| Description | प्रकाश उत्सर्जक डायोड प्रकाश (Prakāś Utsarjak Ḍāyoḍ Prakash), or LED lighting, represents a modern application of semiconductor materials for illumination, contrasting with traditional *dīpa* (lamps) fueled by *taila* (oil) [1]. The core material is typically Gallium Nitride (GaN), a synthetic compound exhibiting high luminous efficacy (50-200 lm/W) [2]. While absent in ancient Indic architecture due to its recent invention, LEDs offer potential for energy-efficient monument lighting, replacing less sustainable methods. Color temperature ranges from 2700K-6500K, and the Color Rendering Index (CRI) can reach 95 [3]. Durability is a key factor, with lifespans reaching 100,000 hours [4]. Conservation efforts must consider the long-term impact of LED installations on heritage structures, ensuring minimal alteration to the original fabric. Future research could explore integrating bio-luminescent materials, drawing inspiration from natural light sources (*jyoti*) [5], aligning with sustainable practices. The *vastu shastra* principles of light and space can inform the sensitive application of LEDs in historical settings [6].
