hey guys i was going through a hardware store today and i saw some halogen floodlight that i thought would be great for flowering , they are 500watt halogen floodlights only 18 bucks i was like wow i dont believe lol, i was thinking of have 2 making a total of 1000watts for 2 white widow plants, at the moment im using six 52 watt daytime 5 foot flurocents they are ok but its time to upgrade and these i think can work really well, they use less space and produce the red spectrum aswell, i aslo just bought a 400 watt hps today but think the halogens would work better as they will be more poweful then the single hps but just need to know what you guys think as you guys have more experience in all this any help would be great cheers guys

Hi high'...Halogens aren't satisfactory growing lights. They produce a lot of heat and do not have a spectrum beneficial to photosynthesis.
HPS at 50 watts per sq. ft., is your best choice for a single light setup.

50watts per square foot is what everyone recommends for HPS lights

im not sure about the watts you will need specifically

Your space in U.S. is approx. 6' x 3' x 7' tall.
6' x 3' = 18 sq/ft. That comes to 900 watts HPS neded to light up the entire growspace.
Two 400-watt HPS would do it esp. if you upgraded to full-spectrum bulbs, or a 400 watt & 600 watt or a single 1k watt.
Those put out a lot of heat so you'll need ventilation.
BUT first I suggest reading a growbook or 2, to get at least a basic grasp on what you're trying to do.
