  3. Dear members,

    Our membership (like our country) consists of people from all walks of life; different in far more ways than can be listed here and each with a different view based on their experience of life - regardless of their colour, religion or cultural heritage. Every single person in the UK has been born of mixed race – we are a multi-coloured and multi-cultural country.

    As many of you are aware there are a handful of individuals amongst this membership that persist in making provocative, inflammatory, racist and otherwise offensive comments. This has been happening across the forum to a certain degree but is most especially prevalent in the Adult section.

    The moderation team has tried to stay on top of this, however unfortunately because of the ‘offensive’ nature of much of its content we don’t monitor the Adult section quite as much as perhaps we should. As a result much of this behaviour has gone unnoticed unless it has been reported to us. While the team always intended to take a "light touch" approach to the Adult section it would seem that some people aren’t quite adult enough to be left unmonitored after all.

    This behaviour is, and always has been against Forum Rules as well as the specific stipulations of the Adults forum and it will no longer be tolerated. We feel it's time to draw a line in the sand and as such from this point onward offenders will receive an immediate and permanent ban from the forum.

    In order for us to achieve our goal of restoring the forum to the friendly and tolerant place it once was, we ask that ALL members be mindful of the content they post and help us to stop unacceptable behaviour by using the 'Report' tool at the bottom of any offending post - the results of which can be seen only by Admin/Moderators.

    You should all receive a copy of this message by PM.

    Hi,

    Im looking to buy a torch with either a red led or a red aspect for spotting.

    the more distance the better, i have a nightmaster 800 IR and im thinking of buying the red led for the unit.
    just wondering is there better out there?

    i do have nightvision but i want to try some experimenting with a range finder and a red light.

    Cheers

    A red led will perform better than a filter on white light. I'd favour a second torch rather than having to swap the pills, might even be cheaper as the nightmaster stuff isn't cheap.

    Hi terry,

    £35 for the pill for the night master.

    Any recommendations on a good torch?

    cheers

    That's a long way for a torch. I don't think that you'll get that range unless you're using a camera/telephoto lens to spot with because there's not enough light from a single led to reach out that far to see with the naked eye. The torches can be fitted with a large lens to get the focus down really tight for long range use but that adds a lot to the size and weight and a fair bit to the cost.
    I don't know what they claim for the NM800 with their red led, I believe the 800m claim is for a white light.
    The torches that I sell are much the same performance as the T20 type and I've not had the opportunity to spot eyeshine beyond about 250/300 yards which I can do with the red led but whether it would be possible beyond that I don't know. The Cree white led that NM use is probably the XML T6 or U3 and they can be run at about 10 watts but the red/green versions are only 3 watts so a lot less light available.
    Don't really know what to suggest to guarantee the sort of performance you want from a torch unless you go up to a big lamp.

    i was hoping for something small so i can attach it to the side of a range finder, maybe im asking to much :)

    i suppose the only way im going to get that sort of range is with something like a tracer?

    If you look at led torches they mostly use the same emitters, as I mentioned earlier the favourite white one is the Cree XML family and they can be run up to about 10 watts giving around 1200 lumens - these are real lumes not the Far Eastern ones which are only about half the size! Given that you have a limit on the actual light output you gain performance by having a better lens, those that come with the cheaper torches are fine for their intended use but to get more range means better quality, properly ground lenses and these get large, heavy and expensive. If you go for a single colour then the light output drops to around 120 lumens which is a lot less.
    It's possible to get torches with multiple leds fitted, these generally have a tiny lens fitted to each individual led but these are not a narrow angle but will put a lot of light onto an area at 100 yards or so, maybe more but the light intensity drops off quickly - if you double the range the light intensity is reduced to 1/4. The other problem you start to encounter at long range is atmospheric pollution from dust, mist etc which also affects the beam.
    It's possible to make high powered lamps to go with vehicle spotters where you have plenty of 12 volt power and a vehicle to cart it all around, these will use multiple leds to illuminate an area for spotting rather than a single tight beam which would really be more suitable for shooting.
    The other problem with high power is battery life (and heat generation), these 10 watt leds draw over 3 amps so a single 18650 cell would probably give no more than 45 minutes at full power.
    Your idea of using a red torch with a rangefinder isn't something that I've heard of anyone trying, there are people working on rangefinding at night but, it seems, without much success so far. I presume that you are intending to use this for foxing but I'm not sure that it would work well enough to get an accurate reading with a small target which isn't very reflective. What I have seen so far involves watching the target using a night vision camera which will show you where the rangefinder laser is hitting, basically you would have a nv spotter attached to the laser and lined up so that they are both looking at the same point. If you have a screen to view it you should be able to get enough light from the screen to read the rangefinder.
