Light intensity is measured in Kelvin units, which are abbreviated to K.
Will 1000 lumens blind you?
Not at all. Ehhh, definitely won’t blind someone. Maybe mildly irritate them and slightly affect their vision that they couldn’t look directly towards the light but would probably be fine looking a few feet off to the side of where the light is coming from.
