Stopping light leaks from PC fans

Hey Cab growers,

Quick question, I've just made a small cab and have 4 PC fans providing the air flow, 2 intake and 2 exhaust. My question is, does anyone have any tricks to stopping the light coming out, or in for that matter from the fans? Im thinking of just using some 150mm ducting over them and screw it to the wood but i dont want to reduce the air flow too much...

any tips would be much appreciated!


cheers
Mo

here is my idea for this problem...

I made one out of foam board. It extends out a bit and it has two pieces of board in thr.middle.


Think of a maze. It seems to do the trick. If u want a pic or tut lemme know and ill post the link

Cheers dude, is there a particular post that you are referring to? Pretty ingenious little grow box there

edit- just saw the behind shot. Does that still let light out though? +rep for the wicked cab man!!

Sounds good also, not quite understanding it properly though, a link would be fantastic thanks mate

Put a 90 deg. elbow on it, light only travels in a strait line.

Ahhh yes that would work!! Cheers dude, got some of them lying around too

same idea, but different material, make the elbow out of aluminum foil
very easy to work with

Cheers mate

Here is the link i used.

It works pretty dam good. I even went one step further and put a panty ho style sock over the exit to act as a filter for other things coming in and out.

and if smell becomes an issue i am going to put carbon so the air has to go through the trap

Sweet man cheers for the link, I'll have to see where I can find some of that foam but it looks like it will work well

Cardboard should work but th foam stuff was about 4 bucks at walmart

Oh ok cool, will scout around hey, cheers for the suggestion dude

i used two 90 degree bits of elbow for mine and its working very well. just sprayed the inside with some matte black paint and i was done. you could make a box and then have something like this. but smaller and more suited to your lights of course

Lol, some people are gettn all fancy. I just cut 2 holes in the lightbulb box I got (at a 90 degree of course) and then taped in onto my pc haha
