Functionality / Comparison / Testing of Smart bulbs

In searching through this forum I found a link to this website:

It’s got some great information, but its a bit out of date (hasn’t been updated in around 2 years).

There is a bunch of stuff that I thought was true, but didn’t have any hard data on such as:

  • The brightness change as you move through from Cool → Neutral → Warm color.
  • How much brightness drop off is when you choose a single color hue (and that is not uniform).
  • How close the colors are to the theoretical version (color shift).

So it’s really great to be able to look at that.

Some stuff I would like to have seen (that isn’t present) is:

  • If the bulbs smoothly transition from “Color Temp” to RGB colors.
    • If the bulb can match color temp brightnesses when in RGB mode.
  • If color can be set when off.
  • How transitions (from one color to another work).
    • Does the behavior differ when transition from off → color vs color1 → color2

Are there any other sources/resources that:

  • Cover those additional questions?
  • Are more up to date / have additional bulbs?
