We got a 6 inch cookie tin, tried 40 watt bulbs and it literally burned my hands when I had it plugged in in the house to see how it worked. Same with the 8 inch. So I got the 25 watt flame shaped bulb and it wasn't as hot but was still too hot in my opinion to be safe. Trying this out before we really have to use something. What are we doing wrong? The bulbs are clear, the attachment is two lamp kits. Anyone have an opinion?
