Below the first review, which I now have to revise !! The first of my lights was obviously defective and showed only a fraction of the power that you may have! After a complaint with Philips and I got a new look: bright, is actually brighter than my iris and Bloom. While the battery is still not exchanged, but -and with mains operation it runs most of the time hereby nothing to complain about. And that's why there is now full 5 stars. Thank you for the quick help Philips (was the review on Amazon but what value!);).
Nevertheless, here are the old evaluation with the appropriate comments ....
Had Hue GO performance of iris bulbs, I would immediately buy two. Lt. Data should the lamp with 300 lumens (at 4000 Kelvin) be lighter than for example the sister models (or Iris Bloom). This is not the case defakto. The refusal Philips not to make the battery replaceable, I see it as negative. Thus, there are unfortunately only 3 stars from me, even if the men are in the comments so entirely disagree. Opinions are now subjectively times ...
