I’ve been experimenting with high-power LEDs in open, non-commercial setups to better understand real-world thermal behavior outside finished products.
What stood out was how strongly non-electrical details affected stability:
– mounting pressure
– interface materials
– real airflow paths versus assumed ones
Electrically everything stayed within ratings, but long-term thermal behavior varied more than expected.
For those who’ve worked with power-dense hardware:
what thermal assumptions turned out to be wrong in practice?
