Got this LED RGB bulb from banggood http://www.banggood.com/E27-9W-IR-Remote-Control-16-Color-Change-RGB-LED-Ball-Bulbs-85-256V-p-83013.html
labeled as 9W, to replace a 15W fluorescent warm white bulb. At 9W I expected this light to at least come close to the fluorescent, but it fell far short of that.
RGB bulb set on white (highest brightness stage too of course).
Old 15 fluorescent bulb.
Both taken at ISO 100, 1/10 sec exposure.
The LED bulb reaches maybe 20% of the old bulb’s brightness, and that’s a high guess. It’s too dark to read a book if I sat directly under it 
So, is this to be expected with this kind of bulb, is the wattage here similar to the exaggerated lumen claims of some lights; or should I ask for a refund?
On the plus side the remote came already loaded with a CR2025.
