The Olight Seeker 4 Pro measures just 5 1/2″ long and 1 3/8″ wide at the bezel but packs a lot of illumination into that small package.

Olight’s website advertises a maximum output of 4,600 lumens with a 260-meter throw.  In my testing, 260 meters may be a little optimistic,  this isn’t a dedicated-long-range light and it doesn’t have any narrow focus.  What it does very well is illuminate large areas.  At full power it easily turns a half-acre of my property into daylight.   The trees in the center of this image are right at 100 yards distance.  The illumination drops off at about 150 yards – but different terrain may have different results.


The on/off button is surrounded by a rotating thumb-wheel to select brightness.  LED Battery charge level indicators are on the right side of the button,  light power setting indicator is on the left side of the button.

The Seeker 4 pro charges in its holster with a USB-C cable,  a direct-connect magnetic charger that attaches to the base is also available. It uses a 3.6v, 5000 mAh 21700 high-capacity Lithium-ion rechargeable battery. The Seeker 4 pro is available in 2 color temperatures.  The NW is 4000 to 5000 Kelvin and the CW in 5700-7000 Kelvins.

This light would be very useful for lighting up large areas such as warehouses and open fields.  If you are one of those folks who has to go into those deep-dark places where light just seems to be absorbed; this light brings all the lumens.  At full power it does start to get warm and it eats battery power quickly.  Being able to use lower settings for navigation is a nice touch.
