With a backdrop of a 20th anniversary celebration, the featured speakers at Strategies in Light 2019 discussed the history of LEDs, gains the technology might make in the next two decades, how that translates to innovation...
The key things to look out for in a head torch are the brightness (measured in lumens – 300 should be good enough for all but the most adventurous of activities), beam distance (ideally adjustable), a long battery life (essential), weight (the lighter the better), and ease of use (not too fiddly, especially when its cold).
These retrofit units can be tricky to install, but they’re worth it as an upgrade for both cosmetics and lighting intelligence.
A New Level of Comfort From the L grade to the top-of-line Platinum, the 2020 Highlander offers its plushest accommodations ever. Designers took inspiration from luxury crafted interiors to create a more premium ambience. Details include softer padded surfaces and a more tailored look with stitching that continues from the door trim to the instrument panel. The dash integrates the multimedia and HVAC controls in an elegant and functional way.
The rechargeable USB battery doesn’t detract from the power of the lamp itself, which is capable of reaching 330 lumen and shining 75m into the distance. At that brightness (which is plenty), the battery will last for 3.5 hours – not great, compared to the other head torches I reviewed, but then the BioLite has five settings of decreasing brightness, and as you go down in luminosity, you go up in battery life. The lowest setting, 5 lumens, will shine for 40 hours.
According to the spokesperson of the company, their LED high bay UFO light is a high efficiency product, currently available in the LED lighting industry. Available in the shape of a UFO, this bay light comes with the IP65 waterproof rating and is perfect for outdoor applications in the damp and tough environments. The light features high lumen and high heat conductivity. With very low power consumption, the bay UFO light can save a significant amount of energy and has a longer lifespan. The spokesperson reveals that they do not use mercury and other pollutants in their LED light, and thus it is completely environment-friendly. Its pure aluminum heat sink allows a fast and easy heat dissipation, which adds to the longevity and efficiency of the product. The product is suitable for commercial lighting applications, such as supermarkets, shopping malls, parking lots and others.

Make your own LED bulbs, buy the emitters from component supply sites, get name brand supplies (avoid the thrift Chinese/auction sites, fakes, etc). Run the emitters at 1/3rd the current that the bulb makers do. Build a decent buck/boost driver for them. Use a good heat sink. As an extra bonus, they will be twice as power efficient as the premade ones (check the spec sheets, they may list lumens/watt at low current). Enjoy your efficient long lasting light for the rest of your life, or until it is zapped by a thunderstorm, dropped, or something better comes along.
To consolidate building controls over a single management ecosystem, you need to be able to accommodate multiple building management protocols. Bluetooth Mesh is an ideal communication standard since it can handle data transmissions of virtually any type. However, when you start mixing and matching system protocols, you need a common language that enables device interoperability. For example, DALI (digital addressable lighting interface)yebdqxvrcsvyzfsexcbyceux has long been the standard for lighting dimming controls, but you need a BAS protocol such as BACnet to manage HVAC controls. If you are going to use the same interface for both systems, you must find a common approach to make them interoperable.

“I love to travel light and fast when I’m adventuring in the great outdoors. I use the Petzl Bindi head torch. It weighs virtually nothing – just 35g – so I barely notice it being in my pack (£32.95 - £67.00, Amazon). But it can still produce 200 lumens of light, so it’s bright enough for all of my needs: whether I’m wild camping high in the Lake District fells, finishing a hike in Snowdonia after dark, or simply reading in a Scottish bothy. There are loads of other excellent features. USB charging means I can boost the battery out in the hills using with my portable power bank, rather than fiddling around with spare AAA batteries, while the one–lumen, red-light ‘proximity’ mode is great for reading without draining charge. The strap is comfortable and easily-adjustable, and the head torch looks good too. But best of all is the price. At just £35 on some websites, the Petzl Bindi is a stone cold bargain – and that means more money to spend on your adventures.”
According to a study conducted by the National Association of Realtors, 91% of homeowners surveyed have a greater desire to be home and have an increased sense of enjoyment when they are there after completing a kitchen renovation. But that doesn't mean breaking the bank. Simply lighting the existing kitchen properly will add depth and dimension while creating the illusion of taller ceilings and larger work spaces. Have your electrical contractor install LED under cabinet lighting to provide useful illumination for completing everyday tasks. Interior cabinet and above cabinet lighting help to elongate the ceiling and spotlight decorative items, while toe kick lighting creates the illusion of floating cabinets.
