Question: Please clarify that 300-Lumen Flux is for each unit or for 3 units put together giving total of 900-Lumens.
Document: These are great but they can go in areas solar will not work. These lights are pretty bright for being battery operated! I have purchased 8 of the 140 lumens and 6 of these 300 lumen lights. My family cant believe how wonderful these lights have been for us. If they made another version of these with a higher output of lumens I would for sure buy from mr. beams. Probably the best battery operated lights on the market?
I don't know maybe it was shorted. The third unit worked just fine also. All units have a decent motion sensing capability and the brightness is good for a 400 lumens light. I am placing these around my house so i don't have to find flashlights anymore that my kids have hidden around the house. I will probably end up buying more from Mr. Beams even though the one unit had issues. Hey, It happens!
This product has a nice bright light (about 200 to 300 lumens) for battery power, but one might want to put it in a place that is not subjected to the rain. I ordered a pack of three, but one was broken. After lots of questions, the manufacturer sent me a replacement. Several months later, one of the other lights I put outside stopped working because it was full of water.
It's really bright! I bought a 3 pack after seeing this bad boy in action. I had a single LED Mr. beams 140 Lumens for 2 years. It worked perfect, I actually dropped it and it broke. It was outside for 2 years by my garage and saw those crappy Nj snow-storms and took the beating. I upgraded to the 300 Lumens, I will keep you posted on how she does.
I originally purchased the Mr. Beams MB363 (140 lumen) 3-pak, but exchanged them for the MB393 (300 lumen) which I'm happier with.I had a good idea of what expect out of 140 lumen as that's the output of my only LED flashlight that's worth having. The lights cast a decent spot and I was even surprised by the shadow.
I now have 5 of the Mr. Beams lights in areas that need additional light, all of them mounted under overhangs on garages and porches, so they are not fully exposed to the weather. The first 2 are the 150 lumen models, and I added the 300 lumen 3-pack recently. They are just great. Batteries last a long time, even in cold climates, and the lights come on when appropriate in terms of motion and darkness.
Just ordered 3 units for my backyard last month and each lamp casts sufficient light for a battery operated unit. The timing is good but the sensitivity could be a touch better. 1 month in- So far so good. Contemplating ordering 3 more for front of the house.
With the Dorcy units anytime one was within the 20' to 30' of the door the unit lit and stayed on as long as any one of them was moving. This meant the light stayed on and i could watch them as they milled around. With the MB390 it would be hit or miss and detect 1 of the 3 then go out as all 3 were in  blind spots. Often times they would literally sneak up on the door and I would not see them until the last 4' or 5'.
Ordered 3 units, but one was defective and Amazon replaced it. The defective unit would go on without detecting motion and would not turn off. The sensor sensitivity seems to vary from unit to unit, but the sensor range is about 15-20 feet. When triggered the light will shine for 20 seconds without additional motion, but will shine continuously as long as motion is detected. So far I am satisfied with this light.
I ordered the 3-pack. I use D rechargable batteries. The units seem to be well made and waterproof, thanks to the o-ring gasket. The light is quite bright. The 2 complaints I have is that the sensor doesn't actuate the light until I'm about 12 to 15 feet from the unit in any direction, 25 feet is what is claimed ! I have 2 units one on front and one rear door of my house that are acceptable.
Answer: yes
