Is it true that overdriven LEDs are brighter?
It is true that an overdriven LED will be brighter, but the return from increased power diminishes the further you go. For example, if your bulb is rated for 200 mA, and you drive the LED at 400 mA using a constant current driver, you will not receive twice the lumen output.
Which is better LED light panel or speedlight flash?
This is because the LED Light panel has a much larger surface area that the light is output over. The LED light panel was also using a diffusion panel in front of the LEDs rather than bare LEDs. You can easily get a more diffused light from a speedlight flash by using a diffuser of some sort.
How are over and under driven LEDs controlled?
Over- and under-driven LEDs are controlled by the drivers associated with them. This is why you typically see this as an issue with low voltage (12- or 24-volt) LED lamps. The driver regulates either the current or the voltage being delivered to the LEDs.
Which is bigger a hot shoe flash or an LED light panel?
However, as you can see below, even a small 160 LED panel is larger than a speedlight flash. There are also many hot shoe flash units available that are smaller than the SB800 used for the example above.
How does the current in a LED circuit work?
Electrical current (the rate at which electricity flows in a circuit) controls just how much wattage is being used by the LED and how bright, or active, that LED chip is. Changes in this electrical current, above or below the optimal driving current, can lead to underdriving or overdriving of the LED.
Why does my led have too much current?
This is why you typically see this as an issue with low voltage (12- or 24-volt) LED lamps. The driver regulates either the current or the voltage being delivered to the LEDs. Using the wrong driver can deliver either too much current or too little, leading to one of these two driving states.
