows, one day we may be able to turn an average living room into a disco lounge with the touch of our phones or tablets and use the same system with our fire alarms enabling it to send a signal to specifically light the best way out of our homes.
Premier Copper Products has introduced a new line of vanities made from recycled solid oak wine barrels and featuring recycled copper sinks.
The new vanities are repurposed from Napa Valley barrels and air-dried in the Arizona climate for two and a half years before being dismantled and rebuilt into furniture by Arizona designer and craftsman John Koering.
The barrels measure 28 ins. wide, 34.5 ins. tall and feature an 18-in.-by-13-in. door (the original bung hole is repurposed for a door opening). Each unit also comes with a pre-installed 17-in. oval hand-hammered copper sink and drain.
The vanities are available in three non-VOC finishes and are priced at $2,398 (for vanity and sink only) and $2,726 (for vanity, sink and faucet package).
I love this image I stumbled across on the internet. The stone ledge is a great way to add more surface area for items like soap and finger towels. This is the perfect vessel for letting your imagination run wild.
Premier Copper Products is a Phoenix, Arizona-based importer and designer of handmade copper products from a plant they control in Mexico.
TOTO’s new Traditional design Connelly Suite is inspired by the “timeless sophistication of classic Hollywood imbued with the curvilinear aesthetic of the Arte Deco period.”
When looking for a clean lines and bold geometric shapes with sophistication for a fresh and uncluttered look, the TOTO Connelly Suite is an ideal choice.
The Connelly Undermount Lavatory measures 15″ by 15″ leaving plenty of space on the countertop. The deep basin reduces waters splashing, and its SanaGloss glaze saves homeowners time cleaning as the super-slippery surface repels bacteria and soap scum. It is available in Cotton, Colonial White, Sedona Beige, Bone, and Ebony.
An example of TOTO’s inclusive design philosophy – providing ease of use for all ages – the sophisticated faucet’s lever handles serve as a graceful counterpoint to the vertically detailed, gently flared bases, which lends a tactile element to the fixture’s design.
The spout has an organic curve that adds an elegant and soft design element to the sleek lever and base. The faucet has WaterSense technology and only uses 1.5 gallons per minute without a decrease in pressure. The faucet is available in an array of finishes including Brushed Nickel, Polished Nickel and Polished Chrome.
The Connelly Dual Flush High-Efficiency toilet is an elegant design with a strong geometric tank supporting a sizeable lid. The inclusive-design Connelly toilet is 17” from base to seat top, making it ergonomically correct height for a person to comfortably sit down and rise from it with ease. It is available in Cotton, Colonial White, Sedona Beige, Bone, and Ebony, with trip lever finishes available in Polished Chrome, Brushed Nickel, Polished Nickel, among others.
The design specializes in its Dual-Max Cyclone Flushing system uses bio-mimicry to eliminate the need to scrub due to streaking after flushing.
Inspired by cyclones in nature, TOTO engineers harnessed the power of gravity and water to spin away waste. To achieve their vision, they designed a seamless bowl interior with a concave rim to channel high-speed water jets for superior bowl and rim cleansing action. Each flush spins away debris, matter, and bacteria, which reduces the time needed to clean the unit.
The heat is on with the Flir One Thermal Image Device
The Flir One released the very first personal thermal image device designed specifically for your iPhone 5 & 5s at CES 2014.
As the first and only personal thermal imager for the consumer market under $350, Flir One is compact, easy-to-use, compatible with the iPhone5 and 5s and fits on the phone like a protective case.
Once mounted, the device displays a live thermal image on the phone’s screen, giving users unprecedented ability to “see” in an array of conditions, including complete darkness.
The device combines an infrared thermal camera that converts energy (heat) into an electronic signal which is then translated into an image on to your phone’s screen. With the ability to see heat, it allows you to identify those pesky things like moisture detection, energy loss, and many more creative possibilities.
•The onboard battery source powers the device for more than two hours of continuous use; can also be configured to boost the iPhone5 and 5s* battery life by 50 percent.
•It can see in the dark, observe invisible heat sources, see through smoke, and even see through some materials. Scene range temperature: 32 °F to 212 °F (O °C to 100 °C)
•MSX Blending (Adds visible spectrum detail to thermal images and enhances resolution)
•Video capture (.mov format), Still image capture, Choice of color palettes (B/W, W/B, Rainbow, Contrast, Arctic, Hot/Cold, Iron)
While the case adds a bit of chunkiness to your svelte handset, it’s a minor trade-off for awesome Predator-like heat vision. And while the iPhone 5 version of the Flir case will be available this summer, the company is working on an Android version as well.
Whether you want this device to detect a leak, look at deer in the middle of the night, or help you navigate through smoke you have to admit it’s pretty cool.
I can’t tell you how many times I’ve had a contractor scratch his head and look at me with glazed eyes as I try to describe what I need from his electrician to provide a drawer for my clients to charge their devices out of sight.
The Docking Drawer™ from JTech Solutions removes the hassle with a convenient and safe way to integrate a grounded outlet into a cabinet drawer.
The outlet comes with two grounded 3-pronged outlets and two USB outlets with integrated on/off safety switch. The Docking Drawer™ is UL 962 approval pending and max rated for 3A/375w. The circuit is protected by 5A pop out breaker accessible from inside the cabinet.
The Docking drawer is best installed during new construction but can be retrofitted if you can run an electrical line to the rear of the cabinet. The drawer may need to be modified since the device has a limited reach. The device alone costs $139.00.
I think I might need to test one and see how it works with my standard cabinet specs.
Inalco Slimmker Click takes the high-performance characteristics of the Slimmker Floor product and marries it with traditional tongue-and-groove laminate flooring plywood backing.
This creates an easy-to-install flooring option. The semi-translucent white porcelain collection can be made in many lighter porcelain designs which allow for backlighting much like an onyx or alabaster slab.
Inalco’s Slimmker Click Collection is lightweight, versatile and ideal for places where surface coverings are regularly changed.
The Vinotemp Cava credenza is the perfect solution for serving and storing your wine collection when you don’t like the look of a stainless steel and glass box.
The Cava Credenza has the ability to hold up to 36 bottles in two independently controlled refrigerated units, up to 18 wine glasses in the central hanging stemware racks, and all of your favorite wine accessories in its 3 storage drawers.
The Cava Credenza has dual thermoelectric cooling systems with 53° to 64°F temperature range and soft interior lighting to beautifully display your favorite wines without adding heat. It is available in two finishes: Espresso and Rich Maple.
The Credenza is 54″ wide, 22″ deep, 40″ high and weighs close to 250 pounds. Pricing is set at $1,780 plus $415 freight. It does not meet CA prop. 65 regulations.
While this credenza does not hold a lot of bottles, I think the use of furniture feet give it a lighter appearance than other models on the market. I’d prefer if one cooler could handle large or oddly shaped bottles. If you place a champagne bottle in this credenza you will most likely reduce the overall bottle capacity that can be stored.
