How do you decide when a bulb needs changing?.......hell I prefer cheap hps n mh bulbs from lowes too over most the hyped grow shit I just change um more often cuz they cost about a 1/3rd ....
Basically after time past is what I do, you can attempt to go another round with them but sometimes you yield less and wish you had new bulbs. It really differs from person to person and what your end goals are but I change bulbs after 9-12 months roughly.How do you decide when a bulb needs changing?
I have a cheep light meter, but getting good data out of it is a problem.
Can visual inspection of the bulb inform a replacement time?

shit i agree w you, ive damn near made a living on craigslist, buying iphones for 200 selling on ebay for 375, all day.I am not gonna hate on craigslist- I got most of my op through there! I hear people's concerns about safety and whether the gear is good, but I have yet to be burned. Maybe I'm just lucky...
those double enders come in 600w?A light meter won't help you, which is counterintuitive as hell, huh? What happens in older bulbs is that resistance builds to the arc passing through the tube, forcing the bulb to pull more voltage. The efficiency drop is more from this voltage rise, and less from any direct reduction in lumen output. Don't get me wrong, lumens DO drop- just not fast anough to fully account for the efficiency loss.
If you want an HID bulb that doesn't have this problem, check out Gavita's new Proline 1000DE setups, with the Phillips double ended bulbs. Those fuckers go three full years and their lumen loss is guaranteed to be 5% or less over the full period. In fact, they limit the 'useful life' to three years, only because that's when the bulbs hit their 5% failure rate. Terrible...
Im pretty sure that gavita does make a 600 de bulb and ballast also tty.no, they don't. 1000w only

My apologies,you are both correct and im wrong,The 600 i was looking at is an SE bulb not a DE,since they looked EXACTLY the same i just assumed the 600 was a DE also,live and learn,lol.
