Check the review by zeroair.org. It holds around 2000 lumens for 50mins before gradually declining to around 1800 lumens at around 70 mins. Not many lights are capable of that in this class. The convoy m3 sustains around 1400 lumens
Dave1010 got his M3-C to hold 1600 lumens for 1.5 hours. Actually almost 2 hours starting from turbo.
From zeroair’s review I’m seeing 81 minutes to 1576 lumens with the TC20 V2. This is with cooling. This is good no doubt.
Something is wrong here, the pictures shows the V1 with Micro USB Port….
Agreed, very good efficiency from the M3-C, although you’re understating the performance of the TC20 V2 a bit with that description as it’s fully regulated for 50 minutes at 2000 lumens before gradually declining. Actually comparing performance off both, it’s very close to proportionate efficiency. A little over 100 minutes for the M3-C at a lower output (around 1600l) to around 70 minutes of overall higher output (2000 lumens)would be around the same, given leds get less efficient the harder they’re driven. The M3-C however has a very impressive turbo thanks to it’s mass.
The problem with “cooling” during reviews is that it often doesn’t represent real world situations, though of course even real world situations can vary between 30C and no wind, and –20C with wind. A bit more description of actual cooling setup would help review readers know how accurate/inaccurate a review might be to their use cases. I don’t really want to buy a light reviewed to sustain 2000 lumens to find in reality it can only sustain 1000.
Agreed StephenK, I believe zero air just use a light fan to simulate outdoor airflow, at least I recall this being mentioned on one or more of their reviews.
When I use my M3-C in winter I put it on turbo and take 10 - 15 minute walks with little or no step down. Pretty incredible. I can do this about 3 times using the 26800 before it won’t hit turbo anymore. The driver emitter combo is the best so far in my opinion. No doubt the TC 20 V2 is equally impressive. Beats the FET soda can lights all to hell.
Too true arrived today definitely a fried egg, not a patch on my Rofis MR70 which I unfortunately lost.
