I like the idea and hope you sell a million. My critique .....
What size is it? What type of batteries does it use, and approximately how long will they last under normal use, if you can determine what normal use is.
And you should try to take some night shots with the product in place so it not only shows approximately how much light it throws off, but how well it blends with varied decor or how inobtrusive it is because of its size or design ..... etc. As with any product, you need to "sell it" not just show it.
So far as the price point is concerned, you`re in Sharper Image territory at $25 for a night light, so you`d do well to look through their catalog and site to see how they sell/show things.
Again, best of luck.
