The YC Onion Energy Tube is a fun addition to my studio gear that I use when getting into commercial photography, fine art and audiovisual technology get in The light is small enough to be comfortable but bright enough to be effective. Love the fact that I can use the RGB mode/click the 360° color wheel while learning to color to showcase my own hues. The variable color temperature from 3200 to 6500K also allows me to teach the color temperature and mood effects that can be created. I think it's best to use light for portraits and still lifes. However, I'm really excited to find a way to use light for night photography.
