LEDLM-84PL — LISUN LED Lumen Maintenance & Life Test

The LEDLM-84PL is an LED lumen maintenance and aging life test system designed per IES LM-84 and TM-28 for testing LED luminaires (not individual LEDs — for those use LEDLM-80PL per LM-80 and TM-21). It tests and records optical and electrical maintenance for LED luminaires over time.

The software uses the Arrhenius model and TM-28 to calculate LED luminaire life (L50 and L70 in hours). The system works with GDJW/GW Series High Temperature Chambers and LSP-1KVARC AC Power Source. Can test 8 DUTs simultaneously (more by custom arrangement).

Two solutions: (1) Strict LM-84 testing up to 6000 hours — fully automatic, no manual intervention required; (2) Fast accelerated test using Arrhenius Model to simulate 6000 hours in a shorter time — saves significant testing time.

The LEDLM-80PL (per IES LM-80 and TM-21) is the companion product for single LED and LED module testing.

Standard: IES LM-84 and TM-28 | Test parameters: L70 (time to 70% lumen maintenance), L50 (time to 50% lumen maintenance) | DUTs: 8 per system (expandable by custom) | Requires: GDJW/GW Series High Temperature Chamber; LSP-1KVARC AC Power Source | Life prediction model: Arrhenius | Test duration: up to 6000 hours (or fast accelerated)
