Lighting needs vary based on the jobsite, time of day, and availability of power. As a general guide, work lights with 1200-2000 lumen are perfect for compact areas like under the sink or workbenches. We have both a plug-in and rechargeable version. For medium-sized jobs like working under the hood of the car or in the garage, 4000-7000 lumens is great. For large job sites, working at night, or construction where you need the light to spread to the walls and ceiling, 10,000 lumens or more is ideal.
