WHY B1 WORKS
Purpose-Built for Blood Tracking
The FIELDLUME B1 is designed specifically for low-light blood-trail tracking rather than general-purpose illumination. Its filtered light helps create stronger visual separation between subtle blood traces and distracting natural backgrounds such as grass, soil, bark and dry leaves.
40+ Layer Optical Filter
At the heart of the B1 is a custom optical filter with more than 40 precision coating layers. These multilayer coatings selectively control portions of the transmitted light spectrum, helping reduce distracting background colours and improve visual contrast during tracking.
The filter is an optical aid rather than a chemical detector. Results can vary with terrain, moisture, ambient light and the condition of the trail.
Three Output Levels
Choose the level that matches the search. Low provides controlled illumination for close-range ground checks, High expands coverage for wider-area scanning, and Turbo delivers maximum filtered output when more light is needed.
Low — 30% · High — 80% · Turbo — 100%
6000mAh Replaceable Power
The B1 uses a high-capacity 21700 6000mAh rechargeable battery, providing more available energy for longer tracking sessions in the field. The battery is replaceable, allowing you to carry a spare for extended use rather than relying on a permanently built-in power source.
A battery, external charger and USB-C charging cable are included.
Built for Field Conditions
A textured anti-slip grip provides secure handling while scanning uneven ground and vegetation, while the aluminium body is designed for regular outdoor use. IP65 weather resistance adds protection against dust, rain and splashes when tracking conditions become wet or unpredictable.

I would say I am not an experienced blood tracker and this has been my first year of tracking blood. Before this light I lost 2 deer due to the blood trail. I bought this light and used it to track a trail and was able to find my deer. I feel confident ins aying that if I did not have this I wouldn't have found it on my own. Once I left out the woods and hit grass I knew I would have a difficult time. Once I seen a blade of grass feom the woods I started there. I flashed my light and seen some more blood. Then from there I kept on tracking and found my deer. Was very thankful for this light.
This is a very useful light for tracking blood trails at night or in low-light conditions. The light is bright, easy to use, and the different color modes help make blood easier to see on the ground and vegetation.
I bought this flashlight for blood trailing while hunting, and the experience has been excellent. The light definition is very good, helping to clearly highlight trails on the terrain. Best of all, it comes ready to use—including a rechargeable battery and its own charger with a USB cable—so you don't have to hunt for separate accessories.
This B1 blood tracking light is a hard carry for any hunting fam. The high-definition tracking light functionality is amazing; it makes blood trails glow for easy recovery, which is great durability in the field. It’s a creative tool for hunters. Important: This is only for tracking deer blood; it is not going to locate scorpions in your yard or help you find lost keys. Tiny con: the battery runs down faster than expected.
Work good
I gave it a 3 because I haven't had the opportunity to use it yet but it seems to be built really well
Thanks Wayne, enjoy the first outing
This Flashlight is super high quality! It is easy to assemble, and it is nice that it comes with a rechargeable battery! When using the light, it gives off a really strong beam that will be great for when you are trying to track a trail while hunting. This is a great light that I am glad that I bought!
