If you have a power outage it can tail stand and flood the ceiling and 350 lumen on a white ceiling is like having an end table lamp and enough to see well and even read a book! A second set of batteries will be an entire evening of light. LED Lantern with BatteryGuard - 1,000 Lumens - Black The Coleman 1,000 Lumens LED Lantern with BatteryGuard stops battery drain, so youll have power. Lumens: 75 (high), 2 (low) Runtime: 3 hours (high), 200 hours (low) Beam distance: 50 m (high), 5 m (low) IPX4 water-resistant design. Strong, lightweight aluminum construction.
Rubber-edged bezel for extra drop protection. The tail and head are rubber coated for protection and the rest of the body is aluminum. Comfort-grip design lets you securely and comfortably hold your light. Its also got a good reflector that is well centered and produces a nice beam with tight hot spot and usable flood. The LED is a nice pure white with no blue or green tint like some cheap ones I've had. This technology disengages batteries to preserve battery life. Switching off the flashlight automatically. The Coleman Battery Guard Torch features BatteryGuard technology as the name would suggest. Using 3AA batteries you get great battery life and brightness with hi (350lumen for 3 hours) and low mode (10 lumen for 200 hours). The 300-Meter LED Flashlight with BatteryGuard stops battery drain, so youll have power when you need it most.
The output on the 300m is in the sweet spot for me for run time and output. This is a great solution for simplicity which is always better for reliability. BatteryGuard system stops battery drain to preserve battery life and reduce corrosion Provides up to 25 longer battery life than traditional flashlights. Conventional flashlights experience residual drain as long as the battery is connected in the circuit, even when the light is powered off. When its off there is no contact to the batteries ensuring no drain if the flashlight is on a shelf for a long time. Brightness: up to 600 lumens beam distance: up to 12 meters-specs-/specs-catchline-The 600 Lumens LED Lantern with BatteryGuard stops. The Battery Guard technology on the Coleman 325M LED Flashlight stops battery drain, so you'll have power when you need it the most. With this system they have a mechanical switch that moves mechanically to switch the modes from off to low and then high. Taking a different approach are these Coleman battery guard models, which are much more simple using only a small resistor bank and possibly a fuse and diode for protecting the LED ( I can't see all the components as they are epoxied for protection) I did open it and take a picture of the sturdy switch and resistor design, you can check that pic out below. Coleman battery guard 200 lumens mini led lantern - black Led Lantern, Lanterns, Power. In some cases they need regulation in the circuit for lithium rechargeable batteries which are much more complicated to keep healthy and not safe if abused or defective.
I own a lot of flashlights and most of the modern ones have complicated circuit boards with micro processors and or micro chips to control modes electronically and sometimes hundreds of tiny electronic parts.
