Luminis Supports Lighting Design for LEED-certified Building in Quebec | High Lumen Led Floodlight

But when it comes to the LEDs themselves, there is more to lifetime estimates than predicting catastrophic failure.

Facinating article. I knew they limited the lifespan of products in order to keep prices down and the consumer buying more often – but that was for household appliences, not simple lightbulbs! I don’t know much about the intricate technical issues at hand, but I had new ceiling lighting put into an old house I bought just over a year ago; out of 38 recessed LED trim lights I have (I think 60watt equivalent) only 1 started the deathly flicker after 1 year. All are (apparently) dimable but I did not install dimable switches. I probably used that bulb (1 of 4) for about 2000hrs a year. Additionally, a 40watt equivalent loose ‘globe’ LED bulb I have also just started flickering, probably after similar 200hrs. I am definitely more educated now when looking to purchase replacements. Thanks.

The Peloton is reportedly the first linear high bay luminaire in its class to test and certify to the UL 924 emergency lighting standard. This standard mandates that the luminaire must meet minimum lighting levels and feature overriding controls in emergency mode to light the path of egress in the event of an emergency, thereby increasing the safety of occupants.

In my experience, a lot of LED bulbs last MUCH shorter than even 1000 hours. More like 100-200 hours. But I haven’t found a pattern, it’s not that the cheaper ones die sooner.

Replacing the bath light fixture, I reversed it, (Bulbs facing up) allowing the new LED bulbs to run cooler, and soften the light as it bounced off the ceiling. So far, pleased with the mod.

Let’s start by considering how an extended intelligent emergency luminaire ecosystem can improve building safety. Sensors in emergency lighting units can be programmed to detect hazardous conditions as well as to facilitate a safe exit. For example, sensors can be programmed to detect fire, smoke, carbon monoxide, even the sound of gunshots. Once a hazard is detected, the sensor can trigger a programmed response, such as alarms, emergency lights, and even a signal to emergency services.

I recently did a lighting changeover in an apartment building, from CFL to LED. Current draw went from 300-350ma to 125ma per bulb. We found that by upgrading from 3000k to a 4000k brightness bulb had a slightly higher cost, we could lower that current draw down to 75ma. Spread over 250 bulbs in the building we calculated our power bill will drop by 2/3rds. The 30,000 hour bulbs are guaranteed for minimum of 3 years.

Special, easy-to-use hybrid tech adds an element of control and fun. Using a sequential shifting feature, the driver can “downshift” to increase the regenerative braking in steps, which fosters greater control when driving in hilly areas, for example.

The Philips Hue Outdoor Motion Sensor is a must-have accessory for homeowners using Philips Hue smart lighting products.

Incandescents aren’t recyclable. LEDs are repairable, although I haven’t had any die yet. I take CFLs apart, recycle the tubes, and repurpose the electronics. The inductors are good usually.

Wherever possible, Hyundai took the opportunity to combine a technological development with visual or space benefit. The new Shift by Wire (SBW) gear selector is a prime example, as the new interface not only is sleek and technologically advanced but also takes up significantly less space than a traditional gear selector.
