The Long Journey to FEMA’s Presidential Alert Test | Led Ceiling Light Fixtures

LIFX’s pint-size bulb arrives in a non-tunable, white-only model, but drops a ton of features along the way.

The global hazardous location LED lighting market was valued at USD 309.81 million in 2017, and is expected to reach USD 585.19 million by 2023, registering a CAGR of 11.17%, over the forecast period of 2018-2023. The scope of the report is limited to solutions offered by various players, including providers of cart light, flash light, and flood light LEDs.

I’ve seen lumen depreciation and color shift first-hand. In June of 2010, I replaced twelve 65W incandescent PAR30 floodlight bulbs in our kitchen with LED equivalents. At the same time, I also replaced three lights in another room with identical LED bulbs. These three bulbs see much less use, so in preparation for this article, I took one bulb from each location and put them side-by-side to see if I could tell the difference in output. The recessed light fixtures in both rooms are identical, so I expect that the bulbs are exposed to similar temperatures when on: any difference should only be due to aging effects. The results were shocking. Since these two bulbs were in different rooms, I never saw them side-by-side, so didn’t notice how bad the lumen depreciation and color shift had become. Sure, I knew they were dimmer and yellower than when I installed them, but had no idea it was this bad.

Blue OLEDs are not much better, the compound used is IIRC an anthracene derivative and it burns. You can actually get a display from an old phone and see how often they keyboard has been used!

I opted for the teal blue, but it’s also available in grey, orange and red. It wins points from me for style, too, and wouldn’t look out of place either at a festival or on a mountain. Plus, it packs away very small, and can be turned into a hanging lamp when conjoined with BioLite’s light diffusing stuff sack. Ingenious.

The two companies are targeting the architectural lighting market. Meanwhile, OLEDWorks also teams up with Audi.

This also applies to entrance areas and parking garages as LEDVANCE now offers lighting professionals more products for the lighting of these areas: The Downlight Alu DALI family has been extended with a 14W version for a cut-out diameter of 150 mm in the color temperatures 3,000, 4,000 and 6,500 K.

In addition to Safety Shield 360, the 2019 Maxima also expands the availability of Intelligent Cruise Control (ICC), High Beam Assist (HBA) and Traffic Sign Recognition (TSR).

Kendall Chatter hanged himself Nov. 25, 2018 in a cell in the temporary holding unit at Staton prison, using a sheet tied to the ceiling. He was “intensely yelling and banging on his cell in the immediate lead-up to his suicide,” the order stated. The correctional shift supervisor told an officer to allow him to continue until he got tired and stopped. That supervisor was later reprimanded. Earlier that month, Chatter cut his right wrist, possibly after being sexually assaulted.

Fulham Co., Inc., a supplier of lighting components and electronics for commercial and specialty applications, has expanded its HotSpot line with a new category of value-added emergency lighting products that extend building safety lighting.
