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.
