I am new to blender. I am trying to change the light strength on multiple lights. I cannot figure how to change them all at once. I see how to change objects, but not lights. Any tips out there?

Select all your lights, go into the Object Data panel, type the new Power value (or Strength for the Sun) and AltEnter. Or select all your lights, select the one you want to copy the strength from at last, and right click on its Power value > Copy to Selected.

  • $\begingroup$ Thank you for the reply. That is exactly what I was looking for. I did see the "Adjust Light Power" when I select all the lights and right click, but I see it adjust the lights from where they are initially set by the increase you change that selection to, but the change is only made by moving the mouse. I don't see where a keyboard input can be made with that option. $\endgroup$ Apr 11 at 18:33

  • $\begingroup$ @Georgenikas where there's a slider that shows numbers you can either drag with the mouse or click on the number and type in a new value. Does that help? $\endgroup$ Apr 11 at 19:37
  • $\begingroup$ oh ok yes you need to type the value then Alt Enter, don't use the left or roght arrows to adjust the values $\endgroup$

  • $\begingroup$ I just figured out how to use "Custom Properties" and add all my lights to that Custom Property and adjust them all at one time. I realize this is good only if I want a group of lights to have the same power. I was also able to use the "Custom Properties" to change all the light colors at the same time with one entry. $\endgroup$ Apr 12 at 19:20
