Frequently asked questions
A typical 0.5W white SMD LED voltage is usually around 3.2V. While a 0.2W one uses approximately 3V. It is important to note the different categories of LEDs that relate to the power Supply output they can provide.
First, you can perform a Very simple flicker test with your smartphone camera. Turn it on and aim it at the lighting source in question while looking at the image captured on the screen.
That means this is an LED Chip (device) mounted directly to a light set strip, without using wires cable. This surface mounting technology is indeed what makes LED Light set Strips possible.
A series resistor is required to control the LED current flow. Three white LEDs add up to about 9V, so 3V will be dropped across the resistance so they can operate from a 12V Power supply.
Lumex's Low Current SMT/SMD LEDs are the best solutions for low-power consumption applications. The operating current of Lumex's Low Current SMT/SMD LED.
