I actually just spoke with the Rayfoss owner and she was VERY helpful!
This was the conversation.
------------------------------------------------------------------
Deluxe: Hello
Rayfoss: Hello!
Deluxe: I was going to purchase a laser in the next couple days and had a couple of questions
Rayfoss: Oh...Ok..please tell
Deluxe: You do ship to the US correct?
Rayfoss: yes.
Deluxe: What will you be declaring the laser as?
Rayfoss: We will declare it as "electronic samples for engineer testing" or some time call it "Lights accessories for engineer sample".
Deluxe: Which do you personally prefer? The CSF or the FLX?
Rayfoss: This one RF532-200mW-FLX is better...As the size of the head of this type is a little bigger than CSF which enable it a better heat dispensation...but sure if you can obey laser's normal duty circle i.e. 30 seconds on and 5 seconds off CSF is also a good choice since it size is adjustable...The other thing CSF is lack is the shutoff windown of aperture which can prevent dust inside when you not use the laser
Deluxe: If duty cycle is not an issue, which laser would you recommend for me. I just want something that I can push and hold down the button, and the laser turns on. (Similar to a simple laser pen)
Rayfoss: both them are easy to operate as a laser pen...Just they are high power version not like laser pen duty circle is not so critical. Those laser torch are in high powered version which request user to attention on it's duty circle for a better heat dispensation ..Factually ,you can light it as long as you want but do this can shorten the lifespan of the laser ...
Deluxe: I would never leave it on continuously for more than 20 sec at a time. So overall, which laser do you think is better built and will last longer?
Rayfoss: if you can obey the duty circle I think both them are the same on performance...but I personally like "FLX".
Deluxe: And is that shutdown window very important?
Rayfoss: yes it is ..if dust go inside and dirty the lens then the beam dot will not so neat and nice.. But you can clean the lens by cotton stick and pure alcohol. This job need a kind of patient
Deluxe: The front metal cap can be taken off to expose the lens? Or do you stick the cotton stick through the small hole?
Rayfoss: There are 2pcs lens one is for focus the other is on the laser module. You can turn off the head to see the lens of the module easily. but for the second lens designed inside the head itself you need to clean it through the hole
Deluxe: So the CSF you can only clean through the small hole? Ahh, and I just figured out what you meant by the adjustable size. It looks like the CSF can use 2 different types of batteries. Is a battery charger included with this laser?
Rayfoss: yes..it is
Deluxe: Awesome. I will probably buy the CSF tomorrow. Thanks for your help. I'm assuming there is a place where i can add a note which says "Please place 5mw sticker on laser"
Rayfoss: Ok, I see thank you! the order form has the place to leave your remarks
Deluxe: Awesome! Thanks so much for your help!
Rayfoss: welcome!
--------------------------------------------------------------------
So as you can see from the conversation, both lasers seem on equal playing grounds if you stay true to the duty cycle. I am probably going to go with the CSF mostly because I like the design more and its seems to be equal to the FLX. I[m not sure what their name was, but the Rayfoss person was VERY nice and helpful! I would highly recommend them if you want good customer support!!!
Thanks everyone!
