Very new to blender, first time question. I could not find a similar problem searching existing answers.

I have a rendering, and no matter how many lights or suns I add, this model stays dark. That's a light colored wood texture that appears dark.

This is an imported STL file. It seems like no matter how many lights I add, it stays the same amount of dark. You can see my settings in the next photo. I have a sun, a point light, and spot light all by the model, but no difference weather I turn them on or off.

Thank you for any help.

Wild stab in the dark:

I think you only have mostly reflecting materials in the scene. They act as mirrors and mirrors are only as bright as the stuff they can reflect. You don't have anything bright in your scene to reflect. Just for fun, add a few big planes with diffuse shaders into the scene that are sufficiently lit and see if there's a difference. Alternatively you could crank up the brightness of the world color which, right now, is what gets reflected.

Your lamps seem to work fine since the small areas where they reflect into the camera are burnt white. Problem with mirrors is that they only show the light when the lamp is on the other side of the mirror with matching angles so that it can reflect into the camera. think of where the sun is on a sunset at the beach.

Another way is to use a mix shader (glossy/diffuse). That'll help directing much more light into the camera.
