Renderotica

Try this, it's a set of four emissive lights arranged in a semi-circle. Very simple yet quite effective. I use it in almost every render I do since I learned about emissive lighting. 

 

 

If you are using perspective lens for rendering, it is all down to general lighting. If using camera, try changing aperture (large number, small hole, better sharpness, less light) or switching on the headlight. If indoors, and roof not visible, switch it off and using external light. Use spotlights and pointlights and distant light. With spotlights view through them to see where they point, but you must use camera or perspective to render. Light levels normally need to be high - Spotlight, parameters, light, photometrics, luminous flux. I often need levels with several zeroes, eg 150000 lumens. Try postwork - may be able to raise brightness in a photo program.
Look at https://www.renderotica..../Shape-of-Things-to-Come where I used a range of different techniques such as above. Narrow spotlight spread to focus on small area, for exampele.
