Excelent Flashlight! Let me start of by saying it is really REALLY bright. Everyone that has seen this light is impressed.

PROS:
- Rechargable baterry: It is really easy to get out , charge and put back in. I have charged the baterry twice since Ipurchased it , lasts and insane amount of time using from time to time. Carry it daily.

- Buttons: Tactical button on the back has a really good click, and button in front is really easy to change through the diferent brightness settings.

- Brightness: The highest mode is more than you will ever need.

- LED on the mode button. When baterry is almost out a red light indicates that you have almost ended baterry life. I noticed this funtion one time We got lost hiking. After this light turned on and I noticed it we still had maybe 30 minutes till we got to camp. Used it a bit that night and the next day drained it on stopwatch and got 15 minutes on high. So after the red light turns on you still have a minimum of 40 minutes of light. By the way, when the light turns red the light automatically reduces top brightness so it lasts.

CONS: only one.

-Would have liked a back tailswich to be able to freestand when placing on a flat surface.

SO CONCLUSION:

This is the best flashlight money can buy. have tested it in many situations and places. It has never disapointed. Stop looking around and buy this one.

This is an excellent LED light that can be used as a desk lamp or clamped on wherever you need light.  The head of the light contains 24 LED bulbs, 12 in the yellow range and 12 in the bright white range.  The banks of 12 lights can be used separately or together to give you just the color temperature that you want.

The light has a control box that is hardwired into the USB cord that sits just about a foot away from the clip / base.  This is really the only negative aspect of the light that I came across.  Depending where you want to clip the light having a large control box like that so close to the clip can be awkward.

The unit is powered via USB so you can plug it into your laptop, PC or USB charger of your choice.  The control box contains a battery that allows the light to be used even when you are away from a power source.  It is rated for 20 hours at the brightest settings and 30 hours at a dimmer setting.

I saw another review that said they could not tell the difference between the brightest setting and the least bright setting and I am guessing they had a defective unit as I counted 14 different steps between the lowest and highest brightness level.  The lowest is quite dim and the brightest more than bright enough to read by.

The clip is tight and takes a big of strength to open it, which is a good thing as it should stay put when you clamp it down on something.  The gooseneck is easy to maneuver but the lamp head stays where you put it very securely.

Overall this is a really nice light.  If they would have somehow incorporated the battery and the controls in the clip / base of the light it would have been even a bit better.  With that said still a desk lamp / clip lamp that I would recommend for the quality, amount of light and versatility it offers.  It works perfectly lighting up my mixing board.

Sample provided for review.

The control box contains a battery so you can use the light even if you don't have a USB power source.

I purchased 4 laser moving lights from different manufacturers and this one is the best by far.  Much brighter and covers a far greater width.  This has many more patterns to choose from and the blues can really be seen.  My next favorite also has RGB but not near as bright but the price was $50 less.  This light is around 3x the size of the other RGB lights I have and it does the whole 50 foot width of my house by itself from about 27 feet away.  I'm keeping the less expensive ones for shining only on the palm trees which are quite tall.  If you are only going to buy one this is it!

Very bright great light.  I like the separate switch that allows selection of the lumens option  Better than the single switch selectors

best head lamp light by far.  Battery does not last long though.  I bought 2 Li-ion 14500 750mAh batteries for it thinking they would last longer than a standard AA but the 145000 just is brighter.

Love that it has additional light on handle. Also being able to go from low beam, high beam, or strobe is great. Very lite weight. Have bought many spot lights in past, this is the best so far.

This is my second light. Nothing comes close to it. The only thing I wish is that Bayco would design a multi-mode option for a brighter main LED with the option to turn it down to 150 Lumens to get the maximum run time; but I can't complain. It does suffice. I only have this light and a NiteCore MH-27. This light is amazing!

This is the best light. It is super bright and has a nice quality feel to it. The super low setting is also perfect when you want just a low amount of light!

I do a lot of night fishing and have used many different headlamps. This headlamp is superior in every way to all others.  Brighter and longer lasting charge. Easy to recharge. Best I've found..

Excellent lights.  I've been using the incandescent versions for yeas.  The only issue with those is once the battery level drops you get lots of false triggers on the lights at night.  Once they get really low on power they turn on and off every 30 seconds.  Very annoying at 3 am and the lights just come on and off all night.  But!  These new LEDs are brighter and don't seem to ever turn on until something truly triggers it with motion.  I bought 6 and I use them everywhere including my kitchen base corner cabinets.  It's always hard to find certain items and sometimes need a flashlight.  With the Mr. Beams I just open the door and it comes on providing lots of light for 30 seconds.  Great little lights.
