## Most critical reviews (4 lowest-rated)

### 1/5 — Of no intrinsic value

*2015-10-19*

Any lighting designer would find this pretty pointless.
Sorry, but it's based on the performance of some arbitrary luminaire so how that relates to a user's actual requirement is questionable, as is the likelihood that the user will know the required information and be seeking the result the app gives. It's more likely that the user will need to know how many luminaires would be required to meet a given light level, and it would be preferable for the user to be able to load a specific luminaire's photo metric file.
Lastly, check out your LPD calculation formula, because it's just plain wrong.

### 1/5 — Does not work

*2015-09-18, version 1.1*

Maybe I'm missing something. It doesn't seem like this app does anything. I put in all the numbers and the calculation never changes

### 1/5 — No FC given?

*2015-06-03, version 1.1*

Would not give an output for footcandles.  I tried several design types. Not sure what is wrong.

### 5/5 — Save button

*2014-07-19, version 1.0*

You need to press the save bottom above the keyboard in order to get final results.
