TC- Temperature Control
The series of SMART LED GU10 retrofit globes feature a special IC (integrated circuit) which allows the SMART GU10 globe to adapt itself to the luminaire and ambient temperature to manage the heat of the globe, improving performance and maximising efficiency.
If there is a heat build up inside the the luminaire the thermally controlled IC reduces the power to protect the LED itself.
The slight reduction in output is barely perceptable.
These globes are of a COB (chip on board) construction mounted behind a lens, giving excellent light control.
