CES 2019: Kohler’s $8,000 intelligent toilet is as ridiculous as it sounds | Led Ceiling Light Fixtures

If they just quit, it’s not LED wearout; the driver has fried. Either bad soldering, heat, or line spikes.

The other configurations include two 4×7-inch rectangular units that consume 9W and 20W while producing 1400 lm and 2820 lm respectively. These Vizion DC Retrofit Engines are useful for retrofitting wall and ceiling mounted luminaires with or without plastic or glass lenses. In fact, Fulham says that they can be used for most lighting installations that need a dimmable, preassembled driver and module in a compact form factor.

7. The other side of the power-supply PCB has the switching inductor. The supply seems to operate at 500 kHz. The base is plastic, so electromagnetic interference (EMI) must not have been a problem for the Cree engineers.

The new-generation Sonata is the first sedan designed with Hyundai’s Sensuous Sportiness design language. It is a fully transformed vehicle showcasing a sporty four-door-coupe look. The 2020 Sonata represents Hyundai’s new focus on creating emotional value using proportion, styling and technology. From the front, the 2020 Sonata is unlike any other Hyundai. The design is all-new, with cues that don’t immediately appear Hyundai-like and thus encourage customers to take a second look. The 2020 Sonata embodies the evolution of a new Hyundai design theme—a portfolio of vehicles that, like chess pieces on a board, look and behave differently, each with a clear role and function, but together exemplify a cohesive team.

They have inspection on a Chinese assembly line? I think they just put 120 volts on it, and if it lights it ships.

Tucked into a lower shelf in the lighting isle at the hardware store, a few lonely incandescent bulbs waited for some Luddite consumer. Picking up a box, I read the rated lifetime: 1,000 hours.

Hazardous environments are high-risk places where potentially explosive materials or harmful substances that are susceptible to reaction with external environment, are manufactured or processed. The importance of installing safe and efficient lighting solutions in these environments cannot be ignored, because they are usually located in very remote, inaccessible locations. With 318 deaths in the manufacturing industry and 89 deaths in the mining and quarrying industry in the United States alone in 2016, according to the US Department of Labor, there is a critical need to provide appropriate lighting solutions in these areas. The market for lighting hazardous locations is driven by the emergence of LED lights as a viable alternative to traditional lighting applications, owing to their sturdiness, reliability, and non-toxic nature. LED-based applications offer optimal efficiency, as they do not contain any flammable substances and offer higher cost effectiveness and lighting performance, making them a preferred choice in a wide array of industries, such as mills, pharmaceuticals, fireworks agencies, etc.

Smart switches, on the other hand, are far more complicated to install—to the point where some users might be uncomfortable dealing with exposed wiring and would prefer to hire an electrician. Smart switches, however, provide more flexibility in many installations.

“More and more customers are retrofitting existing luminaires to simplify getting LED lighting into their facilities. Therefore we are seeing a growing demand for LED retrofit kits, with special emphasis on energy efficiency,” said Edwin Reyes, Product Director, LED Light Sources, for Fulham. “These new Vizion DC Retrofit Engines deliver more light with less power, and their versatile design and dimmability gives our distribution and OEM partners new components they can adapt for any type of luminaire or application, including indoor and outdoor applications”

Bluetooth Mesh is rapidly gaining market momentum as a preferred approach to create a wireless lighting ecosystem. Bluetooth has been around for decades and is a mature, open standard for device-to-device communications. Bluetooth Mesh is somewhat newer but is based on the same open standard, so it’s easier for manufacturers to develop products that are assured to be compatible.

The fifth point is that the earlier LEDs were a lot dimmer – the manufacturers made wild claims about what power of a LED was equivalent to what incandescent bulb, so they sold people 3-4 Watt lights claiming them equal to 60 Watt lights, again, due to a lack of common standards on how to measure it. A common trick was to claim equivalence by luminance (bright light over a narrow angle, won’t light up the entire room). These less powerful lights wouldn’t heat up so much, so they’d last longer.

Perhaps the most visible part of pastoring is the upfront teaching and preaching. Bringing a timely and truthful message demands preparation, knowing Scripture, knowing the audience, and knowing how to connect the one with the other. The articles in this Common Challenge offer in-depth, time-tested advice for addressing the consistent difficulties associated with preaching God’s Word to God’s people.
