which works better, LED or incandescent lights? Answered


Depends on the application:

Pro: intense colors, high efficiency, switch on and off very quickly, tiny, long bulb life, low voltage requirements to turn on, and rugged.

Con: Work poorly with AC power, white LEDs are less efficient than pure colors, requires many to make something really bright, linear output is, only conduct in one polarity, dependent on current through them.

Pro: Easy to control, easy to install, are available in a huge variety of styles and brightness, you can get them upwards of 2000W.

Cons: Poor efficiency, difficult to get bright ones at low voltages, short life relative to LED, easily broken, noticeable delay to turn on and turn off, usually run hot

Incandescents are better for heat and light, and things like thermal car-indicator circuits, mains light dimmer switches. Also if you're using a light source for spectroscopic analysis (e,g IR / visible), you need a broad-spectrum source - LEDs will not do.

Well there's an open-ended question!

I'd say the most conventional light in the existence of the planet, our very own sun, works the best.

true, how true. i changed it....that more narrowed for u?

An LED is more efficient, but incandescent typically produces a more pleasant light (ie. closer to full-spectrum sunlight).  I suppose it all depends on what you're illuminating, and what your power source is.

An LED is more efficient than a conventional incandescent.

It depends, for what purpose do you want to use it and your personal preferences? 
Under certain specific circumstances, an LED, an incandescent light, fluorescent light, a  carbon arc, or whale oil torch may work better, depending on the need.
