I thought it was over

I thought that after retiring I wouldn't have to smell burned up electrical parts anymore. Last year I wanted to add LED lights to my FW but also had a ton of other stuff to do. I didn't want to make a research project out of it and I noticed LED's in CW and figured they would have good quality stuff so I paid the price and bought about 10 of them.

This year I wanted to put one in the stove top vent and 2 outside and bought them off ebay. I turned on a few lights to check the draw with my Bogart 2030 and after a few minutes I noticed the burning electrical smell. I shut them off and found the one in the stove top was smoking. I removed it with a rag and it fell apart.

I contacted the Ebay seller and since they are lost they cant answer simple questions about it. I asked for a refund and they said sure but I have to give 4 stars positive review. Sure thing goofball, I'll give a positive review so someone else may possibly start a fire with your garbage. Like an RV hasn't got enough issues already.

They had also told me to reverse the polarity. I had bought 2 of them so I hooked the other one up outside to see what would happen. It lit when connected so I reversed the leads and it didn't work at all. ok so now we know that it will only work one way. I reversed the leads again and it lit up. After about 5 minutes it started to smoke so I shot it with my temp gun and it registered 318 degrees and a few of the led's were flickering. At one point I believe I saw 389 degrees flash on the screen. This was at 12.52 volts

Maybe CW price wasn't so bad. I haven't been nervous about the ones from CW but I would be about this junk. The other 2 bulbs in the outdoor work lights dont seem too hot. They are from a different seller. Dang, that price of 2 for $8.00 with free shipping WAS too good to be true. :)

  • Personally I only buy regulated LEDs. Yes they are pricier but not too bad if you shop around and buy a lot at once. Mine are rated to work from 8v to 24v,

    I would stay away from any that mention needing to change polarity in order to work.

  • Led's operate the opposite of normal electronics. The higher the voltage the more current they draw. The cheap LED's won't take much over 12v. When your inverter is on you are probably feeding them well over 13 volts. When I converted my coach I installed a dropping resistor on each fixture. You can of course just buy the more expensive LED's that will accept a wide range of voltages. And yes you were correct in the wiring LED's are polarity sensitive and will only operate one way so that was not your problem. Most of the more expensive LED's are not even polarity sensitive. In this case you get what you are willing to pay for.

    I'm not a EE, but I've read that their lacking a resistor (I think) that other quality boards would have. Since these are coming from China, I would think Quality Control is suspect as well as they could be line rejects.
  • I understand the product was bad but is that the sellers fault?
    The analogy is when a product from CW turns out to be defective do you blame CW or the manufacturer? The answer is the manufacturer. Of course you return it to the seller and he handles it for you as a courtesy but your beef is with the manufacturer.

    I think your blame misplaced. Seller deserves a rating based on the sellers performance not the performance of the product you bought. That is why the seller wants a great review from you first so you do not bash the seller unnecessarily and inappropriately.
  • I've bought only the eBay LED bulbs because I wasn't sure what I wanted or of their light output/intensity. eBay LEDs can be a cheap way to try things out, see if we like them.

    I had one batch of 6 that had about a 50% failure rate. Of the other batches, I have 10 or so in the RV, they're doing fine after 5 months of light (pun intended) use.

    I do think we get what we pay for. I've had color variation and quality issues. But my outlay was also about 1/10th of what it would have been at CW.

    Now, I think I know what I want.
    So when these cheapies die, I'll invest in some quality ones.

  • Hopefully TucsonJim will chime in. He seems to be the go to guy on the board for LED info. He's been there, done that. I saved his profile just in case.
