Nitecore Thumb

Point and Click

The ideal worklight is one you don't have to hold. Nitecore's Thumb allows you to go hands-free and still have your light fall exactly where you need it. Clip it to your pocket, bag strap, or hat brim, and tilt the head to the perfect angle. Illuminate your hiking path, work area, or car engine. 120° of flexibility allow you to aim the 85 lumen beam wherever you want it. Adjust your output with three different light levels. Both the red and white LEDs also feature a flashing mode in case you need an ID beacon. Recharge the thumb with any USB micro cable (the same connector used for most smartphones). The embedded charge indicator is red while charging, and turns green when your battery is full again.

Unique Red Light

Never used a red light before? You won't believe the difference. Red light is gentler on our eyes than white, making it great for situations where you want to preserve your night vision. Night photography, astronomy, wildlife observation & tracking, stealth operations, and emergency response are all circumstances where red light excels. The red light is located on the body of the Thumb.

Shakes Off Rain and Dirt

The Thumb's mighty body is made from polycarbonate, the same material used for riot shields and motorcycle helmets. Its parts fit together precisely, protecting it against rain and dust, and earning it a protection rating of IP65. Its dual switch design allows you to independently control the red and white lights. And the integrated keyring connector is able to withstand incredible weights. Wrap your hand around the Thumb!

Nitecore Thumb USB Rechargeable LED Worklight with Tilting Design - 85 Lumens -
I found this light to be so great my own mother wanted one, so I ordered one for her. This product is true to its advertising and features. I have found it to be useful while trimming my horses feet (being bent over and not having to worry about my light falling off my head as with most head lights with elastic bands) to carrying groceries in after dark. Who wants to slip on ice, trip on a pet, or struggle finding the key whole on your door nob because you forgot to turn on the porch light again.

I could see this light as a great safety light while riding horse or bicycle... to reading by low 2 lumens when camping, just don't fall asleep and run that battery down during the night. I have found that the 85 lumens setting is true to a 4 hour run time. The clip is very secure on the bill of any hat I've tried and I don't see it accidentally falling off.
  • Great light that offered several setting for hands free tasks.
  • nit-picky:
  • Would love to see this light improved to allow a slightly larger range of tilt. Currently only tilts one way (and doesn't like to "close" once used, angled about 5 degrees) having the option to wear this on your hat and have the tilt go both ways, even a 10 degree range would make this light perfect.

Nitecore does it again

Solid thin light, perfect for pocket or on a keychain. 120 degree foldable head is nice for use in vest pocket. 85 lumens is decent for its size. Sturdy clip for hat or pocket makes this more versatile than what I originally thought it would be.

Nightcore Thumb USB Rechargeable LED worklight w/Tilting Design

This light is an awesome keychaing light. Buttons are flat and are not easily activated accidently. The UV light is great for reading IDs and other items that react to UV light. I has a belt clip and keyring clip. Awesome light for the money.

Good durable light

Have had this light on my work key chain for the past 5 years. Been used and abused and still works great and hasn't broken. Can put it on a ball cap. Be awesome if it was 200 lumens but the 85 has been sufficent. Great light and highly recommended.

Best Nitecore keychain light I've had so far
March 17, 2020
I've had several Nitecore keychain lights, some of them more expensive than this model. The least expensive of the bunch (the "Tube") has been good, though its activation button tends to wear out after about a year of constant use. This one, with its two-button enable/disable approach has been the best so far and IMO gives more quality for the money than the pricier models. I wish it would default to low intensity when it's first switched on, but that's a minor nit-pick.
