hi
i am requiring illumination for a night vision device, and have decided to use a led based light source. it will be weapon mounted.
my plan is to use something like the osram SFH4750 emitter as i'm pretty confident others have used this for the same purpose.
now, bear with me, i'm a right noob at all this, but i'll ask for your recommendations for a host, or if there is something that fits the criteria that available off the shelf, i'm cool with that too.
many thanks in advance for your help....
1) How would you prefer to purchase the light?
____I will be mail-ordering or buying online, so this doesn't matter.
2) Budget: An easy question, but you may change your mind after answering the rest!
____Less than $150.
3) Format:
____I want a flashlight.
4) Flashlight-specific format/size:
____Every day carry small (2-4 inches).
____Every day carry medium (4-7 inches).
25mm body tube would make life easier...
5) Emitter/Light source:
____LED (known for efficiency, longevity, and compactness)
6) Manufacturer:
__x__I want to buy a light from a traditional mass producing manufacturer that is ready to go out of the box.
___x_I would consider getting a light that is pieced together (for example a "host" or flashlight body from one manufacturer, and a "drop-in" emitter from another source). Under the right circumstances, this path can provide more options to the consumer to meet specific needs, and can often be easily upgradeable as technology improves.
either really, would prefer to make my own
7) What battery type do you want to use?
____I intend to use rechargeable lithium (li-ion) chemistry. Feel free to specify a size if you know which size you want (14500, RCR123/16340, 17500, 17670, 18650, etc.)
123's preferable
8) How much genuine out the front (OTF) light do you want/need? Sometimes you can have too much light (trying to read up close up with a 100 lumen light is impossible).
____I want to walk around an unlit rural area (50-150 lumens).
____I want to illuminate my entire backyard or a campsite (150-300 lumens).
____I want to illuminate an entire field, the neighbor's front yard several houses down, impress my friends and neighbors, etc. (300-700 lumens).
i'd like to illuminate an area up to at least 50m out,
9) Throw vs. Flood: At what distance will you be most likely to use this light? Select all that apply.
____5-20 yards/meters (check out a noise in the backyard)
____30-50 yards/meters (I have a big backyard)
____50-150 yards/meters (I live in a very rural area/farm with wide open spaces)
i need even illumination without artifacts at 50. beam at 30m could be 5m. deffo dont need bright spot with spillage around the edges.
10) Runtime: Not over-inflated manufacturer runtime claims, but usable brightness measured from first activation to 50% with new batteries (Measured on maximum output).
____30-60 minutes (I have plenty of batteries just ready to be changed)
____90-120 minutes (Runtime is moderately important, but still not critical)
60min plus would be great, not a problem to carry batts. possibility of external power source stepped down from 12v
11) Durability/Usage: Generally the old phrase "you get what you pay for" is very accurate for flashlights.
____Very Important (Camping, Backpacking, Car Glove-box).
12) Switch Type and location (choose all that apply):
____I don't know.
remote switch would be a bonus
13) User Interface (UI) and mode selection. Select all that apply.
____I want multiple light levels. (Some lights have 5-16 light levels.)
14)Material/Finish/Coating
____I don't care.
simple lines would be nice
15) Special Needs/extras: Is there anything else you want or need that hasn't been mentioned? Select any below.
ability to change size of beam would be good, but need to keep an even illumination.
