I find the FreLux an excellent “daytime” flashlight. The two batteries and boost driver allow it to run brightly and efficiently for a long time. The LH351D 5000K emitters is PERFECT for during daytime (I.e inside the office, under the hood of a car) etc.
Even in a darkened environment like backstage at a theatre, I love it. However, after the Sun goes down, and you crave something warmer, the beam can be a bit cool and a touch on the green side. But not evenly so! Don’t take any of that to mean this isn’t an amazing light. It really is. The machining is impeccable, and the multi chemistry driver is ingenious.
