The Bedtime Bulb had issues. Second, I don’t feel the spectrum of that lamp is really world leading, or something that’s really worthy of an international standard. The overlay of of an incandescent lamp in figure 3 shows the Sunlike as being on par to slightly worse in terms of blue. I want better then stock incandescent. I also want warm light that looks like a flame or a dimmed incandescent. 2700K dimmed is not warm enough for me.
so, only 2250k with 35v COB LED
