Tower Panel
What is the mcd intensity of LED on the front of my Dell tower?
What is the intensity of the mcd LED on the front panel my Dell tower? I'm wanting to buy LEDs for a project, but I have no idea of how bright LED to buy. I want to buy an LED 7000 mcd rating, which means nothing to me. I need to know the brightness of the LED on my Dell just had a kind of comparison.
Chuck right – I would say about 15mcd. MDC = milli-candelas. 7000mcd would be considered high intensity. However, for pennies, you can get 20 000 mcd and is more complicated than that. You see them used in advertising displays in stores. They are very catchy and take little or no more power than its Dell (20 m / milliamps (). The previous comment on the angle of post office, are also more effective is fundamentally sound. If this is all new to you, you have to put a resistor in series with the LED. I use a rule base 560 ohms for 5V and 12V 1k. This is almost certainly wrong, but it works (And certainly well below th power of a good size). correct calculations abound on the web. Email me if you want more detail specifications and methods of sufficient strength to the wiring (for example, there are risks with LEDs in parallel, in certain configurations – not all).
