So waiting for my new bulbs to get here.. (Other half just gone to pick them up?. I currently have three thermometers in the hot end. I out an extra one in yesterday as suggested and ready came through as 31.1 cwhile previous thermo then reading 27c which hasn't budged. I've now put a third in there briefly while I wait and it's reading 28c. The third thermo is an eco terra one while other two are slightly cheaper ones.
When tested on it's own it seemed to kick out a bit of heat as I couldn't test other than to just take it out and plug all into mains.
Bulb issue? We will see shortly
