how do you know when its time to get a new light bulb? (for 600 watt) do the bulbs burn out or does the quality noticeably diminish? Thanks!!!

6 months replacement is the general rule but many growers run them for a year or more . Simply looking at a bulb will not always tell its burn time and lumen loss , hence the use of light meters or a simple schedule for replacement . Although many growers push the thresh of a yearly replacement it is up to you , some people are happy and content with bulbs that are several years old .

thanks!! can you guess when its time to replace the bulb with the way light affects the plants? ie. more sparse growth or over all less growth? or is a year a rule of (green) thumb?

You'll need a light meter to know for sure, if your worried about output buy one at a home depot or so. It will be cheaper in the long run rather then guessing. And no you won't be able to tell by eye.
