• Ingantaccen Ingancin Launi:Haɓaka phosphors da mafita na guntu da yawa don cimma mafi girman ƙimar CRI da mafi daidaiton bayyana launi.
• Ƙananan Girma:Haɓaka ƙananan, amma masu ƙarfi, LED na guntu-guntu (CSP) don aikace-aikacen da ke da ƙarancin sarari.
• Hasken Wayo da Haɗin kai:Haɗa na'urorin lantarki na sarrafawa da ka'idojin sadarwa (DALI, Zigbee) kai tsaye cikin ƙungiyoyin LED.
• Musamman Spectra:LED waɗanda aka keɓance don hasken noma (haɓaka girma shuka), hasken mai da hankali ga ɗan adam (kwaikwayon yanayin hasken rana na halitta), da aikace-aikacen likita.
