cheers, can i ask approximately how far away as i do not have a temperature guage to check? it says 2 inches in some books but i have the lamp about a foot away and the leaves still turn upwards. This must be for CFL lamps. Just an approximate because then i can alter slightly to test to see if the leaves do point upwards or not. Cheers LIP uve helped me out loads of times lol.

Cheers

Bob
