Bosch GLI 18V-1200 S
Bright 1200 lumen output with a wide beam angle and long run-time on a single 18V battery.
Who is the Bosch Inspection Light for?
The Bosch inspection light range is designed for tradespeople who need reliable, bright illumination in dark spaces like crawl spaces, attics, and under sinks. The cordless models are ideal for those already invested in the Bosch 18V Professional or 12V Max systems. The corded PLI 10,8 LI suits homeowners who want a compact, always-ready light without battery concerns.
Performance and Build Quality
Bosch inspection lights are known for their robust build. The GLI 18V-1200 S features a durable housing with a rubber overmold for impact resistance. Its 1200 lumen output is sufficient for most job site tasks, and the wide 120-degree beam covers a large area without harsh shadows. Owner reviews on retailer sites consistently praise the light's brightness and even distribution.
The PLI 10,8 LI, while less powerful at 300 lumens, offers a focused beam ideal for close-up work. Its compact size and integrated hook make it very practical for hanging in tight spaces. Build quality is good for its price point, though it lacks the ruggedness of the larger 18V model.
Battery and Ecosystem
The GLI 18V-1200 S uses Bosch's 18V Professional battery platform, shared with drills, saws, and grinders. This is a major advantage for existing Bosch users. Run-time is excellent; with a 4.0Ah battery, you can expect over 4 hours of continuous light on the lower setting. The PLI 10,8 LI uses a built-in 10.8V lithium-ion battery that charges via micro-USB, offering about 2 hours of use per charge.
Alternatives to Consider
If you are not invested in the Bosch ecosystem, consider the DeWalt DCL050 or Milwaukee 2360-20. The DeWalt offers similar brightness with a magnetic base, while the Milwaukee has a longer run-time and a pivoting head. For budget buyers, the Ryobi P721 is a strong cordless option.

Bosch GLI 18V-1200 S
Best OverallPros
- Very bright 1200 lumen output
- Wide beam covers large areas
- Long run-time with 18V batteries
Cons
- Heavy with battery attached
- No built-in magnetic base
The GLI 18V-1200 S is the flagship inspection light from Bosch. It delivers a powerful 1200 lumens with a wide 120-degree beam, making it ideal for lighting up entire rooms or large crawl spaces. The light has two brightness settings and a strobe function for emergency use.
Owner reviews highlight its robust build and consistent performance. The main drawback is its weight, especially with a larger 5.0Ah battery. It also lacks a magnetic base, which some competitors offer. However, for pure brightness and coverage, it is the best Bosch option.
Bosch PLI 10,8 LI
Best BudgetPros
- Very compact and lightweight
- Integrated hook for hanging
- No battery platform needed
Cons
- Lower brightness than 18V models
- Limited run-time (2 hours)
The PLI 10,8 LI is a compact, corded inspection light that runs on a built-in 10.8V battery. It is perfect for quick jobs in tight spaces like under sinks or inside electrical panels. The light has a focused beam and a handy hook for hanging.
Owner reviews appreciate its small size and convenience. The main limitation is the 300 lumen output, which is fine for close work but not for lighting up a room. The built-in battery also means you cannot swap batteries on the go.
Bosch GLI 18V-600
Best Compact 18VPros
- Compact and lightweight for 18V
- Good 600 lumen output
- Integrated hook and magnet
Cons
- Not as bright as the 1200 model
- Beam is slightly narrower
The GLI 18V-600 is a more portable version of the larger 1200 model. It offers 600 lumens with a 100-degree beam, which is still very usable for most tasks. It includes a hook and a magnetic base for versatile mounting.
Owner reviews like its balance of brightness and size. It is a great middle-ground option for those who need cordless power but want something easier to carry around. The magnetic base is a useful addition for metal surfaces.
Bosch PLI 18V-1000
Best High Power CordedPros
- Bright 1000 lumen output
- Wide beam coverage
- Good run-time with 18V batteries
Cons
- Similar weight to the 1200 model
- No magnetic base
The PLI 18V-1000 is a powerful cordless light that sits between the 600 and 1200 models. It offers 1000 lumens with a 110-degree beam, making it a strong performer for most job site needs. It uses the same 18V Professional batteries as the other models.
Owner reviews note its good brightness and run-time. It is a solid choice for those who want high output without the top price of the 1200 model. The lack of a magnet is a minor downside compared to some competitors.
Bosch GLI 18V-300
Best Ultra-CompactPros
- Extremely compact and lightweight
- Uses standard 18V batteries
- Good for close-up work
Cons
- Lowest brightness in the range
- Narrow beam angle
The GLI 18V-300 is the smallest and lightest 18V inspection light from Bosch. It is designed for focused, close-up tasks like inspecting wiring or reading labels. It uses the same 18V Professional batteries as larger models, so it is a convenient addition to an existing kit.
Owner reviews appreciate its portability. The 300 lumen output and narrow 80-degree beam limit its use for general area lighting. It is best used as a secondary light for detailed work.
What to Check Before Buying an Inspection Light
Brightness is measured in lumens. For general work, 600-1000 lumens is sufficient. For large areas, 1200 lumens or more is better. Beam angle determines coverage; wider angles (100-120 degrees) are better for area lighting, while narrower angles (80-90 degrees) are for focused tasks.
Battery compatibility is crucial if you already own power tools. Stick with the same battery platform to save money. Consider weight and mounting options like hooks or magnets for hands-free use.
Mistakes to Avoid
Do not buy a light with too low a lumen count for your intended use. A 300 lumen light is fine for close work but will not light up a room. Also, avoid buying a cordless light without checking battery compatibility with your existing tools.
Do not overlook build quality. A cheap light may break easily on a job site. Look for rubber overmolds and impact-resistant housings. Finally, consider run-time; a light with a small battery may run out quickly during long tasks.
