  • LED vs CFL Bulbs: Color Temp, light spectrum, and more

    Putting some LED and CFL bulbs on the test bench to see what's better.

    This is one of the nerdier posts I’ve done, but since I’m unabashedly a nerd, and I hope many of you are too, I figured it would work.

    You see, I love LEDs. I think they’re fascinating in how they work, what they can do, and so on. As you’d expect, I’m slowly replacing the CFL bulbs in my house with LEDs.

    The thing is, not all LED bulbs are equal, and one of the biggest drawbacks is that not all offer the “warmth” in color temperature most of us love in incandescents.  So I put a few different LEDs on my test bench, measuring them sort of how I measure TVs, to see how they do.

    Curious? Well I was, hopefully you will be too.
