Hi I am having trouble taking the lid of the lamp to change the bulbs. I have seen the video numerous times and still clueless. This is the first time I have tried it so maybe it's got stuck. I don't want to try it again as knowing me I will break it and fork out for a new lamp. Any other ideas . By the way either you need to be built like a body builder or it's quite tough to take off but it can't be that hard to take off surely ?
