Quoted from Lermods:

What’s your bracket made of? Metal? Maybe strip is shorting against the bracket somewhere? Break out your meter and find the wire causing the short. Put the strip back in the bracket, power off and test for continuity across the different solder points. Your pics aren’t great for diagnosing, but maybe when the strip is being moved, it’s shorting where your solder joints are.

Quoted from DugFreez:

Let's see about shutting this down right now. LED light strips, if not tampered with and sanded on...do NOT conduct electricity on the back of them. None that I have ever bought do anyway. Maybe the low budget ones have an issue with that, but I've never seen it. The material of choice for LED light strips to be stuck to is metal (usually aluminum) light channels. This is not only safe...it is preferred as the metal works as a heat sink. Dispersing the small amount of heat they do put off and extending the life of the LED light strips.
I'm a bit touchy here as I have had "competitors" lie to try to ruin my businesses by making up tales about metal being a bad idea and dangerous with the LED light strips. Of course they also tried to trademark the name "Speaker Light Kits" years after I designed the product and had my website opened. That just shows what a class act those guys are. 1000s of my Speaker Light Kits have been sold since 2012 with the vast majority of them using metal frames. Besides a few stray shorts early on from the cut off connection areas of the strips coming in contact with the metal frames and blowing a couple of fuses.....it's been a non-issue. Now those connection ends are protected and checked.
Also....the metal frames I use on my SPIKE 2 Speaker Light Kits (which are being used here) are coated steel (not aluminum) and do not have any continuity to them unless you go digging a probe in them or scraping the edges or holes of the frames looking for a connection. The bare metal spot you are seeing in the picture is not a bare metal spot and I was wondering what it was myself. It looks like he may have stuck a piece of tape there or something. Now that I look at it....I'm pretty sure he put some tape there so he could make a visible mark to designate the bottom middle of the frame.
Sorry to be defensive about this, but I'm not looking forward to the "It's dangerous to stick LED light strips to metal " lie to recirculate again. Do a google search for "LED light strip channel" and you will see most of them are made of metal.

Yes, it was directed at you...that is why I quoted you. You are the one that said:

and that is what I was wanting to respond to....so I did.
Don't misunderstand and think I was referring to you when I mentioned "my competition" that were telling people that using the metal frames were bad with the LED strip lights. They were doing that with intent to slander and sway people away from my product and toward their shoddy knock offs. I didn't think you had any ill intent with what you said...I just wanted to put a quick stop to it, as it's false. As I said, a google search will easily show the safety and advantages that using a metal backing for LED light strips has.
So no beef assumed from you and no beef intended with you. I just wanted to get the facts out there before any disinformation could take hold.

Quoted from DugFreez:

Well sorry about that...I was trying to address what you said about "worth noting to avoid ever putting a strip on metal", as nearly my entire business is putting and selling strips on metal.
I would hazard to guess if someone made a claim about how using 3D printed goods in a game should not be done and people should make note of that....you might speak up. That's pretty much where I stand on this. You mistakenly made a statement that could clearly hurt my business. One that others have said in the past for the sole purpose of hurting my business. So I wanted to clarify that what you said was incorrect.
I didn't think you were saying it with ill intent and I didn't mean to come off as accusatory. I just didn't want that, potentially business hurting statement, out there...without clarifying it and pointing out that using the LED light strip on metal is not a bad idea or an issue.
