As a tech fan, an on-off switch is too simple. I want to be able to adjust the brightness and "color" like the volume of my stereo. I never put my stereo to 100% because we figured out long ago how to do affordable loud speakers that are uncomfortably loud. Why haven't we figured out how to do affordable lights that can be tuned to uncomfortably bright? I want Caribbean beach bright as my 100%, with an "equalizer", to tune the heat/reading comfort/UV/color to my liking.
To me it feels like any advance in light bulbs is only on the lumen/watt scale. How long until we have a one million lumen broad spectrum LED configuration that doesn't cost a fortune?
