Three 400w HPS lights for $100?

i just saw an ad for one HPS light for $50 dollars a few days ago so i responded

i didn't write back after the initial reply and now the guy is saying i can have three 400w HPS lights for $100

it says that they have been used in a warehouse for a few years

they look like this

Well they are what they are but dont believe that they have only been used for a few years,count on heavy useage for many years,i'd buy them as long as i could see them cycle on & off several times & make sure there is no problems.

Then i'd take them home & clean the hell out of the interior of the ballasts,dirt & dust build up is the worst enemy of electronics that produce heat,for that price i think its a no brainer as long as they cycle on & off properly with no ignition problems.

yeah he said he would cycle them on and off

even if the bulbs have some hours on them i can always get new ones from my local hydro shop
