Take a look at the advertising graphic. They're trying to let us know that the sensor reacts to motion from as far away as "26 feet."
If the shadowy man (probably an intruder) is six feet tall, the distance shown is fairly close to 26 feet if measured from the light's center to the man's feet. Oops, he has no feet, but you know what I mean.
And if that's right, then the light is 12 feet wide. That's a big light!
Let's take a closer look
Here's the light mounted on a brick wall. A brick (plus a mortar joint) is eight inches across. It's a good construction dimension, and three bricks in a row are almost exactly 24-inches across.
I can count three bricks plus a bit more under the light, so it is about 24" wide. That seems more realistic, but it's still a big ol' light.
Please note there are no intruders brave enough to approach this behemoth.
Shedding some light on this
Here's an actual photo from the Amazon page.
The truth
The actual dimensions for this light are "7.4 x 2.4 x 5.3 inches", making the light's face slightly larger than a dollar bill.
I'm not the only one
As I wrote this blog, an Amazon customer posted this question and received a polite (but cryptic) reply from the seller:
An added-value literary analysis
To me, "lum is the brithness one candel light" sounds like the Jabberwocky poem by Lewis Carroll.
