I am thinking about ordering a Dereelight 1SM-2 module but I have a question about using 18650's with it.
On Dereelight's website they say the this drop-in will have constant output at 4.5~16V does this mean that if I use a 18650 I will not have any regulation at all or will I only have regulation until the battery voltage drops below the vf of the LED?
I am going to be using this drop-in in a weapon light so I want it to be able to use 18650's and CR123's but then again I want it as bright as possible for a long as possible so...
Also if anyone has any suggestions as to what other drop-ins/lights that are out there I'm all ears, just please keep in mind I have a $50 budget.
Thanks for any info/input.
