The biggest differences between the two ring lights are the types of power sources and light output. The Cordless Ring Light Pro has a built-in lithium ion battery, whereas the 18" Ring Light is powered via AC and does not come with batteries. If you want to power the 18" Ring Light via a battery, you will need to purchase two external NP-750 batteries separately.

To calculate the objective spot size, multiply the wavelength by the focal length, then divide the result by the product of π and the beam diameter.

Honestly this light is amazing!!! I didn’t use the stand I actually bought a wall arm and attached the like to it and it’s so bright and gives even brightness which I need!!! I’ve gone through so many ring lights from Amazon to other brands and this is by far the best one I’ve bought so don’t think about getting it. Do it!

The objective spot size refers to the diameter of the focused spot of light produced by an optical system, such as a microscope or a laser. This spot size is crucial in determining the resolution and precision of the optical system. A smaller spot size allows for higher resolution and more precise measurements or cuts, making it essential in applications like microscopy, laser cutting, and optical data storage. The spot size is influenced by factors such as the wavelength of the light, the focal length of the lens, and the diameter of the incoming beam.

Also, the Cordless Ring Light Pro has an output of 1500 lumens, whereas the 18" Ring Light has an output of 528 lumens. While both are portable for on-the-go use, the Cordless Ring Light Pro is also substantially lighter than the 18" Ring Light.

The following formula is used to calculate the objective spot size for a given wavelength, focal length, and beam diameter.

I received my light yesterday and immediately set it up and started photographing items to add to my website. The light was great and gave me the proper lighting that I needed to showcase my items without any problems. I love the ability to adjust the lighting from warm to cool and not have shadows. I'm so happy I decided to up my game by purchasing this light.
