Ikea TRADFRI bulb E27 CWS opal 600lm gamut

Ikea TRADFRI bulb E27 CWS opal 600lm gamut

These measurements were done with a colorimeter, not a spectrophotometer, so they're not a 100% correct but still a lot better than nothing.

Each measurement was done 10 times, then averaged.

The bulbs do pretty well with red, really well on blue and quite terrible on green staying very much on the yellow side.
