A small and versatile flashlight for performing color-sensitive works (any activity that required perfect color rendition), given its high color reproduction index. I've tested it with the rechargeable battery it came in with, but also with the AAA batteries and also with Ni-Mh rechargeable ones as well and I got plenty of light, also worth mentioning that the Highest output mode can only be achieved when using the default battery provided by the manufacturer or a compatible one, while with AAA batteries the remaining output modes are accessible. It has a very nice spill, it basically feel with light my entire living room, but there's a well-defined spot area as well, that nicely blends into the spill. This is not a flood light, but is definitely floody enough to make a great EDC, especially that the 650 lumens can help a lot in outdoor activities nearby your home. I do recommend this flashlight due to it's small size and great output power, but also due to it's high CRI emiter.
