# Blender 2.80 Cycles light wont render

Download Project - BlenderScene100.blend - Blender 2.80

I was playing around with blender 2.80 when I made the scene above, whenever I render lights just disappear, I can't show you what its supposed to look like as whenever I take a screenshot the lights disappear -

I have no idea why this is happening, any help?

• For future reference, we prefer if .blends are uploaded here. Thanks! – gandalf3 Dec 26 '18 at 13:14

I don't see any problem in your file, except that the light sources are really dim. If you look closely in your screenshot, you can even see a faint reflection. Note that you have volumetric scattering on, which will make things dimmer than they would be otherwise.

Things you can try:

• Increase the emission strength of the spot lamp (a lot, for some reason spot lamps tend to be dimmer).
• Increase the emission strength of the emission shader on Cylinder.001.
• Increase the emission size of the spot lamp. This won't make it brighter, but it will help it converge faster.
• Increase the exposure in Properties > Render > Color Management.
• Huh, that's odd, when I took the screenshot 5 days ago, everything was pitch black, now I can see it. I revoke my question. – Poolie Dec 27 '18 at 4:50

In my case it was the fact, that my light had an animation on it. When I have deleted this animation, everything was fine!
