The 100:1 Phase Adjuster Coupling is a multi-function component with unique capabilities. As a coupling it makes it easy to adjust the phase relationship between two shafts. As a component mount, it makes it easy to adjust the phase relationship between shaft and a mounted component.

Phase adjustment is accomplished when the drive system is stopped. Adjustments are made by hand in either direction by adjusting the knurled outer ring producing infinitely variable relative rotation of the hubs through a 100:1 reduction ratio.

Good light. Minor flaws.
Style: 180 Lumens
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.

Puts out a lot of light!
Style: 220 Lumens
I had to have an explosion proof light, and this one puts out an amazing amount of light! On flood light ( second push of button) it lights up an amazing amount of area around you. The spotlight will hit a tree in my back yard while standing in the front yard. Very impressive!

Very useful if you don't want to explode!
Style: 90 Lumens
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.
