This is a high output light so maximum is only a burst mode of maybe 15 seconds, depending on the battery.
Brightness levels are your choice of 150 different ones. It has smooth ramping. Brighter output gets warmer faster and has less runtime. Lower outputs run cooler and longer.
Thank you very much for your reply. FW3A.- I am not familiar.
15 seconds is very short. It is sad that a beautiful flashlight does not have the ability to increase the duration of work at maximum
No, it is a bonus that we get so much output from such a small light.
I have the xpl-hi version with a 30Q battery and measure 3,300 lumen at Turn On and 2,800 lm at 12 seconds. That is way too much power for such a small light. The laws of physics can not be changed. The huge amount of heat has nowhere to go.
This is why Turbo is not considered a regular, normal level. It is more of a short use, burst mode if you need it.
You can reduce the max output by using a high capacity battery instead of a high drain battery.
You can also reset the top of the ramp level to what you prefer for longer or shorter run times. Stock is about 2.8A which gives me about 900 lumen. I can change this to 600 lm or 1500 lm or whatever I want. The brighter it is, the shorter the runtime before the thermal protection steps in and reduces output.
Sorry, but there is another point of conflicting information. In the video, Martin says that it can easily take a protected battery.
BUT, on the Banggood website, it says “Max. length 66 mm.” in the battery section of the description. Is this just a cut-and-paste error from the FW3A description?
Received mine. Fantastic little light. Everything I love from the FW3A but with a side switch, a magnet and… a glowing bunny ! Clip is sturdy, threads are excellent, perfect anodization, magnet is strong. Diffuser was included. Very impressed so far.
