So pleased with these bulbs! I have an entrance hall / stairwell / landing without windows which is quite dark. These bulbs have transformed the brightness! I also love the feeling of a sunny day every day! Tempted to change a couple of other rooms to these too!

It's really white. It says it mimics daylight but it looks like I'm in an office. I'm hoping to lesson the impact with the right lampshade

A difficult to find product which was available. The product however although described as daylight colour rendering does not now seem to have the kelvin rating on which it previously did which accordingly lacks detailed information which would be helpful
