Sadly out of the six I ordered only 5 actually worked.
I bought these bulbs for a daylight effect in my living room. I needed six bulbs but sadly only five worked. There was no option to change just one faulty bulb of a replacement, which meant returning the whole order. In the end I decided to accept the order with the faulty bulb and it now looks like I will need to order three more even though I only need the one.
