Howdy MT7, and welcome to CPF!
Some very fine questions, let me see if I can help give you some thoughts from our perspective.
hello,
I bought the Led Lenser MT7 two weeks ago,and It's one of the best flashlights I ever had
Most folks have never experienced a good LED light, so when they get their first reasonably good LED light they are amazed, I know I was.
they have many functions as strobe,SOS,boost and blink-even most of the surefire flashlights haven't strobe mode
While SOS and blinky type functions seem cool at first, think about how often you'll actually use them. Depending on how they are incorporated in the UI (user interface) they can actually be a distraction. Imagine every time you use your light having to scroll through the SOS and other blinky modes just to change from high to low light levels...... arrrrgh. Manufacturers like Surefire focus their efforts towards building bullet proof lights rather than providing features that will rarely, if ever, be used.
Led Lenser's flashlights need only few cheap aa batteries,not like the 123A that costs a lot of money
First of all, those "cheap" AA alkaline batteries can leak corrosive chemicals into your nice new light, which is one reason most CPF members avoid them. We prefer to use rechargeable cells which for the most part won't leak and ruin our lights, and also allow us to always go out fully charged.
Also, the higher voltage CR123 (and similar) batteries allow us to have small lights that will run very bright for longer periods of time than cheap AA alkaline cells.
If you spend some time here you'll find that there are some lights that can run on both, giving us the best of both worlds, a light that can run very bright on a small high voltage cell, but that can also run at a lower brightness level on a common AA alkaline cell if ever needed.
and the advanced focus system of led lenser is awesome
Many CPF members feel that most built in focus systems tend to compromise the beam quality in order to provide both flood and spot. They feel you get a better quality flood beam with a light dedicated for that, and a much better spot beam with a light dedicated for that. It's really a matter of personal preference.
So why a lots of people hates Led Lenser?
It's not a matter of "hating" LED Lenser lights, but this is a forum dedicated to flashlights, so of course we discuss every light's strengths and weaknesses as well as their value compared to other available lights.
So, enjoy your fine new light. I'm sure it will serve your needs well, and while you're enjoying it please feel free to continue visiting CPF. If you're like most folks who visit here, the LED Lenser MT7 won't be the last light you buy
