How are you?
Trying to render an element to which I have configured to emit light, looks black as you can see in the attached image,
What would be the correct settings to achieve the desired result?
Sorry for my bad English.

The problem will be that although the object emits x-number of watts, the power is spread out over an area of several square meters -- for a more extreme example, imagine if the box were the size of a football field, instead. Assuming the desired result to be for this large box to shine as brightly as a small light bulb, the emitter wattage would need to be something on the order of a hundred-thousand watts (using the default efficacy of 12.7).

You're right, make the adjustments and now if I see results. Thank you very much for the prompt reply!
