MBI HF-R™ Ti UTT (ultimate trit tail) - The worlds most powerful 2inch flashlight.

All new 5mode version

Sporting the same internals and power as the original MBI HF™, the HF-R Ti UTT is a sleeker titanium version designed with a minimalistic profile.

Ranked by everydaycommentary.com as the #1 keychain flashlight in the world, once you become accustomed to the power and versatility combined within the tiny package that is the HF-R, you may too find yourself needing to carry far fewer flashlights as this one will simply blow away lights that are far larger in size.

There is nothing else as powerful in this size/class.

This latest batch is the brightest ever!

The MBI HF-R™ unique rotary switching mechanism allows you to switch modes instantly and directly to the mode of your choice without ever having to worry about losing the tail or head as with a typical twist-switch flashlight.

The new UI (user interface) is like a clock with 6 positions as follows:
OFF - M1(low) - M2 - M3 - M4 - M5(high)
You can rotate the tail either left or right to get directly to LOW or HIGH from the OFF position.
The tail can freely rotate 360 degrees, independently of the body so there is no unnecessary wearing of the threads and no parts to accidentally come loose.


Light, yet rugged the MBI HF-R™ was designed and refined with the help and feedback of some of the most knowledgeable flashlight experts on the planet right on candlepowerforums.com.

Important Note about shipping time: I expect I'll be overwhelmed with orders for the HF-Rs as soon as they go in-stock. Even though everything in-stock has passed inspection and is ready to go, I may need up to a week to put together your specific choice, get it packed and to the post office though I'll try and get it out as soon as possible. Please do feel welcome to contact me directly before ordering if you have any urgent timing needs.

In case you don't see the specific tail type you want in stock, please add a note to your order or feel free to contact me and I should be able to swap it for you. 

Warning: NEVER look into the LED directly or you may be seeing ghost images of the sun for hours afterwards.
