Hubbell Lighting ComponentsELGIN, Ill., Nov. 19, 2015 — The FSP3-480-20kA surge protector from Thomas Research Products protects LED luminaires on 480-V circuits from surges up to 20,000 A. Inline fusing shuts down the luminaire when the capabilities of the surge protector have been exceeded. An LED indicator displays functioning, advancing luminaire protection and making it easier to diagnose issues. Applications include street lighting, big-box retail, warehouses, parking garages and transportation facilities.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/27/2023LED Panel IndicatorsThe PTx470 series of direct incandescent-replacement LED panel indicators from LEDtronics Inc. is designed for front mounting, bolt-in, and non-relampable applications in industrial controls and...Photonics Spectra May 2024 IssuePIN PhotodiodeThe VEMD2704 from Vishay Intertechnology is a silicon PIN photodiode that can be used with green LEDs for optical heart rate detection and red LEDs for pulse oximetry applications.
