wyteberrywidow you can get digital ballast for 120-180 from anybody...inside sun yeah sells refurbished stuff but warrantied been around long enuff for my warranty.you can get your own reflector get a cooltube for 69 dollars when buyin the light from them.my set up has been trouble free no worries with a refurbed ballast and no buzzing so your point exactly?????
My point ???? Your answer is a little hard to read but I'll give it a try.
My point is I'd rather have a digital ballast that is new and works from the start, since it burns less electric, runs cooler and the bulbs burn brighter.
That is alot better than some inefficient refurbished high bay light that has already had problems to begin with. How cool is a 3 year warranty when it's the weekend and your lights just quit working, let alone the shipping on a high bay light can't be cheap to return it.
All high bay lights buzz sooner or later, usually sooner, and if he's growing that is all the guy needs is people asking where that buzzing is coming from.
The other thing you missed is the HIDHUT kit does come with everything you need, the reflector and all.
I guess my point is, I think the HIDHUT kit is a better deal even if it costs a little more, you'll get the diffference back in the electricity you save in the first year.
