The best distance of illumination for LED spotlights
The spot distance of a LED spotlight depends on its luminous angle. The power is not very large.
Each manufacturer, brand LED spot light effect is not the same. The simple point is that some are good and others are bad. You want to give a brand what ah, or so many LED spotlights.
The distance of irradiation should be above 50CM, and 100CM--280CM is the best distance.
