Cheap HIDs - Why and why not?

I am helping a buddy setup a grow room. He has been pricing out lights and I've always used Hydrofarm nice lights, but he's a frugal shopper and insists on buying some cheaper ones off eBay. I told him there are definately downsides to cheaper lights but I really couldn't tell him WHAT they ARE since I've never used them. So maybe some of you could shed some light on your cheap light tips/nightmares/opinions with us.
We would prefer advice from ACTUAL EXPERIENCE. No speculation etc.
Is there a 'middle-ground' price/quality light you'd recommend. Lights in question are 400w MH and 1000w HPS.

Make sure he doesn't buy a *used* light, but that goes without saying I hope.

I have always thought Hydrofarm, built good pieces. They will last for many years, and replacement parts, are easy to get. I have bought the cheap replacement lights, at places that sell general lighting, and I,d say, its better to stick, with the name brand. IMO

a chinese set up i bought a while back would make a lot of noise. the light would flicker off in middle of the light cycle after only a few months (bulb was used later with different, hydrofarm balast, and no problem, so im assuming it was the balast). i got rid of it fast. but hey, the color was cool, it came in blue

Do not buy any equipment off ebay if its going to be used for anything illegal. Ebay is the biggest bunch of informers you ever want to see. Cops don't need any warrant or court order, ebay will turn over all info just for the asking. To save money buy a ballast set and reflector separately. Shop around using google and froogle and you'll find loads of deals.

your friend may want to look into industrial surplus places in his area.
while not conventional, and maybe not for the novice,they usually have a plethora of HID lighting, that while in used condition, can be had for exceptional deals.

Usually the biggest difference between cheap and pricey bulbs is the spectrum. Hydrofarm, Hortilux and some other have a spectrum made to grow plants most of the other cheap bulbs are the type used in shops ans warehouses. They will give stretchy growth even though the light is bright because it isn't as usable to the plant.

I knew about the bulbs but what about the light ballast itself with a good bulb? What problems have people run into doing that?

With cheap ballast they often don't fully power the bulb to it's fullest. You have a good ballast next to a cheap one and have the exact same bulbs but when one the color of the light is a little different between them and one will read different on the light meter. Right now the best ballast out are the electronic ones.

The digital ones are pleged with malfunctions at the moment, so I wouldnt call them superior yet. And im my experiance expencive bulbs arnt worth th extra cash, I go with a Sylvania or Philips(Philips is prefered). Some floros would help alot more imo. Id sudjest T5s but they are also in early development, few more years and everyone will be using Digital HPS with ceramic halides and LED supplementing all around the plant.

They got past most of the problems with digitalis some time ago but yeah they were really bad for a while. Your talking back when they couldn't even figure out how to make a digital 1000 watt. They even have longer lifespan ratings now and 3 to 5 year warranties. Now the bulbs I've seen used here and there since 85 and can pretty safely say that a good sunmaster or hortilux with a good light spectrum is gonna do way better then the cheap bulbs. they put out more usable light to the plant so your gonna get way less stretch between the nodes esp if your talking a strain like a haze or some pheno's of blueberry.

You may wanna re read that cause every book he has every dvd he's made and so on says to use HID lights. He's pretty easy to get a hold of.

IMO you get exactly what you pay for when it comes to specialty lighting. I've used cheap bulbs in the past and they've always had the same problems: low output, wildly varying spectral shifts, and shoddy build quality/life expectancy. In reference to the 400W MH, I'd recommend an Iwasaki bulb. High output, affordable(~$60), very little spectral shift and will last for 3 - 5 years.(My experience). In reference to HPS, you can't go wrong w/ Philips or EYE Hortilux.
As has been previously mentioned, tell your friend to stay away from eGay and start looking at some of the many respected dealers online. He/She may end up buying components from different sources and still save some cash. HTH
