This is assuming RGB LEDs, for specific colors, blue is actually more expensive than red.

oh that’s interesting, but I think colour changing RGB LEDs are going to become, or already are more common than single colour bulbs.

For this data the “Difference achieved in wattage consumption on new A60 White and colour ambiance E27 1100 bulbs compared to 4000 K at 100% brightness. Actual savings will vary depending on product specifications and dimming level.”

Wouldn’t this be more meaningful as a scatter plot so you could compare cost per watt?

It's designed to look like a Christmas tree to be meaningful to people choosing a smart lighting theme for the Holidays. It's intended to be indicative and immediately understood by the average person scrolling through their social feed.

I just realized you have it set to 1 pound per watt. It may catch someone’s attention scrolling through instagram but it’s meaningless

Good point! The right-hand chart should be percentage of energy rather than watts.

*the Philips Hue press release did not mention Warm White, so I made a guess as it is somewhere in between cool white (4000K) and yellow.

These numbers apply to a specific, specialized light bulb from one manufacturer. The electricity consumption will be low for blue because the light bulb will be very dim overall if you set it to blue. That doesn't mean blue is the cheapest light to produce. Your picture is very misleading.

Thanks for the feedback. As I stated, the source is Philips Lighting/Signify - one of the biggest lighting manufacturers in the world. Their Hue range is hugely popular and many people will be using their lights to decorate their homes for Christmas. I pondered making the title: "Relative energy cost of Philips Hue", but I thought "light colours" was more search-friendly.

How different would the results be for other brands of colour-changing RGB bulbs?

The post should stand on its own, without the source comment. Nowhere in the title or the post is any indication that this is about colour-changing RGB bulbs, or one specific product.

I expect significant differences between products, but that's not even the main problem.

Blue is the cheapest cause it isn't even light. Blue Christmas lights are most confusing thing, how do they look like they're emitting dark
