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 and 940nm infrared LED illuminators?
850nm Infrared Lamps
850nm is widely used in night vision equipment as it produces a strong illumination effect, enabling night vision devices to capture clearer images at longer distances. This type of infrared light can provide enough brightness to help night vision devices capture more details in dark environments and is suitable for situations that require observation over a wide area.
However, due to the shorter wavelength of 850nm, which is the light that can be detected by the naked eye, the chances of being detected when observing a target increase compared to 940nm infrared lights.

940nm Infrared Light
The 940nm wavelength of infrared light is well within the infrared spectrum, which is virtually invisible to the human eye. This means that 940nm infrared light beads are more covert, a characteristic that makes 940nm infrared light beads ideal for applications that require a high degree of covertness, such as security and military.
Although 940nm IR lamps can provide a certain degree of illumination, the observation distance is shorter compared to 850nm IR lamps.

In short, as one of the core components of night vision devices, the performance of infrared lamps directly affects the overall effect of night vision devices. By understanding the characteristics of 850nm and 940nm infrared lamps and their applications in night vision devices, we can better choose the right night vision equipment for ourselves and enjoy the infinite possibilities brought by the night.

Warm Remind:
This bulb or any other IR source 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.
