Why warm color and no 6500k pure white color?
Pure white is a "brighter" color at night

4100k should be just fine but this one looks a lot lower

What led is this using? I'm guessing its not crees XHP50 (19W) or the older XM-L2(10W).

Warm light, stronger penetrating
White light is brighter, but not that penetrating. Not as far as warm white light.

I know this from my other hobby retrofitting car headlights with hid projectors... Even with High quality Philips HID 4300kelvin and 5000 kelvin bulbs, while 5000k may look whiter and brighter our eyes cant use this type of light as effectively. Like Chatch said 4100k would be good.


(I have read somewhere our eyes cant see the light as good when its past 4600k, some thing to do with our evolution, from fires to candle light, just now are we creating bright lighting. Before it was only seen during lightning storms)

what really matters is what the camera sees. the bluer (like 4-5000k) LEDs are generally the most lumens per watt, but what is the cam most sensitive too? almost all cams have a Bayer filter, the filter pattern is 50% green, 25% red and 25% blue and that is why the green channel is the most sensitive.

that being said, the cams switch into B/W night mode so I dont know if they are still more sensitive to green.
