This is a great little light except for the fact that the light will only go on in complete darkness, as per the instructions in bold type. I wanted to use it in a bathroom, however the lack of total darkness and the ambient lighting over my bath tub, even with the shower curtain closed, prevented it from triggering on

I solved this problem by modifying the unit's photocell which is located beneath the semi-transparent dome. Invert the unit on a soft cloth so as not to scratch the lens. Remove the "guts" of the unit by carefully releasing each of the four snap clips, adjacent to the batteries. This in effect removes the exterior case from the batteries and circuit board.

If you examine the circuit board, you will notice two components that sit below the milky dome. One is the circular motion detector and it has a small square window. The other adjacent component is the photocell which detects the ambient light level. It sits closer to the circuit board with a back and forth grid like element on its top.

This photocell must be completely isolated from receiving any light. Using black vinyl electrical tape, I cut small pieces of tape and placed them around the bottom of the photocell to cut off any light passing up through the circuit board and reaching the sensor. I even slid a small piece below the photocell, between its two leads just to be sure. Next I fashioned a small cylinder of tape just large enough to fit around the photocell. After closing off one end, I slid it over the photocell, kind of like a little hat and secured it into place.

Technically the photocell will now present only a small resistance to the circuit even in bright light. Assemble the unit taking care to position the milky dome back over the motion sensor and the photocell.

Mine now triggers on perfectly regardless of the ambient light in the bathroom when I stand in the bathtub to take a shower.

When I moved in to my new house, I was disappointed to find that the master shower was completely enclosed and had NO LIGHTS!! I spent months trying to find a viable, waterproof LED to mount in there, and this fit the bill perfectly. At first, I was skeptical that 1 bulb could provide enough light for an entire shower stall, but this thing is great! I was even able to use double sided exterior mounting tape to fasten it to the ceiling instead of having to drill through my tile. if you are looking for a cheap and easy method to install some lighting in your shower, this is the way to go. 100% satisfied!!

Love these.

I bought 2.

One for my front porch and one for the stairs leading to the basement.

Motion sensor detects movement and turns on just when I need it.

The outside light worked through all kinds of cold and snowy weather all winter.

Sheds good light on the stairway, from the ceiling.

Overall, I think this is a great light. It's extremely bright. It mounts easily to the ceiling and is designed so that it doesn't draw attention to itself. It's easily mistaken for a fire detector. My only wish is that I could adjust the sensitivity. It's perfect if the room is completely dark. However, I've put it in any area that gets a small amount of light and sometimes this ceiling light doesn't come on because it detects existing light.
