PerfectReview by Mathew
This long distance search light is perfect for security, now i can spot intruders from nearly 800 metres away before they get the chance to even jump the fence and break into the school.

Battery life is reasonable although i wished their high setting was a tad brighter., turbo mode is good for just showing off (Posted on 14/10/2016)
