Pro Tool Reviews tested Sonic Tools USA’s $55 LED Pen Light and found its side light, magnetic attachment and color-rendering useful for close-up work. The reviewer praised its versatility and 2-ounce aluminum body but flagged limited runtime, no memory for the previous setting and a two-hour recharge.
Pro Tool Reviews has tested Sonic Tools USA’s LED Pen Light, a rechargeable work light listed at $55, and concluded that its side light and magnet make it more useful than a basic pen light for close-up inspections. The reviewer praised its light weight and color visibility, while cautioning that its runtime is limited and the light does not remember its previous setting.
The light has three modes: a 100-lumen tip light, plus a side light with 100-lumen low and 220-lumen high settings. According to the product specifications in the review, runtime is 2.5 hours with the tip and side light on low, or 1.5 hours with the side light on high. Recharging takes about two hours using its integrated lithium battery.
The reviewer measured the aluminum-bodied light at 2 ounces and noted that its 6.4-inch elliptical shape helps keep it from rolling when set down. A long pocket clip and a magnet allow it to be attached to clothing or ferrous surfaces, leaving both hands free. The listed ingress rating is IP44.
In practical tests, the reviewer used it to inspect a boat compartment, a truck engine bay, an electrical panel and a washing machine’s wiring. The side light produces a broad view of nearby work, the report says, while its slightly cool color makes some colors easier for the reviewer to distinguish. The test also found drawbacks: no grip overmold or knurling, no beam-focus adjustment and no setting memory, so users must cycle through modes after switching it on.
A Side Light Adds Hands-Free Utility
The design addresses a common limitation of pen lights: a narrow light source can illuminate a specific spot but may not show enough of the surrounding work area. Sonic’s side-facing light and magnetic attachment give users another way to light a confined space while keeping both hands available for inspection or repair. The clip offers an alternative when a magnetic surface is not nearby.
That versatility may matter to mechanics and other tradespeople who need a compact light for intermittent close-up work. The review found uses beyond automotive tasks, including checking wiring and looking for corrosion. But the runtime figures make the light less suited to long periods of continuous illumination. Buyers who need hours of hands-free light may prefer a larger work light with a bigger or replaceable battery, as the reviewer advises.
The price question is consequently about more than brightness. At $55, the light’s value depends on whether its small size and multiple mounting options are useful enough to justify a specialty tool, rather than serving as a replacement for a longer-running work light.

How the Pen Light Is Equipped
The review began after Sonic Tools USA staff spoke enthusiastically about the light while discussing screwdrivers. Pro Tool Reviews’ writer said that prompted a hands-on test to determine whether the product offered meaningful advantages over a standard pen light. The report presents the findings as the reviewer’s experience, not as a controlled comparison with every competing model.
The product combines a conventional light at the tip with a second light on its side. Its stated outputs are 100 lumens for the tip and side-light low mode, and 220 lumens for side-light high mode. The report lists an integrated lithium battery, a two-hour charging time and an IP44 ingress rating. Sonic Tools USA is identified in the review as the seller, with a listed price of $55.
The reviewer also noted that the light’s beam is not optically uniform: the spill around the center shifts in color, and the LED chips’ shapes can be seen. The report treats these points as minor shortcomings for a close-range pen light, rather than evidence that it cannot perform its intended tasks.
“Sonic nails the basics while adding genuinely meaningful upgrades.”
— Pro Tool Reviews reviewer
Limits of the Available Testing
The source report does not provide independent battery measurements, charging tests across repeated cycles or a comparison against named competing lights. Runtime and output figures are listed as product specifications; the article does not say whether the reviewer independently verified them. The review also does not establish how the light holds up over long-term use or under conditions beyond its stated IP44 rating.
The assessment of color visibility is based on the reviewer’s own experience. The report does not include standardized color-rendering measurements or tests by users with different visual needs. It also does not document a formal test of resistance to drops or other forms of impact.
The review describes a lack of memory for the last-used setting, but does not explain whether a later product revision or different unit might behave differently. The $55 figure is the price cited in the report; the source does not establish whether that price, availability or any sales terms have changed since publication.
Check Price and Runtime Needs
Readers considering the light can compare its listed $55 price and stated runtimes with the demands of their work. For short inspections where a compact light, side illumination and magnetic mounting are useful, the reviewer’s tests point to a practical option. For prolonged work, the report suggests considering a magnetic light with a larger or replaceable battery.
The source says the light can be ordered directly from Sonic Tools USA. It does not announce a follow-up test, new product version or additional company statement, so further developments are not specified.

How bright is the light?
The listed output is 100 lumens from the tip light and from the side light’s low setting. The side light’s high setting is listed at 220 lumens.
How long does the battery last?
The product specifications cited in the review give a runtime of 2.5 hours with the tip and side light on low, or 1.5 hours with the side light on high. Charging is listed at about two hours.
What are the review’s main drawbacks?
The reviewer noted that the light does not remember its previous setting, lacks knurling or an overmold for grip, and offers no beam focus. The report also flags limited runtime for extended use.
Who may find it most useful?
The reviewer recommends it for tradespeople who use pen lights for short, close-up inspections, including mechanics. Its side light, clip and magnet can help illuminate a work area hands-free, but the review says users needing several hours of continuous light may want a larger-battery alternative.
