The specification says this lamp will give 1000 lumens and consume 1.5W.  That works out to 666 lumens per watt.  It has 3 modes.  1.  motion sensor mode that detects movement 2.  Photocell sensing mode that switches on the lamp according to lighting level  3. Normal mode,  allowing the lamp to switch on and off manually.  The light intensity is settable.

Think the supplier has overstated his specifications.  This is because a superbright LED can give only about 100 lumens per watt; normal LED about 80 lumens per watt,  the fluorescent lamp (exclude ballast),  about 50 lumens per watt; incandescent,  about 10 lumens per watt.  660 lumens per watt is not achievable today.  Besides this,  the lamp is not bad for the price except it is not too sure if he has also overstated the other feature.  Hope you can share the performance when you have installed the lamp.
