Poor quality bulbs regarding safety issues, NO safety or identification markings on bulbs to say what they are and the internal 240v electronics were very easy to get to by way of a loose glass screw cap, returned by advise from electrician who said they were very cheap and not safe. Customer service when returning the bulbs was terrible, spoke to 3 members of staff across both sales and returns and still took for myself to phone up and chase the return. I was ignored by staff, return took over 3 times longer than it should have (17 working days) and it would have been longer if i left them to to it. I would have given the rating as VERY POOR if it wasn't for the fact the first delivery came on time, i would never use this website again.
