<div>It should power a LOT of LED's. How
many were you using and what sort of current limiting resistor did
you have....a quick circuit diagram would tell a lot.<br>

<div>A little question about AC adapters. </div>
<div><br>
</div>
<div>I have an artwork that I did that I used an AC adapter to
get power. It was on for 4 days during a show, and I was
surprised on how hot it got. (I almost burned myself). I did
have duct tape on it holding it to the back of a wall, so that
may have been half the problem.</div>
<div><br>
</div>
<div>I'm showing the work again, but I'm wanting to make sure
everything is safe. I need to hide the adapter due to
aesthetic reasons, so I wanted to create a little white box
around it with air holes, and I was suggested a fan, although
it if it getting hot due to over working, adding another fan
might not be a good idea. </div>
<div><br>
</div>
<div>It is only a bunch of IR leds that it is powering, so I'm
surprised at the power I am needing. </div>
<div><br>
</div>
<div>any help would be very well appreciated. </div>
