## Description

Built for specialized after-dark visibility, the ULTRAFIRE H-B3 uses three 470nm blue LEDs to deliver a blue beam for night fishing, hunting, and outdoor field use. The beam reaches up to 256 yards and offers 100° wide-angle coverage for distant and broad-area viewing. A single-mode tailcap switch gives straightforward on/off control, while the matte anodized aircraft-grade aluminum body is made for regular outdoor handling. IPX65 water resistance supports use in heavy rain; do not immerse in water. Battery not included.

Review: Great range, sturdy and bright. - First, this is not ultraviolet. Blue and Ultraviolet are not the same so complaining that it doesn't help with detecting blood or urine is just not understanding things. Blue light is blue light, ultraviolet iis ultraviolet simple as that. Blue vs Violet, get it? Ultrafire does make an ultraviolet light so if that is what you need get that but be aware that ultraviolet lights aren't designed to help you see things with normal vision and for illuminating most objects. Also, if you don't know but should take care to find out, very strong UV lights can quickly damage your eyes and skin and running around using them as cool flashlight is harmful. It takes very little exposure to strong UV to damage your eyes permanently, there is no fixing it. Now to these flashlights. They are really good for the price point. Being non-adjustable they do have a very bright center spot and then a halo of larger area. For an easy use light, they work well and are super bright with long range. I have the red and green and now blue versions of this light and they all work equally well. They do use up batteries pretty quick, you get about an hour so carry spares. Even batteries like EBC rated very high are depleted quickly, that is the price you pay for bight lights, there is no free lunch. A bright light, no matter how efficient will drain batteries quick. The only way around that is larger capacity batteries and given the size allowance there is only so much battery you can put into this light. I really like the dispersal area around the center higher intensity spot. Checking on things around the property doesn't have me changing between flood and spot, the balance between them in the illumination is really good. The Red is best for using it to avoid impacting your night vision. The green is great for seeing animals and it doesn't scare them off. The Blue works best if you are checking water ways like ponds, lakes and so on. Each has it's best purpose. A word about using a blue light to simulate official emergency lights (same with red). Doing so is illegal and sooner or later you will find that someone will catch you and then you'll have some significant events in your life, don't play around. I'm sold on Ultrafire lights, for less than many others they offer a very good light that although basic, provides great illumination and durability. A note to the maker - make a flashlight on this format (the larger 3 led head) in Yellow. They'll sell like crazy.
Review: Special batteries needed. - Needs special batteries, but other than that, it's a good light. It acts like a black light to see stains, and it treats fungus or rashes. Also great to find scorpions, if you are a desert hiker. The batteries and charger weren't that much extra, but make sure you get the right ones.

### ⭐⭐⭐⭐ Bright fixed beam in Blue!
*by A***N on March 11, 2024*

Very bright, makes oranges and pink fluorescent. Neat to shine kids toys. I wanted to use it to look for reptiles at night. They usually appear black under blue light. I did locate a small snake but the light is so bright it is hard to focus your eyes at close items. Worth the money if you have the batteries and charger already like i did.
