i think mine was either 7 or 4 it didnt do the job tho it was good for night time warmth as it didnt get very hot. But i wouldnt use one for a a reptile that requires a high temp.
Yeh they aren't much good for Sydney winter. Will usually do the job in the warmer months however. I go for around 30 watts with a larger surface area so you can fit more then one click clack on it if need be. Hope this helps.
The microclimate 7W don't get very hot at all I have found but the 7W heatmats (can't remember the brand) I got from Slothhead (Wehaveitall) are great. They make a 30deg hot end no worries.
thanks guys (and girl)..I just wanted to see if anyone had any problems with them or anything. It's to be in a small fish tank (housing gecko's) and my room stays really warm (lucky me) and I've checked and doubled checked temps inside the tank and they're about 16* and on H.T. they were saying they add around 10* to the temp...but I'll see how it goes!
Anyone else who wants to contribute go for it
