The light ranger 4 000 puts out a ton of light. It's the perfect light for contractors. Anybody who works in dark spaces people like plumbers or HVAC people who like to work out in their garages and just need some extra light and it's great because you can stick it pretty much anywhere when you take it off of its mounting pool. The battery lasts a really long time and because you can cut the light down to 2,000 lumens when you don't need it at full brightness. You still get a ton of light even at half brightness. It's highly adjustable and comes in a fantastic case to keep everything safe. This would be an excellent light for police firefighters any EMS responder who would need light somewhere immediately when they arrive on a scene. Anyway, this is just another great light in this light ranger lineup. Pick one up you won't be disappointed.
