Guumbo's Flashlight Thoughts

Of course I do. When flashlight manufacturers package and send out a flashlight they often don't spend the time to clean up the threads on the inside and lube them properly. So I started smoothing them off and lubing them up. This makes the reassembly process so much more enjoyable to screw it together smoothly. Without the grabbing you feel from a rough set of threads. My process for a new light.... Remove head and tail from battery tube.  Remove O-ring from threads Check for rough spots on inside and outside threads Sand with green scrubby to smooth out.  Wipe with paper towel, use Q-tip if tight spot, interdental brush if even tighter Grease threads, O-ring divot at end of threads and O-ring with Q-tip with Super Lube Put O-ring back on, ensure outside of O-ring is still lubed Screw on cap or tail and enjoy the smooth action Double check the switch still works If excess lube, wipe off with a paper towel In the kit above I keep the following....

Below are simple rules to follow when choosing a Convoy Light Scroll down to the specs Look at the reflectors which come with each led Convoy C8 Scroll to the bottom to see the specs  SMO = Smooth = thrower OP = orange peel = floody Domed(aka tiny convex lens) for floody dedomed for thrower Decide which one you want and pick 2.  Google led VS led and google will tell you which one is better for which Example: LHP vs SFT-42R Bigger led model numbers GENERALLY means larger LED whhich will be floody, smaller means thrower If you don't buy a batt from convoy get one on their list of options Generally the best will be Molicell for power output and Vapcell for runtime/mAh will be the best Try these for some reputable battery dealers 18650batterystore Vapcelltech Liionwholesale When the LED's say they get hot you'll probably want a larger host to dissipate heat better Hosts with lots of fins will dissipate better or just plain lots of mass will help as well Large hosts for heat di...

I have several Convoy S11 flashlights in various configurations. All are fine but only function on high for a few minutes before stepping down. I also have a Lumintop Mach 4659 flashlight which I got specifically for the active cooling fan. I was quite disappointed with the runtime performance. With a battery that size and active cooling I'da thought there would be much better runtime. Maybe I was expecting too much performance benefit when running on turbo. So I thought I would further my flashlight modding hobby and try to build one myself. I started with my Convoy S11's and chose a cooling fan built for RC Car electric Motors . Then I used thermal tape to keep it on the light and properly transfer heat to the sink. The sink was slightly wider than the flashlight. So I bent it in slightly until it fit snugly on the flashlight. Next was power. I ended up using 3 different types of LIPO batts all for what I assume is some kind of drone appliation. At first I used a ready made ...

Bad Batts See  Thermal Runaway Batteries - Re-Wraps, Worn Out, Fake Do not buy Lithium Ion batteries from Amazon, Temu, AliExpress, and Walmart. If you can't find a manufacturer site like XTAR , Vapcell or Molicel that's a good indicator... You might have a bad batt. If the manufacturer name is nothing but 4 random letters strung together ( Ex: DQGG, CBJJ, QOJH, etc. )... You might have a bad batt. If the name contains in Fire(EX: Skyfire) except Surefire chances are it will soon be engulfed in.... fire... You might have a bad batt. If its hard to find the manufacturer on the battery label... You might have a bad batt. If its an 18650 and has 9900mAh... You might have a bad batt. Any batt which has over 6000mAh (21700, 26650, 26800) 4000mAh(18650 or less) indicates…  You might have a bad batt. The current max mAh is usually a VapCell so if the capacity for the battery type is way more than their max, chances are … You might have a bad b...

Beam Types See Nitecore:  The Anatomy of a Flashlight Beam  for details Floody  - a wider beam intended to illuminate a large area Spotty / Thrower  - a light which throws a tight beam a long distance with a small spot at the end Blended Beam  - A beam composed of both floody and spotty features.  Reflector Types Smooth  - typically used for throwers to direct the beam down range in a tighter spot Orange Peel  - typically used in floody lights. The texture causes the light to spread out at various angles from the head of the light. Lens Types The lens will either be a flat piece of glass which relies on the reflector the change the profile of the beam. An aspherical, typically flat on one side and convex on the other. Or a TIR lens. TIR - T otal Internal Reflection  -  A  TIR  lens is an optical lens built on the principal of  (TIR) .  TIR lenses are often cone-shaped and rotationally symmetrical, with a refracti...

This is an unofficial page created and maintained by me without authorization by Convoy . I owe this list to another user on Flashlight Enthusiasts . When I find their name I will given them appropriate credit. This is NOT a complete list. LED Types SST40 Brightness: High (up to ~2000 lumens depending on current). CRI: Typically lower (~70), designed for brightness over color accuracy. Efficiency: Good at high drive currents. Highlights: Popular for throw (long-distance beam) due to high output and small die. SFT40 Brightness: High (up to ~2200 lumens). CRI: Typically low (~70), optimized for throw. Efficiency: Comparable to SST40 but with a de-domed design for enhanced throw. Highlights: Excellent thrower LED due to focused beam. KW CULPM1.TG Brightness: Moderate (~1000-1500 lumens). CRI: Low (~70). Efficiency: Very high, designed for throwers. Highlights: Extremely tight hotspot for maximum beam distance. B35AM Brightness: Moderate (~600-800 lumens). CRI: High (95+). Efficiency: Mode...
