I bought a motion detector light a few weeks ago. It worked great out of the box, but now its sensitivity has lowered a lot. You need to be really close to it for it to detect motion.

I tried cleaning dust, but it was not dirty.

Is there way to make it more sensitive? If I remove that white plastic that covers the light sensor, will the sensitivity improve?

I know it might make inside electronics dirty, but I don't care about that I can just clean sensor every week.

What kind of motion sensor is this, an outdoor security light, or one for a light switch? Is there an adjustment for sensitivity? What's the ambient temperature, has that changed in the past few weeks, and is the sun hitting the sensor directly? – BMitch Sep 29 '13 at 11:07
Do you have the instruction manual for this light? Typically these lights have some sensitivity adjustment available on them. If not, return it and buy one that does. – Tom Swifty Sep 30 '13 at 17:17
