The council replaced the warm halogen bulb streetlights in our area with extremely bright LEDs that have no shielding towards houses. I slept in a ground floor bedroom with a bay window directly beneath such a light for a year. Despite installing blackout blinds as best I could, the ambient light in my room was about the same level as mid-dawn the entire time. My mental health suffered intensely almost to the point of psychosis.
LED lighting should be tightly regulated. At the moment they just appear to be getting brighter and brighter and more prevalent. I absolutely despise them.
It sometimes helps to call the council about this. Many streetlamps have the option for shading in certain directions to prevent your problem, but the guys installing it might not set it correctly.
My parents had the exact problem. Called up the city and actually a few days later a cherry picker appeared and there was no more light glaring into their windows.
