We can deduce the energy stored in the capacitor expressed in Watts
How to power LED with 120 volt A/C supply
I hope you used a big enough resister - probably a 1 watt minimum. I calc your circuit is about 5 mA, so the resister is dropping 120v * .005 = .6 watt. If you were using a smaller resister and running the lead at the usual brightness and current (20ma) then you''d drop 120v * .02 = 2.4 watts. That''s probably a good way to fry your circuit board.

How many MF can a capacitor give a LED light?
Edit: by the way, your capacitor is almost certainly 150mF, which will give you 1/1000 of that, or a few seconds. (For easy illumination of a white LED, try 3 NiMH AA batteries, which give you almost exactly the right voltage)
Which capacitor should be used for LED lighting?
A typical LED lighting circuit is shown in figure 1. For C1, C2, and C3 safety recognised capacitors should be selected that are rated AC 250Vrms. C6 is the snubber capacitor for the diode; parts rated to withstand DC 250V to DC 630V are needed and these can have X7R temperature characteristic.
How long does it take to connect a capacitor to a led?
The direct answer to your question, assuming you intend to just connect the capacitor to the LED with a series resistor is no time at all. That is because a white LED takes more than 2.7 V to light. Check its datasheet. These things usually need a bit over 3 V. There are two options. The simplest is to use a LED with a lower forward drop.
How many volts a capacitor should I use?
Some places recommend using 450uf 25V while others 1000uf 35V. Can someone explain in short what is the factors taking into account when choosing the capacitor value? My Setup OR In this case should it matter that the first power source is 12V ? where should I install the CAP? Thanks
How many Watts Does a 6 farad capacitor need?
You need something like 7.5 Watts for 10 seconds which is 75 Watt seconds or 75 Joules. Starting with a 5 volt charge that would imply a 6 Farad capacitor assuming all the energy can be extracted from the capacitor which probably isn't practical for the reasons noted in the previous posts.
Should ceramic capacitors be used in LED lighting circuits?
Overall, the conditions experienced by ceramic capacitors in LED lighting circuits should not be underestimated. It is my experience that selecting the wrong capacitor can adversely affect the lifetime of the end product due to crack formation in the dielectric material of these capacitors.
