This is our third product evaluation of a work light for automotive shop use which can can double as emergency lighting during power failures. In several months of CAC testing, both in the garage working on Corvettes and during power failures we had last summer, the GearWrench "3000 Lumen Rechargeable Area Light" (PN 83139), proved to be a very useful piece of equipment.

It doesn't put out as much light as the 5000-lumen"Big-Ass Light bar" we tested a while back and covered elsewhere, but it weighs less and, when the lighting need requires the device to stand vertically, the GearWrench Area Light takes up less space than the Big-Ass Lightbar.
Our favorite features of this tool are: 1) it has up to 10-hours of run time, fully-charged and  operated on "low" setting. That's a heck of a lot of time working on cars. As an emergency light, you could leave it on all night during a power failure. 2) The product sends constant current to its light emitting diode (LED), ie: it doesn't dim when battery charge gets low.  3) It pivots vertically through a 120° arc so you can throw light where you need it. 4) It has a well designed base, so regardless to what angle the light is adjusted, it won't fall over. 5) It runs on its battery, or you can plug it in to 110-volts AC, light a work area and charge the battery at the same time.

The information GearWrench supplied to us with the product states its LED light source uses "COB" technology. Not knowing that that meant, we did a little digging and we learned that "COB" means "chips-on-board". It's a manufacturing process which mounts many LEDs on a single substrate chip. Multiple, tiny LEDs are connected then packaged onto a single ceramic or copper circuit board and function as a single light source. The key advantage of COB LEDs they are both small and bright.

Other features of this work light are: a lithium-ion battery and, when it reaches full-charge, a charge indicator light turns green. The light has five output levels from 600-lumens on "low" to 3000-lumens at full-power. It meets the "IP67" water resistance specification which means it can be immersed in water up to one meter deep for up to 30-min. Finally, it has a one-year, limited warranty.

What kind of jobs has this work light helped us complete? One time, late at night with a C6 partially on the driveway, we had to jack up the car and get a front tire off. I set the GearWrench Area Light on the ground, angled it up slightly, turned it on and had plenty of light with which to do that work.

Another time, we were working under the rear of a C7 and had to read some part numbers on some little tags on the suspension. Doing this required a bright light and the car wasn't very high in the air. The 3000-Lumen Area Light was the perfect solution. I slid it under the car with me, pointed it a little upwards, turned it on and could easily read the part numbers.
One night last summer, we had to deal with one of the local power company's "public safety power shutoffs" which are sometimes forced on people living in our county as a pre-emptive, anti-wildfire strategy. We used the GearWrench 3000-Lumen Rechargeable Area Light to light our entire living room. As an emergency light, it works awesome.

This product is one of a family of work lights GearWrench markets to both professional and advanced DIY service technicians. It's the biggest/brightest of a series of tools which includes the 150-Lumen Flex-Head Work Light we tested 18 months ago. Both part of an eight-member family of lighting products which include area lights, work lights, a headlamp and some flashlights. “Whatever lighting your job requires," Product Manager Paul Steinweg told the CAC, " GearWrench has a professional-grade solution with output ratings from 30 to 3,000 lumens and, all of our professional lighting products are built to last.”

That last sentence is one with which we certainly agree. The 3000-ln Area Light is built for tough duty. Its housing is a mix of aluminum and composite plastic construction and has a glass lens. The other one of the GearWrench lighting line we use has been slid across the floor, dropped on the ground and went camping in the rain. It's been used for all sorts of shop work as well as household and emergency lighting tasks.
 
All these GearWrench lighting tools are all pretty darn good stuff. For more information see the lighting section on the GearWrench web site.
