    A:

    It is tricky to comment on a specific installation, I would always suggest giving it a try and they scale it up. What I can do is give you some pointers:

    The LEDs you are looking have a brightness of 1750mCd, it doesn’t equate to candles exactly, but as a ball park estimate 1000mCd is the same as a candle. So the LED is as bright as about two candles. However it isn’t that easy as a candle can be viewed from any direction, but the LED has a viewing of 60 degrees, so may or might not be good at putting the light in the right place for the holes.

    You will need a current limit resistor, see the LED calculator tab on the page of the LED you choose to use to work out the value of the resistor. 8 of these LEDs at 20mA each will use 160mA in total so I’d recommend a power supply otherwise you will be changing the batteries every day. A 5V supply such as:

    Would have more than enough power for the job.
