ResearchTop-emitting deep-UV LED reaches 6.5% wall-plug efficiency
Researchers at Japan's NICT report the first deep-ultraviolet LEDs that emit through the top of the chip, not the substrate. Ring-shaped micro-electrodes and hafnium oxide nanostructures let the 275 nm chip turn up to 6.5% of its electrical input into UV light (wall-plug efficiency), 1.35 times a comparable flip-chip LED, and deliver 38 mW at 200 mA. Published in ACS Photonics, November 2026.

Over 200 Dialight LED luminaires light new Tilbury grain store
Dialight has supplied more than 200 LED luminaires for the new Berth 43 bulk grain store at the Port of Tilbury in Essex, UK, completed in July 2026. Because airborne grain dust can form an explosive atmosphere, the interior is a Zone 22 hazardous area that needs specially certified lighting. Using 78 ProSite floodlights instead of the 110 high bays first planned cut the number of fittings.

EditorialBluetooth NLC to DALI gateway gets test and certification specs
The DALI Alliance has released test and certification specifications for the Bluetooth NLC to DALI gateway. The gateway translates between wired DALI-2 and D4i lighting devices and Bluetooth Networked Lighting Control (NLC), the wireless lighting standard built on Bluetooth Mesh. Wireless systems can then control wired luminaires and read their energy and diagnostic data.
