7 Disadvantages Of Led Lights

1. Blue hazard: There is a concern that blue LEDs and cool-white LEDs are now capable of exceeding safe limits of the so-called blue-light hazard as defined in eye safety specifications. 2. On an initial capital cost basis, LEDs are currently more expensive, measured in price per lumen, than more conventional lighting technologies.  3. Over-driving the LED or not engineering the product to manage heat in high ambient temperatures may result in overheating of the LED package, eventually leading to device failure.  4. Voltage sensitivity: LEDs must be supplied with the voltage above the threshold and a current below the rating. This can involve series resistors or current-regulated power supplies.  5. Area light source: LEDs do not approximate a “point source” of light, but rather a Lambertian distribution. So LEDs are difficult to use in applications requiring a spherical light field. 6. Two different white LED will have two different color characteristics, which affect how the light is perceived.
