The answer to 'lighting installation gets hot' is that a lighting fixture getting hot can be caused by several common issues, including improper wiring, a faulty light bulb, or inadequate ventilation. Symptoms may include the light fixture feeling very warm to the touch, flickering or dimming lights, and in some cases, a burning smell.
If the issue is caused by a faulty bulb or inadequate ventilation, this may be a simple DIY fix. However, if the problem is due to wiring issues or other electrical problems, it's best to call a licensed electrician to diagnose and resolve the issue safely.
