Infinity X1 Work Light Set: A Costco Hidden Treasure for Any Toolbox

Introduction

Some workshop gear costs a fortune, and some of it quietly punches well above its price. The Infinity X1 work light set falls firmly into the second category. Sold at Costco as a three-pack for $16.79 (a regular price of about $21.79 minus an automatic $5 coupon), that works out to roughly $5.60 per light. Even by budget-tool standards, that is inexpensive for a light that also doubles as a power bank, a clip-on lamp, and a freestanding area light.

If you shop at Costco, the set is easy to find in its distinctive 10.5 x 15 inch box, with the three lights secured by a healthy share of zip ties. The same Infinity X1 set has also been spotted on Amazon for around $40, which makes the warehouse price especially appealing if you have a membership nearby.

What You Get in the Set

Each light is a self-contained unit with a USB-C input for recharging, a USB-C output for charging a phone or other device, an integrated folding stand, and a clip. The set also includes three USB-C cables, one of which has a metal housing that feels a step above the usual bundled cable.

The form factor is deliberately versatile: you can stand it on a bench, clip it to something, hang it from a bail, or stick it to a metal surface. That flexibility is the main reason this style of light is easy to keep reaching for around the garage, the campsite, or the house.

Light Modes and Run Time

The light output is where things get interesting. The main white light runs at about 6,000K and offers three brightness levels: 2,500 lumens, 1,000 lumens, and 300 lumens. At the top setting, the quoted run time is about 1.5 hours, with around 3 hours at 1,000 lumens and around 6 hours at 300 lumens. The claimed output at full brightness is about 1,056 candela, so this is an area light rather than a spotlight. It floods a space with light instead of throwing a beam a long distance.

Beyond the white modes, there are two warm light settings at roughly 3,000K: a 300 lumen warm mode with about 6 hours of run time and 900 candela, and a 50 lumen warm mode good for around 18 hours at about 100 candela. That low warm mode is what turns this from a workshop light into a camping light, a night light, or a handy bedside lamp.

Controls and Power Lock

The single button cycles through all modes, and shutting off takes a little getting used to. After roughly 30 seconds of use, pressing the button turns the light straight off. But if you have only used it briefly on any setting other than the lowest, the button cycles through everything before it shuts down, so you may need to click through all the modes to get to off.

There is also a power lock mode: hold the button for 3 seconds and the light locks into a demo-style cycle where each press simply runs through the settings without turning it off properly. Hold it again for 3 seconds and it unlocks. This is handy for storage or transport, preventing the light from switching itself on in a bag.

Mounting Options: Stand, Clip, and Magnetic Base

The folding stand is heavy-duty with solid clicking positions, and the light includes a wire bail handle that seems decent for hanging or carrying. The magnetic retention on the base is real but not super strong. Put it next to a Milwaukee light with its famously strong magnet, or a newer Klein model, and the difference is obvious.

That said, the magnet is definitely enough to hold the light onto a vehicle, which makes it useful for changing a tire, working on an engine, or lighting up an area. You can flip it over and stick it to the underside of a metal hood, provided your hood is still made of ferrous metal.

Things to Consider Before Buying

The biggest caveat is support outside the store. The light is made in China, and the brand’s website support and warranty situation is not especially prominent. Buying through Costco helps here, since the retailer’s own return window backs the purchase, though the exact duration is worth confirming locally.

The other trade-off is the off-button behavior. Once you know the rhythm, it is a minor quirk, but anyone who frequently taps lights on and off for a few seconds at a time will notice the extra clicking.

Buying Advice

At roughly $5.60 per light from Costco, the value proposition is hard to argue with, especially given the USB-C rechargeability, the ability to charge a phone from the light, and the variety of mounting options. Anyone who uses work lights regularly knows that a few spares scattered between the garage, the car, and the camping gear is never a bad thing.

If you do not live near a Costco, the same Infinity X1 set has appeared on Amazon for around $40, which is still reasonable for three multi-mode rechargeable lights with power output. For anyone building out a small collection of versatile task lights, this set is an easy recommendation at the warehouse price.

Conclusion

The Infinity X1 work light set is exactly what a hidden treasure should be: an unassuming product that delivers far more capability than its price suggests. Multiple brightness levels, warm and cool modes, a stand, a clip, a magnetic base, USB-C charging in both directions, and three lights in the box make this a genuinely useful addition to any workshop or household. If you spot it at your local Costco, it is worth picking up.
