It seems that no matter what I set the parameters too, the pulse lights...they do nohting.
Either in the CK or in a test cell in game, new custom or even provided lights...
I read the wiki, searched the GECK guides, searched the GECK forums, searched the Skyrim forums...the forums, they do nothing.

Flicker lights work fine. Adjusting the parameters while the light sim is running makes the CK a little unhappy, but they work.

Or maybe I don't know what a pulse light is...I think it's a light that grows and diminishes in intensity evenly, and that a flicker light includes random jumps in intensity based on the provided parameters.

So far, I think that setting Period to 6 should cause the light to fade from the minimum intensity to the set intensity in 6 seconds. Setting the intensity amplitude reduces the initial intensity of the light by the amount set. Setting a higher intensity amplitude that the initial value kills the light. Setting it to an equal or lower amount from 0.001 does nothing to the light.

Wiki mentions a color amplitutde, but there is no such setting.

Fade appears to be the value that you adust with ctr-alt-s in the render window.

Setting the light as omni, omnishadow, spot, or spot shadow has no effect.

http://www.creationkit.com/File:Lightpulsefunc.png doesn't make any sense. Creating a light with an intensity amplitude of 10 and a period of 6.28 should give a light with a fade value of 10 should create a cycle that goes from full bright in a 12x12 room to full dark according to that graph.

It does nothing. It doesn't move at all.

Bump.

Probably just another CK function that does not work at all.

Can confirm the Pulse function it just does nothing. Use flocker and change the light stats.
