A:
Solution 1: Turn off the flashlight and unscrew the light body a few turns or take out the batteries.

Q: Why does the TK35R downshift to a lower mode after being used for a while and the higher mode cannot be selected?

A: There are two reasons:
1. Intelligent Overheat Protection
The flashlight will accumulate a lot of heat when used at high output levels for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature.

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until the lowest output is reached.

A: The reasons that may cause the light to flicker, shine intermittently or even fail to illuminate:
1. Poor battery level.
Solution: Recharge or replace the batteries.

2. The contact or contact point of the batteries or flashlight is dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact your authorized distributor.

A: It is recommended to use two Fenix ARB-L18-4000 batteries. Batteries from the Fenix ARB-L18 series are also recommended. Other Li-ion batteries are not recommended. As unmatched batteries may cause the flashlight to fail to work normally.

Great Product

"This is a great light for pest control. I can light up dark dormer returns on tall 3 story houses to identify bat entry points in full daylight. The black light can illuminate rodent urine and fresh rub marks over 10 ft away. Just like all of the Fenix products I have purchased, I am always extremely impressed."

TK35R is Very High Quality

"Very happy with the TK35R. The brightness and option for UV is just what I needed. The only issue is that it is a bit hatd to hold and press the selector with one hand using my thumb, mostly due to an old hand injury that causes joint pain. But I can live with that due to how great this flashlight is."

Jack Of All

"This Single Light Can Handle ANY SITUATION That You May Encounter. From Checking Your Hotel Room For Clean Bedding With UV Light To Search And Rescue To Self Defense. No Batteries To Stress Over. Built Like A U. S. Battle Tank. Highly Recommended"

James B. (5/5)

Do NOT buy products from Fenix Store!

"This is my first bad review. The seller has always responded if I had a problem and worked out any issues. Fenix Store does not respond to my defective flashlight issues; Fenix Store is NOT owned by the company that manufactures the flashlight. Fenix Store should not be allowed to disguise themselves as Fenix when they are just a third party seller with horrendous customer service. The UV on my flashlight does not work. It lasts for less than a minute then goes off. Customer service at Fenix Store has not responded after many attempts to contact them. My calls go to voicemail and are never returned. Again, do not buy anything from Fenix Store."

TK35R High Performance Flashlight. 🔦

"Excellent! Light and easy to use. Gets a little warm when operated too long on the high beam."

Steven O. (5/5)

Nice light

"It took about 10 minutes to figure out what and switches buttons to use, but once that was done it's been a great light to use and almost unbelievably bright"

Thomas C. (5/5)

Love this!

"I've always loved Fenix lights and this is another great one! I collect flashlights and Fenix is definitely one of my tops. This light is gorgeous and bright. Bravo"

Jeremy S. (5/5)

Fenix Quality

"Nice light and beam pattern. Like that it is flat where you hold it. Copper accent looks great!"

MATT D. (5/5)

Nice new version of a great light

"This is a nice new version of a great light. I have a few different ones, including the previous version and think it's one of the best flashlights I own. Unfortunately I think the price point is too high. Adding the UV option to this new version is great! I might pick this up if there is a 30% promo."
