We bought these to replace the standard bulbs in our Cosmos cooker hood. The lights supplied were star white (should have been 6000k), very eye-obstructing and only focused on the rear burners, and the sockets didn't allow for light adjustment where it was focused. Still bright white but more neutral than star shaped, these new 4000k bulbs are easy on the eye and have a wider spread that illuminates our entire hob plus a bit of worktop either side, which is exactly what we wanted. Very happy with it!
