First thing I want to take care of is identifying what the Monteer 3500 is, a thrower/spot light! Magicshine provides enough information to identify its beam characteristics if you read all the tech. specs. (see circled info on below screenshot), know what they mean, and take the time to put 2 and 2 together. Highest candela rating (light intensity) and throw distance of any MS light + the use of SST20 are clearly shown but Magicshines description of the Monteer 3500 as the entry level Monteer light is a little vague and if you aren't familiar the SST20's high throw/narrow beam characteristics (in spite of having the same optic beam spread as the much floodier larger Monteer's) I can easily see someone thinking the 3500 is just a less powerful floody 8000/6500/5000 so I wanted to clarify this point!
So it's a thrower and a very good one. Initial turn on lumen and max lux numbers are astounding but output degrades quite rapidly at first finally settling to a stable level about equal to a Gloworm XS after the first half hour. 108.5 gram lighthead weight is also similar to an XS so the Monteer is a ligit low cost competitor for the XS or any other high putput/high throw helmet light. As a bar light the Monteer 3500 is far less capable IMO. Beam is too narrow for my taste for MTB riding but OK for path/road use.
As you can see from the above chart the output degrades quickly from its almost 5000 lumen turn on point. Some of the loss is from heat but most is programmed into the light. Lighthead seemed to shead heat very well and cooled quickly when turned off so thermal path must be pretty good. If you don't mind shutting the light off every half hour or so you also can operate it at higher levels as this restarts the program. A quick off/on operation will bump the output around a 1000 lumens but this will also drain the battery quicker and probably not necessary since its stable levels are excellent. Test was run with the included 5200mAh battery so high mode operating duration can easily be extended with the use of a higher capacity battery. Battery is also usb charged and can be used as a powerbank which is nice.
UI has its good and bad points though mostly good. Lots of mode choices but easy to maneuver through with single and double clicks. Mode button is easy to find, consistent and accurate with a light touch that only takes 1 finger to operate. Bar mount takes a tool to install/remove but very easy to use and adjust and garmin interface (Gopro adapter also included) is quick and simple for lighthead removal. The bad is a flashing mode in the main program that makes no sense for this type of light to me!
In conclusion the Monteer 3500 is an excellent high performance helmet light. Narrow focused beam that helps it for helmet use also limits it usefulness for off road bar use but there are other Monteer models that excell for that. Magicshine accationally sends me lights to review but this one I purchased myself and have no regrets and I can't imagine anyone will be disapointed with it if used for its strengths!
