I've been searching the internet for a definitive answer but can't seem to to find it. I have a project that will essentially be an LED desk lamp, but I'm not sure what type of LEDs (size, brightness, luminosity, etc) to use in order to get close to the brightness of an average desk lamp using a, say, 60W bulb. What would be the best type of LEDs for this and how many should I use? Also, it I were to have the lamp change colors, would it be best to use RGB LEDs and change the color that way or simply adjust the values or separate red, green, and blue LEDs?
Thanks for he help!
