I received my two Zebralight H50 Q5 headlamps today and couldn't wait until nightfall to take some beamshots for a review!
I will start off by saying that both lights have truely identical output. Comfirmed by both my eyes and my digital camera. So don't worry about getting a dud.
The light itself has really nice finish, smooth threads, and feels sturdy considering how lightweight it is.
It comes with the the headband and attachment, an extra attachment by itself, another attachment that is connected to a draw string (not sure what it's really for?), a clip so you can clip the light to your pocket, and a little device that is used to block out the glare from the beam. All of the attachments are the same and are all glow in the dark. Not your normal weak glow in the dark like the glow in the dark tailcaps on some current models. These things REALLY GLOW! I'm not sure for how long but wow they are bright!
The one downfall I can find so far is that the light is not all that tight when sitting in the headband attachment. It can spin around if there is too much movement. I'm sure someone on here will figure out a easy way to solve this problem, but before then I have to say it is a downfall.
On to the pics. The first pic shows the light (without headband) compared to a Fenix P2DCE. You can see that it is incredibly small! The second pic is the beam on low, followed by medium, and then high. You can see that the levels are spaced pretty far apart unlike many lights on the market. I had a hard time capturing what I saw in person. All modes are quite a bit brighter than these pictures represent. I could easily navigate my basement in the low mode (it was actually quite bright) but it looks nearly pitch dark in these pictures. So keep this in mind if you think that the pics don't make the light look very bright.
Pros:
Amazing flood beam!
High output on high, and low output on low
Great fit and finish
Super lightweight
Cons:
Light could possibly shift in the headlamp attachment while running/jogging or intense trail climbing.
OUTPUT
I just got done taking some overall output readings of my Zebralight H50 Q5 a few minutes ago, here they are:
Low = 9 1.8
Medium = 58 11.6
High = 354 70.8
With my lightbox I found a reasonable formula to get approximate lumens. Just divide my overall number by 5 and it will be very close to the amount of lumens coming out of the front of the light. I have tested this with all of my lights and I'm confident that it is very close to exact, and if anything I think it will project a slightly low number. With that said here are the lumen ratings for the different levels:
Low = 1.8 lumens
Medium = 11.6 lumens
High = 70.8
You can see that my lumen figures are very close to what the manufacturer claimed for this light. They are very slightly under their claims on the low and medium settings and slightly over on the high. Either way it does show exactly how much brighter each setting is from the one before it, and gives a rough idea as to how much light it is putting out.
Is there a light on the market (cheap hopefully) that is proven to be EXACTLY a specific lumen amount? I don't care how bright or dim it is as long as it is basically guaranteed to be an exact amount. I figure if I can find a light like this it will make it possible for me to get a near perfect formula for testing all of my lights.
