You're good for about a year. At which point HPS is around 80% lumen output. MH, you'd be down to about 70%. MV, even less(only bulb here with both *usable life*, and rated life expectancy before failure).
After 1 grow(under 6 months) it's likely still pushing out over 90% of the 'brand new'/peak lumens. No reason to change it so often.

no you can't. but you can run a 600wtt bulb in a 1000wtt ballast.

Like i said if you want optimum conditions and optimum results change it every grow. After 1 grow its gonna be less effective. 90 percent efficient is not what i looking for. What is the light gonna be like after your second grow. We are taking over from mother nature when we grow weed, so surely it is our job to provide the best conditions possible? The suns efficiency dont drop with each grow, so why should the lighting we use be any different? Second hand bulbs anyone? Only used for one grow!

It's also going to be less effective immediately upon igniting it for the first time, and every time thereafter. Where's the air-wank emoticon?

I'm surprised you're not an LED grower, as they have, by far, the best lumen maintenance of any bulb.
This guy must own stock in some bulb manufacturer or something.

no mate no stocks in any lighting company just want the best for my plants. I wish i did have stocks the amount of bulbs i go through. What is the point in slagging somebody off when it is totally unfounded? Opinions are opinions. And no mate i am an incredibly successful grower thank you very much.

if they tell you so then go with it, but i dont recomend doing that .i say change it every 6-8 months so that you can get a couple grows out of it . and thats if you 18/6 or 24/0 them other wise you can stretch a year out of them . and of course the shop is going to tell you that so you can keep on spending because they are expensive
