Camera headlamp intensity breaks "preview lights" ?

Made a scene, set my view to my camera. Texture shaded.

Headlight is off. I can toggle preview lights (CTRL+L).

I turn on the headlamp. Preview lights doesn't do anything noticeable.

I set the intensity of the headlamp to 0, or any other non-default value. Scene goes black (with a low value obviously). Preview lights doesn't do anything.

Leaving the intensity low, I turn the headlight off. Preview lights still doesn't do anything.

Changing from the camera view to perspective makes the scene full-bright regardless of the Preview lights setting.

Shouldn't the preview lights toggle scene full-bright regardless of a camera's headlamp intensity setting and current view ?

    I'm not quite clear what you are doing - when preview Lights is on (the default) you see an attempt to show how the render lights will seem, when off the headlamp is used. If the headlamp is On it will show in the render and so be part of the lighting being previewed.

    I don't really understand what you're saying either. You're saying is if preview Lights is on, the lights are shown. If the preview light is off, the headlamp is shown ? Why would turning off preview lights show the headlamp ?

    I'm trying to have a headlamp with a very low intensity. But when I set the intensity, the whole scene goes black, and Preview Lights doesn't do anything. Turning off preview lights should stop previewing lights. So everything should be visible, right ?

    File a bug report, because it seems broken.

    I was just playing around with it and yes, headlamp off, made the scene dark, then toggling the preview worked as expected.  Changed the intensity to half, still worked as expected.  Dropped it to less than half...quit working.

    Preview lights off is using the headlight - that's what it is for, so you can get light into the work area if the lights are too dim or wrongly placed to let you see what you are doing. However, the intensity issue does sound as if there's an issue.

    It works fine until it drops to less than half strength...

    The headlamp isn't meant to be a part of your scene lighting, it is to provide light to work by when no other lights are set.  There is no reason to be messing with its intensity.

    Those 2 first statements contradict each other. If a scene has poor lighting, turning off "Preview Lights" is the go-to function to work in a full-bright environement. Not turning on the headlamp. The headlamp actually appears in renders for 3Delight and Iray.

    The headlamp can, if the user chooses, be used in render lighting. It has been given enhanced settings recently to make it more useful for that.

    Support has replied to my ticket saying it's indeed a bug and a bug report has been filed.
