What light cycle does the globe run eg how long at 18/6 and how long at 12/12 ?

Im on my 3rd grow normally first 2-3 weeks 18/6 8-9 weeks 12/12 ..
Most times about 6 months you should replace the bulb. That is if I remember right but I am tired and going to be a lazy arse and not checking to make sure. lol

Ok it sounds like your probably due for a change. I was recomended to change bulbs every 2 grows.. I cant provide proof but am pretty sure Ive seen threads on here stating how many hours till they lose efficiency enough to warrant replacement. I keep 2 the 2 grow rule as a long time ago I used my first globe for 2 years and being a stoner didnt even think that that was the reason why I didnt produce anywhere near what I used to.

is it a bad thing to put up so many pics and say how well there doing up .
HPS lamps last a long time...
Here are some typical lumen maintenance figures (Osram NAV-T SUPER 4Y 400 Watt):
2,000 hours 98%
4,000 hours 97%
6,000 hours 96%
8,000 hours 95%
12,000 hours 94%
16,000 hours 94%
20,000 hours 94%
And here's a table to convert those hours into something a bit more useful:
