Hi,
Thank you so much for your reply and advice.
I currently have 8w bulbs in but I can only find the higher wattage ones at 10w and was concerned they may do damage.
Thanks for your advice re the LED bulbs. And for explaining about making sure they're the correct way round. I must be looking at manufacturers who aren't making great products as there's so many negative reviews on Amazon for them. Please may I ask you what brand and wattage LED bulbs you use so I can try to purchase some.
Many thanks again,
Alexis.
