Bosch FL12 12V Max LED Worklight is a compact cordless jobsite light built for hands-free lighting in dark work areas. This is a worklight designed for inspection, service, repair, and general task lighting. Model Number FL12. If you already run Bosch 12V Max tools, this light makes a lot of sense because it gives you targeted light without dragging cords, balancing a flashlight, or asking someone else to hold it.

The big selling point here is how much usable light Bosch packs into a small body. The FL12 uses 10 LED lights and produces 330 lumens, which is enough output for under-sink work, attic spaces, service panels, equipment rooms, and vehicle repairs where you need to see clearly at close to mid range. Bosch also built in a dim function, so you can cut the output when you do not need full brightness and get more runtime from the same battery.

On the job, versatility matters as much as brightness, and this light is set up well for that. The head articulates through 200 degrees, so you can aim the beam where it needs to go instead of wherever the light happens to sit. Bosch also gives you two powerful magnets, a carabiner clip, a nail hook, and a quarter inch screw thread for standard tripod compatibility. That means the same light can stick to ductwork, hang from framing, clip to a bag or belt loop, or mount on a tripod for a more fixed setup.

Runtime is another reason this one stands out. Bosch states the FL12 delivers about 6 hours with a 12V 2.0 Ah battery and up to 12 hours with a 12V 4.0 Ah battery. Hold the power button for dim mode and runtime doubles. That is useful for long service calls, punch list work, overnight outage prep, or any situation where you need light through most of the day without swapping batteries constantly.

The build is straightforward and practical. Bosch lists the housing material as reinforced plastic, and the light itself weighs just 0.6 lb, so it is easy to carry and easy to position. At roughly 5.5 inches long, 2.675 inches high, and 2 inches wide, it fits where larger work lights do not. That compact size is a real advantage for HVAC techs, mechanics, plumbers, electricians, and remodelers working in cabinets, mechanical chases, crawlspaces, and other cramped spots.

From a system standpoint, this is part of the Bosch 12V Max cordless platform and uses Bosch lithium-ion 12V Max batteries. It is sold as a bare tool, so it is a better fit for users who already own Bosch 12V batteries and a charger, or for anyone building out that smaller Bosch platform for service and install work. If you want one light that can mount in several ways, run a long time, and stay compact enough to live in the truck full time, this is the kind of tool that earns its spot fast.

Who should buy it? Pros who work in low-light areas and need both hands free. It is especially well suited to automotive repair, HVAC service, electrical work, plumbing, remodeling, and general maintenance. Serious DIY users will also get a lot out of it for basement work, utility repairs, and power outages, but the real value is clearest when you are moving from task to task and need a light that sets up fast without slowing you down.
