Trustfire TR-J20 12xCree XM-L T6
My first powerful multi-LED flashlight was Trustfire TR-J18. After about a year i was ready to take a step to another level… After reading relic38’s review Here i was pretty convinced to buy one, but then i suddenly discovered FlashPilot’s review of TR-J20 and immediately fell in love with it. It had same LED count, it was shorter and it looked even better “heatsinked”. So… finally… This is the ultimate flooder i was looking for :love:
I ordered it for 99,20 (excl. batteries) from fasttech.com. Flashlight was modded with 1 ohm resistor. Ceiling bounce test shown 20-25% increase. For unmodded review + teardown and much more (much better review 
) see FlashPilot’s topic Here
Dimensions:
DEPTH 92 mm
HEIGHT 340 mm
WIDTH 92 mm
WEIGHT 1359 g
Pros:
- Excellent built quality
- Great heatsinking
- Packaging
- Robust body
- Clean and smooth reflector
- Reflector glass without any scratches
- Sufficient inside wiring
- Design
- Water resistant
- Robust and solid tailcap switch
- Mode memory
- And more…
Cons:
- Dirty reflector glass (already cleaned)
- Useless emittor spacer rings
- Unnecessary SOS/Strobe modes (in such huge flashlight)
- Not many charger options for 32650 batteries
- I has slightly cooler color temp than my TR-J18
I think it’s useless to describe how bright this flashlight is… It’s obvious… Just look at the size of that think! It can compete (maybe it’s even brighter) with my Skoda Superb II Bi-xenon headlights (low+high beams) and that’s 180W (2x D1S + 2x H3) of light in total. We compared it even with friend’s Golf mk4 halogen lights. Well… The car was totally humiliated by LED power. And if you still don’t believe, look at the comparison shots lower 
In comparison pics the TR-J20 looks more robust (well that’s surprise!). If i look closely on both, TR-J20 feels better machined. Also glass and reflector on TR-J18 came a little scratched compared to TR-J20. Well in short… Both flashlight’s powered OFF are very similar (another surprise, since they came from same factory) both have SOS/Strobe (sadly). And that’s it. Let’s see comparison shots
32650 batteries look badass! However there aren’t many chargers on market capable of charging three batteries at once. I personally use TR-008. While it has many drawbacks (overheating and noise) it’s great charger for the price.
Measurement (measured with extremely cheap and crappy multimeter). Crappy multimeter shows (very likely wrongly) 12,45V x 5,82A = 72,5W. Sorry i don’t have anything better

Enough talking. Here comes beamshots! Everything is taken with iPhone 5S (locked exposure on TR-J18’s beam).
Beam comparison against white wall (0,5m). From left to right: Trustfire Z5 (just for fun), Trustfire TR-J18 (unmodded), Trustfire TR-J20 (1 ohm resistor mod). Notice huge light splash around TR-J20’s beam.
