Netatmo Presence review: This security camera justifies its price tag | Intelligent Control Led Emergency Bulb

Cree's Connected Soft White LED light bulb isn't the prettiest lighting fixture, and it can't change colors like some other LED bulbs, but it's smart and it's inexpensive to acquire and operate.

Toyota introduced its new 2020 Highlander at the New York International Auto Show this week. There's plenty for Highlander fans to get excited about, but there's also a treat for Android nerds: the SUV comes with Android Auto compatibility standard.

Funny how my directly heated triodes and rectifiers from the 1920s have filaments that continue to be reliable and light up today. Similar tech but different ‘needs’.

The breadth of the program at Strategies in Light 2019 was truly amazing. You can get some idea of that range in the article covering featured speakers in this issue.

It was the most comfortable of all, partly because the battery sits at the back of your head, balancing the weight of the light strapped to your forehead. I found the slim design (9mm) sat comfortably flat and securely on my forehead without digging in, and the straps were easily adjustable for a snug fit.

Let's call these spaces what they are: flaw accentuation chambers. Lighted to your worst advantage. It doesn't matter if you're a supermodel.

FIG. 2. Specialty LED drivers and control modules can be designed to provide additional programmability to connected emergency lighting and building systems for features such as remote maintenance and monitoring, dimming, power metering, data collection, commissioning, and more.

Second, the only LED lights I’ve seen in the last decade with stroboscopic flicker are cheap Christmas lights (unless you’re running an LED bulb on an unsuitable dimmer). I’m extremely sensitive to LED flicker – I can see it in some car taillights, LED Christmas lights, cheap flashlights, and in magnetic-ballasted fluorescents. I cannot see flicker in modern LED bulbs.

With the meteoric rise in LED lighting, look for fluorescent lighting to become obsolete for most of its previous uses. LEDs are lighter, more versatile, cheaper and provide vibrant illumination.

The cranberry company has already used LED luminaires embedded with wireless sensors to slash energy costs. Now it wants to use the lights for other purposes, like tracking assets including people, ladders, and forklifts. ...

Seoul’s Acrich NanoDriver Series devices, made with this patented technology, was named as a winner in the Sapphire Award category “ICs & Electronic Components for Solid State Lighting.” By virtue of its continuous technology innovations, Seoul owns over 250 patents concerning LED driver technology around the world.

The edge-lit luminaire has an embedded honeycomb lens light guide that produces even illumination while reducing glare. Surf offers both general lighting and visual comfort, not typically found in surface-mounted units.
