400W LED Grow Light Can Replace A 1000W HPS…True or False?

The Extraordinary Importance of Beam Angle and PPFD Uniformity
By Ed Rodriguez | CEO | OptoThermal Technologies, Inc.

In the horticultural lighting industry, there is a common assumption, frequently reflected in product promotional claims, that just about any 2017 model of a 400W LED grow light can do the job of a 1000-watt high pressure sodium (HPS) fixture and therefore offer a dramatic energy saving. Not so fast. Continue reading

Designing More Aesthetic Emergency Lighting Systems

Meeting code requirements for emergency lighting with modern, stylish lighting fixtures

Emergency lighting is mandated by the NFPA and International Building Code (IBC) to ensure sufficient light along the path of egress in the event of a power outage or other emergency.  Although this is typically the domain of electrical engineers, many lighting designers and architects prefer to meet these requirements with aesthetic solutions that fit into the building’s overall design.

The Bright New World of Smarter Automotive Lighting

Rudy Ramos, Mouser Electronics

A friend and I recently went on an evening cycle ride, and because I knew we would be riding in the dark for part of the time, I took my CatEye OptiCube light with me. It was attached to my front handlebars, meaning that when I steered my bicycle around corners, it was always lighting up the section of path or road I was heading toward. Consequently, I always knew what lay ahead. Continue reading

Smarter LED Street Lighting Applications

Jonathan Catchpole, System Architect/Principal Engineer
TE Connectivity

LED Street Lighting is a technology and infrastructure with evolving demands. It is not only about bringing light to an area anymore, it is about anticipating tomorrow’s needs for value added services. Until recently, designers have mostly only been able to select ANSI/NEMA standard product lines, simply because no specific alternative – or even European – standard existed. Now, working with leading industry partners, TE Connectivity has developed a new connectivity solution for LED street lighting, while at the same time creating a standard for European outdoor luminaires.

Why Bluetooth Low Energy Could be the Key to a Smart Lighting Boom

Saara Guastella, Product Marketing Manager
Casambi

Bluetooth Low Energy is a protocol optimized for controlling smart lighting. It overcomes the drawbacks of communication protocols such as ZigBee and Wi-Fi and can be combined with other technologies to make smart lighting even smarter.  Continue reading

2 oz, or Not 2 oz: That is the Question?

Dr Giles Humpston, Applications Manager
Cambridge Nanotherm 

A variation of this question vexed Prince Hamlet while the modern version unsettles many a LED PCB designer. It’s all about copper thickness. When designing a PCB for LEDs, what weight of copper should be specified? Continue reading

LEDs Under the Thumb

Dr Giles Humpston, Applications Manager
Cambridge Nanotherm 

LEDs do two things really well. They emit light and heat, in roughly equal measures. The light is generally useful, the heat less so. Heat and LEDs do not make good bedfellows so when designing a solidstate light source, as much care needs to be taken in removing the heat as managing the photons. Continue reading
