Is a 3 watt LED bright?

Is a 3 watt LED bright?

LED bulbs in general are brighter than incandescent lamps and CFLs of the same wattage. A 3-watt LED bulb may produce anywhere between 240 to 320 lumens of illumination. Lumens is a measure of light. A single 3 Watt LED bulb can be equivalent to a 30 Watt fluorescent lamp.

How many LEDs can 3V power?

One 3V Coin Cell Battery can run up to 6 Sewable PCB LEDs or up to 6 leaded LEDs (listed in the link above).

What resistor do I need for 3W LED?

Basics: Picking Resistors for LEDs

Power Supply Voltage LED Color Resistor (calculated)
3 V Red, Yellow, or Yellow-Green 48 Ω
4.5 V Red, Yellow, or Yellow-Green 36 Ω
4.5 V Blue, Green, White, or UV 48 Ω
5 V Blue, Green, White, or UV 68 Ω

What is 3W equivalent to?

For example, a 3W LED is equivalent in output to a 45 W incandescent.

How much current does a 3v LED draw?

For most small LEDs it is about 20mA-25mA.

How many LEDs can I run on 5v power?

Parallel connection allows unlimited number of LEDs with addition of resistors. This is called kirchhoff’s voltage Law. So if you have a 5v power supply and each of your LEDs have a forward voltage drop of 2.4V then you can’t power more than two at a time.
