Is one 6" fan enough for 3x 600w light bulbs in cool tubes?

That fan is rated at 550 m3/h
That is a little weak... but if you are bringing in real cold air than it should work alright
I use a 306 CFM inline fan for my 400 watt cool tubed HPS and temps get a little high sometimes when it gets warmer outside

I think I'm going to try two different ways and see how it pans out.

1. Use the 6" fan to suck air from outside, through the 3 lights and exit. Then use the 4" fan for the tent.
2. Use 6" fan for 2 lights and the 4" for 1 light.

Thanks to all that responded.

call me lucky but I run like this. 6" dia. Carbon filter up high......4" can fan... the green generic one.....insulated (pricey) 4" ducting through 3 600w either MH of HPS in a straight line....these are sealed 6" hoods with reducers....more 4" ducting....out through 4" flange in blacked out door......It's nice and cool.......OH wait i'm an idiot........I have a portable air conditioner I got for 50 bucks on craigslist.......Get an air conditioner......I vent it through that pricey 4" ducting also.......I found the ducting for the big box stores makes a fk load of noise like a flute...........$19 bucks for 25 feet a the good stuff and its dead quiet on the exit side.....my room is mostly sealed and i get frest air from the house...That comes in through carbon filter from HVAC section at the big box stores.....1 other thing my hoods had tiny leaks on two sides where the glass dipped a little as its only supported on two side....tape that area up as on the third light it was like a little blowdryer of hot air......
