I have done research in this case.
Start with a candle.
Here is a quote:
"It's very simple. Get a birthday cake candle. Take a ruler. Stick a candle at one end of the rule. The lighted candle. Turn off the lights. Sing happy birthday doc. It was his 47 23. in OK , stillness. nonsense. A foot-candle of light is the amount of light that birthday cake candle generates one foot. "
"A candle is a unit of light. The light is measured the same way. Remember, a light is turned off, how bright the light is one foot from the source. The light is a measure of the amount of light to attain what You light! want to light, is equal to one foot-candle falling on one square meter. "
"So, if the candle and ruler, we can place a book at the opposite end of the candle. We would be a little light when you get the book next to the candle, you know. If this book is one foot by one foot one foot is square. OK, managed to make mathsRight now doing all the light on the book, with one foot out of your candle, both ... ... 1 candle holder and light! "
A light 3 light corresponds to three birthday candles shining on something that is square meters, with one foot.
You can read everything, from where I made myself on this link:

It seems a strong light source, but in a dark basement that works better than a candle.
