Not very bright, but you can upgrade it! – PIR Motion Activated White LED Night Light (4*AA) Reviews

posted by viamer on 05/05/2011 Certified Owner

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
Motion detection works perfectly. Real passive pyroelectric infrared detector inside! Low power consumption. Will not switch on when it is light, there is additional light sensor.
Cons:
20 mA LED is not enough for my purposes.
I heard that PIR detectors loose their sensitivity after several years.
Other:
I removed original LED and installed... Cree XMLAWT T6 (SKU 51989) instead! I had to use huge heatsink, 2.4A regulator (SKU 20330) and additional 2805 8A switching MOSFET (desoldered from SKU 26112).
Now it sinks more than 1,5 A from 4 batteries and lights bright as hell.
Bottomline:
Don't know how long it will work with 4 AA alkaline batteries after my upgrade. Its a pity that i can't install 18650 Li-Ion batteries in this small box!
