So, not just dragging this up for no reason, I've been working on the light lately with good progress. So far I have made a cage for the reflector and have it mounted into the cage, I'm currently constructing the mount and focusssing aperatus for the bulb and I've purchased another welder mainly just for this light that will have a 100% duty cycle at the required voltage and current output.
At this point I do have a question, I realize it will be hard to get any exact information as I don't have that much info to go on. The literature for the lamp specifies 6m/s cooling airflow, my reflector has approximately a 3.5" center hole and I'd say the lamp occupies about a 1" diameter area in the center of the hole. With these factors in mind I'm wondering if anyone has an idea of the cfm I'm going to want for cooling this 4kw lamp?
Using a calculator for ducts I'm getting about 70 cfm required for the area of the reflector hole including the subtracted lamp diameter. I'd suspect I'd want more flow than that as the air will imediatly begin to disperse and loose velocity after flowing through the reflector hole? I guess mainly I'm wondering if anyone has specs on the cfm of coolin fans used on lights of similar size?
