DON'T PUT IT IN THERE!!!!!
Only use bulbs that are rated the same as the ballast.
1000watts of light is not a lot of light for a 3'x6' area. It would actually be lit better by 2 600watt lights. I used to run 400watts in a 2'x2' area, and a 600watt in a 2'x3' area.
I am going to be putting a second 600watt light in my 4'x4' space, which is 1200watts in there. Which is more watts than you have, and in a smaller area.
If you can keep the space cool, make it like 3'x4' and that will be perfect for a 1000watt light. The more watts per sq ft, the tighter your buds will be, and the quality will increase dramatically.

Mammal,
That's not very good advise...put a higher watt bulb in a lower watt ballast???...uhhh that sounds dangerous...better re-think that there buddy.

It will be perfect for you. Just make sure you have PLENTY of ventilation. If you don't have the ability to keep the area cool, you would be better off with a lower watt light.
You can get the same yeild from a 400watt light with great conditions that you can get from a 1000watt light in crappy conditions. It is more the environment than it is the lights. To some extent anyway.
I run a 465cfm blower for exhaust. And my 600watt is air cooled with a crappy booster fan. (I'm upgrading that in about 7 weeks, don't buy one those to cool your hood.) My temps right now stay around 4-6 degrees above ambient and the room my stuff is in stays about 4-7 degrees hotter than the rest of the house.
So you have to figure, with a 1000watt light, using this same setup, my temps would probably be more like 8-10 degrees warmer than ambient, and the room would be closer to 7-10 degrees warmer.
With this in mind, to keep you cab below 85degrees, about the max you want to go, you need to keep your room, which is warmer than your house, at like 75degrees at the most. Many times this is difficult in the summer. Especially using central air, which would need to be set near 65 degrees.
Just keep these things in mind when shopping for lights, hoods and fans. Remember that a fan "rated" for a certain size room, is "rated" at that because it can exchange enough air to keep fresh air in the room. It is not saying it can keep that room cool enough to grow in. Spending more money on a quality air cooled hood and a quality, oversized fan will save you a lot of money in the long run, and your plants will thank you.

i didnt advise it, i mearly said it was possible. and certainly a better idea than putting a low wat bulb in a 1000w balast.
