The bulb provides enough IR to illuminate a good size room by bouncing the light of the ceiling (provided the ceiling is light colored), doing that will eliminate most shadows.

What's the difference between 850nm、940nm and 980nm infrared LED illuminators?

940nm infrared LEDs are virtually invisible to the naked eye. These LEDs produce no light that the naked human eye can see. The light from these LEDs can, however, be picked up by most infrared night vision cameras.
However, it should be noted that in a completely dark environment, the 940nm LED chip can be seen faintly as a very weak red.
But The 980nm is 100% total invisible in pitch black.
An 850nm LED produces a visible red glow but will illuminate stronger than a 940nm LED of equal power. This is how a compatible illuminator with 850nm LEDs will illuminate much better than a 940nm. However if there is a need to be discreet, 980nm and 940nm are the better choice due to its invisibility. This bulb is also suitable where there is a need to illuminate a specific area, since it will work in most light fixtures disguising and aiming it is easy.

It is meant to replace your IR night vision camera’s glow in the dark LEDs with no-glow invisible IR.

Warm Remind :
This bulb or any other IR source 980nm, 940nm or 850nm will not make a non-night vision camera, (as well as a smart phone camera) night vision capable. Day time cameras do not “see” infrared light.
