Lab-scale perovskite LEDs with >25% EQE and tunable color; no commercial product or architectural deployment.

Metal-halide perovskite light-emitting diodes confine charge carriers to achieve narrow-linewidth, color-tunable visible light emission across red, green, and blue spectra. The technology targets applications requiring compact, spectrum-selectable solid-state lighting. Current state: best-in-class performance metrics (>25% EQE, 12,500-hour lifetime) are consolidated from independent lab studies, not unified commercial devices; architectural integration remains undemonstrated.

Metal-halide perovskite LEDs offer something the mature LED market cannot yet easily match: compositionally tunable, narrow-linewidth emission across the full visible spectrum without phosphor conversion losses, with lab-measured external quantum efficiency above 25% — competitive on efficiency alone with commercial inorganic devices. The 12,500-hour lifetime figure comes from consolidated independent lab studies, not a unified commercial product, and that distinction matters enormously: real-world building HVAC stresses — thermal cycling, moisture, UV — remain entirely uncharacterised against these devices. The structural problem is lead content, which creates both a regulatory and environmental barrier that has no clear mitigation pathway at building scale; ion migration under operating stress causes colour drift and efficiency degradation that encapsulation partially addresses but does not solve. Scaling from millimetre-square lab specimens to building-panel areas is undemonstrated and may not be economically feasible at the yield rates current fabrication can sustain. For a design team, perovskite LEDs are an emerging technology worth monitoring for specialist spectral applications — display, horticulture, tunable task lighting — but the combination of lead toxicity, unresolved lifetime data, and zero architectural deployment means this is research-phase material, not a specification candidate.

Source is a peer-reviewed 2025 RSC literature review, not primary research or product datasheet. The >25% EQE and 12,500-hour T50 lifetime are credible but cherry-picked from separate studies; no single device meets both specs simultaneously. The architectural lighting application is a forward projection by authors, not evidence of any pilot, product, or real-world deployment. Ion migration and lead leakage are well-documented degradation mechanisms in perovskite literature but not solved. The source URL page excerpt is navigation/analytics boilerplate, not substantive content—full article text was not provided. No commercial timeline, regulatory pathway, or scale-up feasibility data available.
