Good light if it lasts for you.

I loved this light. It works great. But stopped working after maybe 15 uses and 1 charge.  The light was on and just turned off.  I tried charging again and no luck. It just died.  I liked the light but something is wrong here. Maybe my unit is defective.  Found out it was the charger.  Replaced and works great again

Using it as a security flood light outdoors and mounted at 8 feet. Brightness was fine. The bulb lasted about 3 months at 4 hours per day. Certainly that is less than 22 years. Bought another bulb to give it a second chance. So far 6 months and it is still going.

I have had this light in my garage since December of 2016.  A few months ago one half of the led lights failed, and now this week the other half died as well.  If your looking for a light thats good for less than 24 months then this is for you.

This is a fantastic little light.  It's very bright and comes in a neat package.  I love the way it comes on somewhat dim and then goes to full brightness when motion is detected.
UNFORTUNATELY, as others have reported it's unreliable.  It quit working about 2 weeks after I got it.  On the positive side, I was able to get it operating again by resetting it using a staple I straightened out in the reset hole.  Time will tell if it goes out again.  While I'm glad I was able to get it working at least temporarily, I can't see myself buy additional lights that I have to go around resetting every week or so.

Overall build of the light is great, but it completely died 6 months after. Below-average on-time for the light, only used it a couple minutes a day 2 or 3 times a week. When it worked, it was fine though

LEDs sometimes burn out after a couple of years, but a great light.  Really lightweight - not for outdoor or heavy use.

Bought 2 of these lamps in January 2015. The light is great and easy on the eyes. One of the lamps, the switch stopped working about a week ago, a little disappointing. The lamp switch is stuck in the on position, so I have to unplug the lamp to turn it off. Sometimes it takes a couple of times of plugging in to keep the light on. The other lamp is working fine, just hoping the switch last.

Gives off great light, works well on dimmer. I would have given it 5 Stars except one of the 3 I installed failed after 7 months, nowhere near the 50,000 hour expectancy. However, given the price it is still a good deal.....

Good light. Not built for heavy water use. I do might paddle boarding tours. Charging port failed a few months into use as the port is not waterproof. The light is starting to go be trouble after about 19 months so thats good. Not sure its the batteries or the light.

Easy to install and have good light. Did not last 50000 hours. Lasted 18 months. Going with a different brand and will try again.

Like this light a lot, but it only lasted about a year.  The seal protecting the electronics is not good.  It received water damage near the on-off buttons, and the operation became intermittent.  I had to trash it and go with a new light.

As spare lights you can throw in a drawer to use in a pinch they're great. I use them for walking the dog and around the house when I need a little extra light. As other reviewers have reported, the durability is questionable. Two months after buying them, one has died, but at a few bucks apiece it's still a good deal. I wouldn't use them for anything where your life would depend on it - for that kind of application get a Maglite or Surefire.

Love the light that is produced. Hate that my usual service life is ~10 months.

I always replace them in pairs...so I'm rather bugged that one just went out 4 months after being installed.

But I'll continue to buy them because I love the light!

I enjoyed the lamp while it worked. I was supposed to get the one with a battery backup, but I didn't, which didn't turn out to be that big a deal because I didn't move the lamp from it's spot on my work table. The light is okay, not as bright as I'd hoped, but decent enough for a cheap lamp. My problem is that it died in under a year, definitely not near the 50,000 hours it claims it'll last. If you need a cheap lamp, it serves that purpose, but don't expect it to last for long.

I used this light for about 4 months and then the LED lost a lot of power, even with brand new batteries.  Not a great light.  The quality and durability of the body seems to be good.

I have many inexpensive penlights/exam lights that I use for work and they never seem to last more than six months.  Either they break, or I left them on, or the batteries have died. I carry a big bag of batteries and the battery tester to ascertain if the problem is with the light or the batteries. I have used the tester around the house, too, and it seems to do the job.

I like how bright this light is, though it's still not "super" bright. I use two of them at the same time and I guess this is going to be as bright as one can hope for with something of this size. So anyone complaining about the brightness just needs to accept that if you want BRIGHT, then you need to buy a fairly large lamp.

My problem, however, is that I've had the battery's die 3 times now after probably 8-10 hours of use (combination of flashing and solid lighting). I think this is much less than advertised.

Also, I have a problem with them just suddenly turning off during a ride without pressing the button.

Lastly, these clamp just fine to any round tube. That's good if you have a round handlebar. Does not fit at all on anything on my aero bike though. Solution requires getting those round bike computer mounts and attaching those perpendicularly to my front facing aero bars. At least the quick release thing on these lights makes it easy to attach/remove and those computer mounts are relatively easy to attach/remove.
