Nightstick XPP-5450G Intrinsically Safe Permissible Dual-Function Headlamp, Green 61mm

Found the unit a bit difficult to adjust on the hard hat but got it dial in eventually. Also impacted by the need to mount goggles on the helmet, that might be rare, but this was my situation working around chemicals.nice and bright. batteries last a couple of days with intermittent use approx. 3.5hrs a day.A bit of a pain to unscrew the cover on batteries but that's the nature of the beast to make sure no sparks escape.Would highly recommend the product. Most other comparable products are around double the price.BTW, the packaging looked like the driver dropped it on the road and ran over it a couple times...but it still worked.UPDATE #1: After a few months of usage, the height adjustment is starting to fail. As I walk, the light begins to droop until it's shining down in front of me. Dissappointed that the adjustment didn't last longer. I might be able to discover a way to lock it back in, but have not taken the time to examine the mechanism yet.UPDATE #2 9-2018: The adjustment problem has now reach its ultimate end. The hinge on bottom has basically disintegrated. Now, when I put batteries in and tighten the screw, the bottom hinge pops loose. The product is no longer usable. The hinge is just cheap plastic, that is a shame, I kind of expected better from nightstick. However, it still seems to be the best option vs. price available so I am planning to order it again. Hope I can get 3 years of intermittent use out of the next one. I do really like it when it is working...lite and bright.

Great quality product. It meets standards that I was looking for.

Another great headlamp bright and durable with thick rubber headband no shifting around.

Everything is fine, the flashlight works. It’s good that there are batteries included. For my work, the most necessary headlamp for its protection.

I’ve had one for several years used to get to my deer stand. One of the ears eventually wore out and broke so this year I bought another. Great light and heavy duty. This one has rubber and cloth band. Well recommended to outdoor enthusiasts so want a great head lamp

Good light, only flaws is that it didn't come in a box. It was just in a clear plastic bag. And batteries were not included.

Live product, great for walking the dog at night. Safety feature for visibility and frees up my hands.

The battery compartment does not securely seal the battery compartment when NiMH batteries are inserted. Brighter than I expected.Dec. 17 2021. Practice makes all the difference.If the battery cover is deliberately closed with the left-hand thumb & middle-finger -- the light face pressing into the palm, the screw will hold it securely against water and presumably, vapors with no risk of stripping out the threads.
