A Lumen specification is the measurement of the overall light output. A Lumen rating is the average brightness
and intensity in all directions. Generally, Lumens are referred to as the total amount of light emitted from the
LED as measured in an integrating sphere.
STKR® with Lumen Tech LEDs rates each product's overall light output, or brightness, in Lumens.
Not all Light Emitting Diodes (LEDs) are created equal. At STKR® we use Lumen Tech LEDs in all our products.
Lumen Tech™s daylight white LEDs combine the most intense light output in combination with a wide viewing angle.
This provides STKR products with a crisp bright white light that illuminates a large surface area making STKR
the most versatile task lights.
Lumen Tech LEDs for STKR products have been developed to deliver the best technical performance.
STKR products have been designed and engineered to deliver to our professional customers innovation,
technology, and the best functionality.
Competitors tend to win over their customers with sheer amount of low-grade LEDs in their products. More LEDs
are not better when inferior LEDs are being used. Did you know that more LEDs use more power and drain batteries
Inferior LEDs often claim big millicandella (typically listed as MCD) specification numbers, but MCDs
specifications are only half the story. The true total brightness of a task light takes into account the viewing
angle of the LED. Inferior LEDs produce a very focused small light dot on the work surface or area, even when
using over 20 LEDs. This is not the type of LED that should be used in a task light, that is why Striker only
uses Lumen Tech LEDs.
High-quality Lumen Tech LEDs are a combination of light intensity and a wide viewing angle.

It may not be getting enough charge. Make sure unit is installed where it can get maximum sun exposure for 8
It may be switched to the OFF position. Move the switch to the "ON" position.
The unit could be located near a strong light source. Make sure unit is installed away from any strong light
sources, such as an existing outdoor light. Sunlight sensor is built into the solar panel, avoid strong light
hitting solar panel.
Unit not efficient under trees. Move the unit to another open location.
The Solar panel could be dirty, or covered up. Wipe the solar panel clean and make sure it is always free of
The Mobile Task Light will operate on high blinding you with 1200 lumens of light for approx. 1.25 hrs.
If you need longer run times mellow the Mobile Task Light out with the Low mode. Don't let the word "Low"
deceive you. The Mobile Task Light is never truly mellow. Low still burns retinas with 300 lumens for approx.
Run times are dependent on the outside ambient temperature (yep, temps affect LEDs).
The Mobile Task Light is designed to run at full brightness until the Lithium battery falls below operating
levels. This ensures you get full brightness the entire time it is running, unlike entry-level flashlights
that only operate at full brightness for a few minutes, then slowly dim to nothing.
Put on your sunglasses when you turn The Mobile Task Light on HIGH as it will be tossing 1200 lumens into
your eye holes! For those of you who aren't impressed by the word lumens and twelve hundreds of them, just go
stare at the sun...it’s kind of like that (please don't really do that). Low is a romantic 300 lumens. Get
ready to Netflix and chill... Wait no! 300 lumens is still crazy bright. Most flashlights are well below that.
We designed The Mobile Task Light Low setting to produce 300 lumens. Are we crazy...or are we bright? It is up
to you to decide. Please be kind :)
The Mobile Task Light will take approx. 4 hrs. to charge from 0% battery to 100% battery with a 2 amp USB
charger. 2 amps is the max we recommend feeding the Mobile Task Light. A charger block, computer, laptop, car
charger, etc. with less amps will work fine but take a little longer.
Give the Mobile Task Light a tail by plugging in that USB cable and feed him/her (you determine your Mobile
Task Light's sex when you get it). If you need longer run times, just plug the Mobile Task Light into a USB
charger. Performance, when plugged in, varies due to the different amp outputs of different chargers. 2-amp
chargers are the max you should feed the Mobile Task Light.
The Mobile Task Light loves long walks on the beach, even if it is raining...just don't take it swimming. It
never was much for the doggy paddle, plus it will die a sad drowning death. The Mobile Task Light has a
waterproof rating of IP65, which means it is water resistant, but not totally waterproof. If using in wet
conditions, just be sure to keep the USB charging plug well sealed, and whatever you do, DON'T plug it in (or
use it plugged in) while wet or raining. The brightness of the Mobile Task Light is shocking, but that is the
only part we want to be doing the shocking.
The Mobile Task Light is powered by hard-wired dual-lithium batteries. Although Lithium batteries are
wonderful and last a long time, all lithium batteries get tired of charging and discharging eventually. For
those who nerd out on batteries, there are 2 2000 mAh 18650 hard-wired in parallel. If that means anything to
you then yes, when the batteries start to get tired of charging and discharging, then you can perform open
heart surgery on your Mobile Task Light and solder in some fresh 18650s (don't exceed 2000mAh). For those of
you who aren't so impressed by battery talk, you shouldn't need to worry about this. Just be sure and charge
or discharge (use the light) your Mobile Task Light at least every 6 months to prolong the life of your
The switch on the Light Mine can stick when first being used, so I would first like to make sure that you
have it completely pushed over to the “ON” side.
Sometimes the switch needs to be pushed over hard, using the butt of your thumb. The switch can click once but
needs to click over a little farther to stay on.
While it is possible to change the batteries in the Magnetic Light Mine, please be very careful. Replacing
the batteries does run the possibility of damaging the whole unit. Although, if done with care, there should
not be an issue.
Pressing on the locking tabs with a flat-head screwdriver will open the body. Pressing too hard will
snap/break the locking tab and/or tab receiver, this is the difficult part so be very careful.
The batteries are LR44 alkaline. Silver oxide equivalents (SR44) can be used but do not mix alkaline
batteries with silver oxide batteries. (Silver Oxide batteries will last longer but the initial brightness of
the LED will be less) When removing the batteries, you will notice they are shrink-wrapped. Your replacement
batteries will need to be isolated as well. Clear packaging or electrical tape works well, just leave the
ends exposed for the electrical contacts. (Please dispose of batteries properly)
Make sure the lock rings are tightened down all the way.
Inside the switch is a small aluminum lock ring with two small holes used for tightening the lock ring. If
this ring is not tightened down completely the switch may not work consistently or even at all. We suggest
using a ballpoint pen, a paper clip, or other small pointed utensil to tighten this ring, twisting the ring
clockwise until it is tightened and no longer moves. This should correct the issue and allow the switch to
Be sure there are no obstructions to either side of the bottom sensor on your unit. The sonic pulses come out
in a cone shape and could be catching a surrounding object to focus on instead of the vehicle.
The main difference is the distance that is measured. The white Sensor measure 1 foot to 4 feet. While the
Grey Sensor measures 6 inches to 6 feet. The Grey Sensor is also equipped with a walkway light. When
purchasing, it will be based on the distance needed for your garage and/or aesthetic.
