Zebra H502 Headlamp

Whether you are stocking your bug-out bag or just want a great all-around flashlight for home and trail use, you may want to check out the ZebraLight H502.  Read on for the full review of the Zebralight H502 Flood Headlamp.

First thing you will notice with the H502 (H502d, H502c, H502) is that it that the light doesn’t come out of the top of the flashlight.  The light is directed out at a 90-degree angle.  This allows you to use it as a headlamp (with the included strap), a standard flashlight, or clipped on your belt (removable steel clip included).  The fact that the light is a flood lamp style makes it perfect for trail walking or around the house.  When trail walking I like to clip it on my belt, as opposed to using it as a headlamp, this keeps bugs from flying towards the light and ultimately ending up in my mouth.  Doesn’t happen as much when the light source is attached at the belt level.  This 90-degree design is also handy around the house.  If you are working on a project and need a flashlight it is easy to set it down on end, and unlike a standard flashlight it won’t shoot the beam to the ceiling.

– All levels are current regulated.
– Battery capacity indicator (LED flashes 1-4 times. 4 short clicks to start)
– Low battery alert when the light is switched Off (LED flashes every 80 seconds if the battery voltage is below 1.06V)
– Programmable M2 and L2
– LED driver circuits sealed completely from the battery chamber
– Unibody design (improved from the H501, similar to the H51)
-Recessed switch (improved from the H51 and H501)

ZebraLight H502 L2 Flood Headlamp

The ZebraLight H502 is powered off of a single AA battery and is just barely bigger than the battery itself.  There are three levels of brightness – low, medium, and high.  You can expect the battery to last as follows:

  • Low (100 lumens) – 3.5 hours
  • Medium (160 lumens) – 2 hours
  • High (260 lumens) – 1 hour


In addition there is a strobe light feature as well.  A cool surprise feature is the ring around the light element will glow in the dark after charged by the light being lit.

If you haven’t used a flood lamp style flashlight befor you will be in for a pleasant surprise.  The light is super bright and throws a very nice wide pattern.  Works for just about anything inside or outside the house and gives you the felling that the lights are on!  All of this goodness can be yours for just $69 here.
