What is the current of a red LED?
Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.
What does red mean on LED light?
A red and solid LED indicates that the battery of your Motion is low. The remaining battery is under 10%. A red and blinking LED indicates that the sensor is recording, but the battery is low.
What is the price of one LED?

How much current can a red LED take?
A must have for power indication, pin status, opto-electronic sensors, and fun blinky displays. This is a very basic 5mm LED with a red lens. It has a typical forward voltage of 2.0V and a rated forward current of 20mA.
WHAT LED forward current?
The forward current of an LED, IF, is the current which flows across the LED’s leads, from anode to cathode, in order for the LED to receive sufficient current to power on. As you can see above, positive voltage must be applied across the LED from its anode to its cathode.
How much current does A 3mm LED use?
18mA

What are red LEDS used for?
Red light therapy (RLT) is a controversial therapeutic technique that uses red low-level wavelengths of light to treat skin issues, such as wrinkles, scars, and persistent wounds, among other conditions. In the early 1990s, RLT was used by scientists to help grow plants in space.
What each LED color means?
The lower the number, the more reddish or warmer the light. The higher the number, the more bluish or cooler the light. When we’re talking about the color of an LED light, especially in residential lighting, we’re really discussing two things… White lights and RGB (red, green, blue) lights.
Which bulb is good for eyes?
Traditional incandescent bulbs are fine, but many people are looking for a more energy efficient option. Luckily, “warm light” CFLs (Compact Fluorescent Lights) are okay for your eyes, as well as being much more efficient. They do emit UV rays, but a much smaller amount. You can also use LED bulbs or halogens.
