I am converting my arc lamphouse to metal halide. The lamp spec sheet says- Cooling- forced cooling (fan);min. air flow at bases:1,5m/sec? What measument is that?? I was planing on putting a fan at the top that I have that has 107cfm spec, would that be enough? Should I position another fan at the base of the lamphouse blowing air across the lamp?

The linear speed of the air is what the lamp manufacturer speced 1.t metre per sec the fan is is in volume rate cubic feet per minute

So what would my CFM measurement be for that lamp? Or my L/hr measurment be?

1 cubic meter = 35.3146667 cubic feet.
