Thanks for the compliments and for the tips!, i won't try 250w bulb with this system.
Now the temp' is 15-17 C at night and day time it is not reaching above 25C
I guess here in Israel it is not a real winter outside 6-7 C at night and 22-28 C day time.
maybe in the Israeli summer time i will have more difficulty to steady the lower temp' with the lights on. it can reach outside to 40C .
