Hello Doug,

I finally ran the tests on my Nexus with FF Beta and for:

Light: 42 pass and 3 Fail.  3 Fail are with value of undefined resolves to NaN, expected type error. I haven't dig into these errors yet.

Proximity: 81 pass and 2 Not Run.  2 Not Run are with User Proximity.

Please find my comments:

1. I would suggest to change the title to "Ambient Light Events"

Happy to change the title of the spec.  The event names will remain the same.

2. Section 5.2:

         - Computing "lighting condition" (such as warm day, pitch dark etc...) from light value is non-trivial. Ligting condition corresponds to logarithm of Luminance. Therefore, it is better "lighting condition" parameter is added to the Light event.

        - If it is not acceptable (as this information is redundant),  as an alternate, a note could be appended at the end explaining how the lighting condition could be arrived from the light value

What language would you use as a note to describe how the lighting condition can be derived?

3. Section 5.2.1

         - the unit of the value should be specified


4.  Section 5.2.2

           - For all practical purposes, I beleive, the developer would be interested in events only when the lighting condition changes. Therefore, light event should be fired only when "lighting condition" changes. I have not tested the latest Firefox implementation on mobile. Could someone please let me know how often does it fire the event?
We fire when there is a change.  The UA determines when there is a significant change.
