I use a ZL302(?)FW when flying in the cockpit, but outside of about 5-6 feet, it is nearly useless. My Tiara C1W is a much better all around headlamp because it is not a flood type beam, but it's hotspot reflects off my screens and instruments a bit too much and doesn't have enough flood when inside of the plane. If you are doing a lot of close in work, or inside of building stuff, the 120 degree flood beam would work well. Outside, or in bad weather, you would almost be better off without any headlamp. I carry a 18650 powered handheld on a lanyard around my neck, and the ZL flood headlamp around my neck so I dictate which light to use and when to use it. Different hammers for different nails.
For reading, the 302 warm flood would be an amazing light because there is no hot spot, a very very nice even light distribution, and very wide beam. It also has as many different settings as you could hope for for just about any lighting condition you would need too.
ETA:
Here is a good representation of my 302 warm flood lamp. You can see the reflective sign in the background getting some light reflected off of it and shining back, and the picture is darker than it actually was, but not by much. It was "lighter" in the way that losing 2 pounds in still a good thing, but when you weigh 250 pounds, it is a drop in the bucket. The bucket is about 5 feet from me when this picture was taken, the wall with the sign is about 40-50 feet or so.

ETAA: The light was on the highest setting, 446 lumens. Very low cd as seen in the photo. I don't have my armytek on me at the moment to show the different however.
Here is a pic of the lamp about 18" from a beige wall. Super floody and works great for my intended purpose, but not much beyond about 10 feet, most of the time, arms length.
