Quick, guess the lighting.

If you said two lights, and use of high-speed sync to get the shallow depth of field, that's a pretty good guess.

If you said zero lights and a rigid high-efficiency reflector, that's an even better (and correct) guess.

When working with an inexperienced assistant — or looking to introduce someone to the world of off-camera lighting — a rigid/high-efficiency reflector is a fantastic and inexpensive place to start.

SolidWorks software helps cut Crenshaw's new product development time and costs in half

Siemens Building Technologies division announced it will acquire Enlighted Inc., a smart IoT building technology provider. The transaction is expected to close in Q3’18.

Enlighted Inc.’s core element is an advanced lighting control application. It is based on a patented, software-defined smart sensor that collects and monitors real-time occupancy, light levels, temperatures and energy usage.

The sensor can gauge temperature, light level, motion, energy, and has Bluetooth connectivity.

The Enlighted system works by collecting temperature, light and motion data via its smart sensors. A gateway device carries the information to Energy Manager, a secure browser-based interface to create profiles and adjust settings of the entire Enlighted Advanced Lighting Control System. The Energy manager operates as an analytics device.

The whole system consists of multi-function sensors, distributed computing, a network, and software applications run by Enlighted Inc.

Enlighted Inc.’s main target market is commercial real estate. Key use cases of its intelligent Lighting Control System are energy efficiency, controlling heating, ventilation and air conditioning, and building utilization reports.

My strongest and most enduring memory of Grand Theft Auto will always be creasing into complete hysterics watching my mate pile into a crumpled police officer with a wooden baseball bat in GTA 3 after school one time. Young’uns these days just don’t appreciate how revolutionary it was to be able to hit a cop with a thing after he’d already fallen over. Suffice it to say I’ve got good memories of the open world series’ nascent forays into 3D, though never enough to tempt me into revisiting them, especially given the poor reception to Grand Theft Auto: The Trilogy - The Definitive Edition. I can sympathise. I’m annoyed just having to type a semicolon and a dash in the same game name.

If you’re in a similarly non-fussed position (I will never not be annoyed that ‘nonplussed’ doesn’t mean what it sounds like it should mean) I can’t imagine a lighting update that’s been available on the mobile versions for a while is enough to tempt you back. But what is a reporter's job if not pathetically treading water between chunklets of Grand Theft Auto news, upon the publishing of which Graham presses the button to release the nutritious pellets on which we all wholly subsist? I hope he doesn’t read that last sentence. I don’t get my pellet if the syntax becomes too convoluted. Moving swiftly on.

Manufacturing solid state lighting (SSL) with light emitting diodes (LEDs) for easy disassembly at end-of-life will facilitate potential end-of-life uses, thereby reducing life cycle costs and environmental impacts, according to a recent study.

Use of environmentally-friendly LED lighting in Europe could play an important role in reducing energy consumption. A new report has now assessed the market for a mass adoption of such light sources, highlighting the need to ensure that the European lighting industry remains competitive.

By using design tools to increase sustainability at every stage of production, researchers have developed a new eco-light. The light, which uses low wattage LEDs and recycled plastic, has a substantially lower environmental impact than the traditional equivalent LED lights.

The economic costs of replacing energy inefficient high-pressure mercury (HPM) lamps, used in outdoor lighting, with more efficient alternatives have been explored in a recent study. High-pressure sodium (HPS) lamps would be more cost effective than light-emitting-diode (LED) technology, although the researchers say LEDs could become more economical in the future.

Insect communities are permanently changed by the presence of street lighting, according to new research. The authors of the study found that predatory and scavenging insects such as ants and ground beetles were more common under streetlights at all times of day, suggesting that light pollution does not simply attract different types of animals at night.

Street lighting reduces the number of moths at ground level and increases flight activity at the level of the lights, shows new research. Less pollen was transported by moths at lit sites in the UK study as a result of the disruptive effects on moth behaviour. The study highlights the need to consider both the direct and indirect ecological impacts of artificial light.

The effect on bats of the replacement of mercury lamps with light-emitting diodes (LEDs) in street lighting has been investigated in a recent study. Artificial light affects bat species differently and the activity of species normally more sensitive to light were affected less by the new LED street lamps than by traditional mercury lamps. Use of LEDs may, therefore, help to reduce the impacts of outdoor lighting on light-sensitive bats, if used at an appropriate level.

The influence of light-emitting diodes (LED) on grassland invertebrate communities has been assessed in a recent study. White LEDs increased the total abundance and changed the species of spiders and beetles recorded. Dimming lights and switching lights off during the middle of the night were the best ways of reducing the effects on beetle and spider numbers.

Researchers use nanofibers to create lights that are more energy-efficient than the common incandescent light bulb, more eco-friendly than a CFL — and they gi
