Convoy LED Emitter Types


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: Moderate, optimized for color accuracy.
    • Highlights: Great for photography or close-up work due to excellent color rendering.
  • 519A
    • Brightness: Moderate to high (~1000 lumens at max).
    • CRI: High (up to 90-95).
    • Efficiency: High, but depends on the drive current.
    • Highlights: Versatile with smooth beam and high CRI for general use and accurate color rendering.
  • XHP50.3 HI R70/R9050
    • Brightness: Very high (up to ~3000 lumens).
    • CRI:
      • R70: Standard (~70).
      • R9050: High (~90).
    • Efficiency: Very good for its output class.
    • Highlights: High output with options for either brightness (R70) or better CRI (R9050).
  • GT FC40
    • Brightness: High (~2500-3000 lumens).
    • CRI: Very high (~95).
    • Efficiency: Slightly less than XHP50.3, prioritizing CRI.
    • Highlights: Excellent balance between brightness and color fidelity, ideal for general illumination.
  • XHP70.3 HI R70/R9050
    • Brightness: Extreme (up to ~4000-5000 lumens).
    • CRI:
      • R70: Standard (~70).
      • R9050: High (~90).
    • Efficiency: High but generates significant heat.
    • Highlights: Extreme brightness for flooders or high-output flashlights.
  • SFT70
    • Brightness: High (~2200-2500 lumens).
    • CRI: Low (~70).
    • Efficiency: High, designed for throw.
    • Highlights: Excellent for long-distance performance with a focused beam.


Color Temperature Options

Commercial Link to LED Light Expert which explains the entire Kelvin based colors.



Quick Reference

  • 5700K: Cool white; maximum brightness but lower warmth.
  • 5000K: Neutral white; balances brightness and color fidelity.
  • 4500K: Slightly warm; better CRI perception and less eye strain.
  • 4000K-2700K: Warmer light; ideal for high CRI LEDs, especially for indoor or close-up use.

Selection Tips

  • For maximum brightness and throw, choose LEDs like SST40, SFT40, or KW CULPM1.TG.
  • For high CRI and color accuracy, choose 519A, B35AM, or GT FC40.
  • For balanced performance, XHP50.3 HI or XHP70.3 HI are great options.
  • Let me know which one you're considering, and I can help refine the choice further!

Convoy S11 Active Cooling Project

Image
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 ...

You Might have a Bad Batt

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...

Do I really need a Flashlight Cleaning Kit?

Image
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....
