For those of us still teaching and receiving lessons on line, being well-lit is a high priority. I want my students to essily see my expressions and details in my vocal posture- and I want my teacher to, as well!
What's the solutions? A cheap, bright and USB powered ring light that plugs right into your computer and can be set to bright white, mix or warm. I prefer warm. I have bought several 6 inch in diameter version, varying in price for $8 to $15 (for my various studios) and I like them all. Check them out here: Light
I hope this helps you stay well-lit, preofessional looking, and beat back some of those dark-days blahs.
