When The Power Is Turned On For The First Time, The Bulb Will Keep On For 3 Seconds Regardless Of Night Or Day. It Goes Out After 3 Seconds And Enters The Normal Working State. After That, The Bulb Is Ready To Work. If Ambient Lighting Is Bright, The Bulb Will Remain Off And Will Not Respond To Movement Until Dark.

If The Ambient Light Is Very Low (Below 6 Lux), The Bulb Will Turn On And Stay On As Long As There Is Movement In The Sensor Area. The Bulb Will Automatically Turn Off 30 Seconds After The Movement Has Stopped In The Area Of The Motion Sensor. Faq: Q: Why Does The Bulb Not Turn Off Or Turn On By Itself?

Answer: These Bulbs Are Equipped With A Very Sensitive Motion Sensor That Reacts To Any Movement. The Triggering Of The Sensor Can Be Caused By Branches Of Trees And Bushes, Curtains, A Fan, Domestic Or Wild Animals, Etc. Also, Bulbs With A Radar Sensor Sense Movement Through Walls, Doors, Glass, So Movement Behind A Door Or Wall Will Cause Automatic Activation.

Bulbs Do Not Have Sensitivity Adjustment. Bulb May Not Turn Off If: 1, In Windy Weather, The Bulb Will Shine All Night If It Is Installed On The Porch And There Are Branches Nearby; 2, There Is A Working Fan Next To The Bulb; 3, There Is A Motion Source Behind The Wall Or Door Within The Range Of The Motion Sensor; Q: Why Doesn't The Bulb Turn On Automatically?

Answer: In 99% Of Cases, The Reason Why The Bulb Does Not Light Up Is That There Is Strong Light In The Environment, Wait Until It Is Dark Or Check In A Dark Room. If You Think That The Bulb Is Not Working Correctly, Please Contact Our Support Team. Within Three Year, We Do Free Replacement.
