Are you in night time? The lights turn off during the day.
Other tips.
• Turn off 'radius estimation'.
• Add a couple of zero to Initial Intensity (make 500 lm = 50000 lm).
• Turn off AutoExposure and make it 80%.

Turn off 'radius estimation' so the light size is only dependent on its intensity.

May I add my vote too please. We're using narrow spots on architectural surfaces any they stop working due to the rendering sphere crop. This needs to be turned off with a yes/no parameter.

vjaramillo has it right, Note Enscape does not do absolute lumin value correctly. For example a wide beam will emit more light than a narrow beam. Even though they are both set at the same lumin value. Each IES file needs to be calibrated separately by eyeballing it....in fact a very narrow beams needs to be X10 or X20 the actual lumin value on the datasheet.

The quick fix solution is to REDUCE extents of the furthermost away geometries.

Can you turn off less important elements, or subcategory of element. For example: Door handles is what we call a 'polygon offender' because the number of polygons it uses is way out of proportion to the small visual field they occupy.

Try seeing what it looks like with all materials which have "Self Illumination" ticked, and make them UNTICKED (in model and family). I puzzled over my model for a long time before trying this and it was like turning the lights on. Self illumination really throws out the exposure settings ... one bad material ruins everything.
