I'm looking at htgsupply.com to buy lights, I want to get 2 1k watt MH lights. and had a few questions, this might be a bit long but if you could bare with me I'd appreciate it a lot.

It says the sunmaster is the best type of lights they offer. They are cheaper than the agro max and offer more lumens

But what worries me about them is they say that thier 1000 watt metal halide bulbs are for both veg and flowering... I don't want my plants to ever flower unless I put them under my HPS lights. Will the sunmax lights put them into auto flower?...

Also the Agro Max has less lumens than the Growbright but claims that they have a better light spectrum, more towards the blue specter... Will that be more benificail than the extra 25k lumes?...

Also the Growbright is a conversion bulb and on sale. Conversion will only output the light you set them too, correct?... And is it just as good for veg as a light designed purely for veg?

Well you have to understand that the blue MH lights are NOT for flowering don't know where ya heard that. HPS is the red spectrum and IS for flowering. Conversion bulbs for a 1000 is 600 HPS and 400 MH all in one bulb. The conversion can be used with both cycles as can the others but usually vegging is not done with HPS although it can and has been done many times. Most 1000s are between 140000 and 147000 lumens either are fine at that point

It says right on the the htgsupply.com website, this light is great for veg and flowering it said something along the lines that it has wide spectrum that includes a lot of orange rays...

The MH 1k watts are usually right around 100,000 lumes is what I'm finding... I think you're thinking HPS, they have more lumes per watt

No, halides go up to 125000 watts for sure. Ya you are right about the wide spectrum that is called a conversion bulb. I may have misunderstood what you meant, they may have called the conversion buld an MH. But bulr/white is for veg. and red is strictly flower, idealy
