From a November 2007 Macworld blog review, by James Dempsey, Creative Guy blog.

"Knoll Light Factory can be used to create more than just exploding planets in space—try enhancing sunlight in your landscape photos, or making that candle in a photo of a warm holiday scene brighter and more... [I]f you work with a lot of images and like to bring a little extra to the lighting, this plug-in is well worth having."

From a January 2008 review of version 2.0, by Anthony L. Celeste, in Shutterbug magazine.

"Knoll Light Factory is focused on creating lens flare effects, one of the most commonly used effects in both photography and film... As you may know, Photoshop does contain a Lens Flare filter, but it is extremely limited in ability... I chose Knoll's lens flare plug-in for this article, because it is one of the most powerful and customizable lens flare plug-ins on the market."
