    MoveLater2 LED light bar colour temperature

    I am looking at purchasing a LED light bar for my car. All the lights that I have looked at are 6000K. I would prefer lights that are around 4000K or 4300K. Are these available?

    ... Keep looking....

    Problem is, the vendors mostly parrot the info from the factory...which may or may not be anywhere close to reality..

    Assuming they're within the same Numbering System... for general use - up close and 'arms length' around bush, scrub and trees - you are better off with the warmer colour LEDS. 3,800 to 5,000 degrees Kelvin.
    These will give you more detail and finer shapeing/texture in amongst the foliage, and a large green highway roadsign won't burn holes in your retina... in the same way the more 'Daylight' / Cool white colours do...

    Its all very well to throw out gadzillions of lumens, blinding zombies, the International Space Station and possums alike... but bear in mind that 'Reflectorized' roadsigns are designed to... Reflect. - Right back at you.

    That might be why Aaron is asking.

    I remember Todd (R2D2) demonstrated a few at a Wombat camp. He might know.

    A guy in a 4wd shop explained things easy to me.

    If the light has a lux rating as opposed to all the other bull**** light outputs the led light manufacturers use , it is simple.

    1 lux is the amount of light needed to read a newspaper.

    Some manufacturers are now giving lux rating over distance...eg 1 lux at 400m.....that mean s you could read a newspaper at 400meters etc.

    It's what you want to see in your vision , not what colour or temperature or wattage that's important.

    Now if all manufacturers gave us their light outputs in that way it would be very simple.

    I have no idea what a kelvin is , nor a lumen and watts are how much power you waste.

    I couldn't even see a newspaper at 400 metres, forget about reading it.

    Color rendering can be hugely important. It affects strain on the eyes - note how staring at a blue-white computer screen sitting in your blue-white lit office strains your eyes more than when you're outside?

    Unlike what is often marketed, its not just about brightness. Check out this article for a little more info (its not that in depth).

    The fyrlyt website itself goes into way more depth about light colouring and how LEDs have trouble rendering orange and browns (ie the colour of animals you arw trying to avoid) it is marketing but there is truth behind it.

    Yes, i have got my info from the fyrlyt website, but its the place i found out about it in the first place (thanks Tombie) and is the easiest reference to find.

    Cheers

    Amen and Amen... A good primer and easy to understand.

    My background:- Photo-lithographer, - electronic colour scanning, colour correction and printing. Photography, colour film processing. - So yes, I've got more than a vague idea about 'colour' etc.

    Everything above is relevant and important, the least important (ok, taken to extreme...) is 'mega-thousands of LOOOOMINS' which are best used for lighting campfires... as in First pic, - fourby's lights shining on the fire that was lit by it's spotties....

    Second pic is the kind of illumination that would be both comfortable AND safe... over a long period of time. Gravel looks reddish/orange, like REAL gravel, the contrast of brown/green around the letterbox (?) half-way up the LH side is better... as is the brilliant (sorry!) Depth-Perception in the foliage RH side under 4X4 logo... Compare these and other areas between Pic 2 and Pic 3 (the "whiter" or more 'Blue' colour rendering...)

    Now imagine the picture is moving - which is what happens when you're driving down that road... Instead of studying the pics, just glance at them and see (!) which one gives you the most information about shape, contrast, depth etc in the shortest moment of time.... Your steering, speed and braking is wholly dependant on that data... How BRIGHT it is is less important because, unlike the camera used to record those scenes, your eye & brain will adjust for light levels... though pic 2 demonstrates a common failing of toooo much light... directly in front of you.... effectively dazzling and causing your eyes to 'stop down'...thereby 'darkening' the extreme end of that beam..which is already lighting up the possums, so it cannot be lowered any more.
    Thats' just for starters...

    In shrt, FLRLYT have got it Right, IMHO.

    ....sorry... I should have said if you were sitting AT the 400mtr mark you should be able to read your paper....

    The site hasn't been updated in a while but there's some good info here: Daniel Stern Lighting Consultancy and Supply

    The thing that concerns me about light bars, especially cheapish Chinese ones, is just how well (if at all) they are designed for light pattern. Quality manufacturers spend a lot of time and money designing reflectors and lenses.
