Please recommend IR lamp for exterior driveway and backyard

[MakeItRain]

Can someone recommend (on Amazon) what they are using for IR illuminators to supplement their Dahua IP cameras?

I am mounting a few 4K cameras and due to darkness, I want to be able to supplement them with more higher powered IR.

I like to keep costs down maybe $20-40 max if possible.

There are recommendations in the Cliff Notes.

I'm currently testing this one and it's doing alright.

Fabolous. I might just get that one.

Thanks

Cut rated distance in 1/2 for usable distance on most all illuminators..

I have three of these for about 2.5 years. No problems and very bright.

I have this one, which is well made. It's appropriate for more distant shots. It's probably in the 24 watt range. It's best for a high camera.

I would stay away from the high count low power IR LEDs. Power hogs and reliability issues just due to part count. Stay w/ the higher power low count (qty 4) IR LED illuminators.

Does anyone have a good feel for the light output per LED at some useful distance as it relates to camera shutter speed? I am not sure that LUX is a good measure at 850nm, as i expect that the camera is way more sensitive to 850nm than to visible light of the same lux rating (just a guess), but a LUX meter is what i have so there is that. What i was thinking is this: does one 1W LED produce about the equivalent of a 100LUX LED bulb (or that amount of sun) at say 25 ft from a camera (assume a Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)) if both are in B&W mode? Has anyone done any crude comparing of this?

It would be nice to have a rough feel for how fast the shutter/low the gain can be for a given amount of IR, to decide what to buy. I have a couple of large (very dark at night) indoor spaces, and was thinking about options.

Note: One nice thing about external IR light is that it is off angle from the camera, thus increasing the depth of field and reducing the hot spot glare.

p.s. I did not mean to hijack this thread. I can start a new one if that is better. This post got me thinking about this again...
