Lighthouse Hydro is doing it wrong.
Does anyone else think the blackstar units should pull air in through the sides of the panel and out the top, because I do. Outtakes are usually located at the top of our tents. It would be nice for the heat to be in that direction vs ambient heat out the sides.
A majority of LEDs will have the fans blowing in from the top at the heat sink then out of the sides, because that is how the heat sink stays cool enough to dissipate the heat from the LEDs.
A fan can't really suck heat off of a heat sink, but it can blow cool air onto it and cool it that way.
I honestly don't think it will make that big a difference. The fans on my bs500 are so close to the led panel that whether the fans suck or blow, air will move past it rapidly. But hey... I haven't tested this theory so maybe I'm wrong.
You could test it on your Blackstar and tell us how it works out. Take your Blackstar apart, flip the fans over, and put the panel back together.
If the fan would be sucking from the sides it would be sucking in more moisture than with the intake up top. If your fan is sacking out the top of the room like it should be then the hot air will sucked up to it anyways.
Show me something duct tape cant do.
Yes you are correct when drawing heat from a heatsink/condenser/heat exchanger/etc it's always better to draw out the heat instead of pushing it through....heat rises(duh) so it makes it counterproductive to draw the air from the top of the panel
Edit: check any modern electronic equipment(computer/dvr/game console/amp/blah blah) and see that the heat is being drawn out(by the fans) off the units........

That is true, but those weren't designed to be used in an environment where water is sprayed around often and moisture buildup is common.

Air conditioners, refrigerators..(water is a by product of these)..etc......still same design......
I don't wanna argue and jack this thread, but while that is true, I bet your grow room is more humid than your house, and air conditioners don't spray the waste water (that was removed from the ambient air) back into the air. I also don't think that a refrigerator's compressor sprays water in the air regularly, nor do I put my electronics behind the fridge when they are running to keep them out of the way.Air conditioners, refrigerators..(water is a by product of these)..etc......still same design......
Edit:
I was just trying to explain the reasoning behind that design, there is a reason for it
Yes the unit will not cease to function if it sucks up some water, but sucking up water every couple days for a year will cause some extra wear.
