5 of 5 A lower lumen light with extras September 17, 2023
Reviewer: Cliford. S from Fairbanks, AK United States  
The Nitecore CU6 seems to be the perfect combination of multi-colored lights, hence the “Cameleon”. The not too bright features are a blessing in low light situations where too much light is a dead give away. I like the option of being able to change the hue when needed on the light it’s-self without having to fumble with filters. Everything is literally at my finger tip.

5 of 5 Awesome service and awesome light! August 28, 2023
Reviewer: Paul from Delta , BC Canada  
Had to get a replacement CU6 for my brother in Africa after he dropped the one I gave him a few years ago. Fabulous service from Nitecore with fast Shipping to Canada. And if you’re interested, it’s a great and very versatile light. Especially if you’re going to be out in the wilds. The white light is great for around the camp. The red and green great for animals and preserving night vision. And the UV is the best out there. Perfect for scorpion hunting without having to get right up close. They just pop out of the darkness! Awesome!!

5 of 5 It’s gonna be the death of me... March 11, 2021
Reviewer: Cody from Northampton, Pennsylvania, PA United States  
I have 6 wonderful cats. My one cat older and starting to pee outside of the litter box. I initially purchased the CU6 in order to find cat urine. Shipment and delivery was fast and painless. Products were neatly organized in the box. Popped the battery on the charger and waited for it to charge. 3 glasses of wine and an hour later the battery was charged up. My boyfriend and I were ready to enter a magical fun world where all the neon colors lit up magnificent colors. We popped the battery in, turned it on, and switched to UV mode. What the CU6 revealed to us was in fact not a fun, magical world, it was a scene from the darkest nightmares. Spots and splatters lit up the floors and walls with the force of 1000 suns. I now spend every night going around my house in the dark at all hours of the night drinking wine while shining the CU6 around in order to find, clean, and sanitize any dirty spots on our walls that I can find and it is going to be the death of me.....
