LED shop lights

55 50 Ron · Aug 19, 2017

Has anyone had trouble with these lights? I bought three in Feb. of 2017. One has failed. I didn't bother to ask if it was warranted. Probably 90 days if any warranty. I just took it apart to see if it could be fixed. There are 155 LEDs in the 4 ft length and only from # 1 to # 80 come on. I measured across # 81 using the diode position on my Fluke 73 multimeter. It showed open. I removed that diode, but from 82 to 155 still don't work. I doubt they are all tied in series, but it is impossible to tell from the back side of the strip. Voltage at the end of the strip is 55 VDC and not sure if that is correct. Of course these lights come with no manufacturer name or specs so it's just "hunt and peck" to try to do a repair. Also they are so fragile that the diode that I think was bad was totally demolished in removing it using my very small solder iron. Most likely a flow-solder job to place them originally and never intended to be repaired. So I just trashed most of it. Kept the main LED board and the power unit out of curiosity. Think I'll look for a fix on You Tube and even though it's too late to fix this one, I'd still like to know some details and specs.

You have to have around 2&1/2 volts to check LEDs. One way to check is to measure the voltage drop on each led.

We've been using LED's for a while, you pretty much get what you pay for.
The cheap no name bulb's didn't last long and had poor light quality, we bought higher priced name brand bulbs and haven't had any issues since.

Always keep the receipts for those things .Don't try to fix it ,return and get the money back.

I've had similar failures with LED lights. I've also experienced a few of them that turn into strobe lights. Sorry guys, I've bought my last LED light. I'm sticking with incandescents.

I got tired of changing out incandescent bulbs all of the time, we have three poultry barns with 52 light bulbs inside each barn, these lights are on over 600 hours per month.
I was buying incandescent bulbs by the case and would go through over 3 case of bulbs per year.
We tried the curly florescent bulbs but the light quality was bad and they flickered a lot, plus 6-9 months was all they would last.
Switched to name brand 4000k LED's last year, instant on, light quality is very good, don't dim down in cooler temps, only one bulb has gone bad so far.
Also swapped out 2 sets of 4 ft florescent lights last year with 4000k LED's in the shop, I'll be swapping out the rest as the florescent bulbs go bad.

As I said before, cheap LED's are usually junk and will turn one against them, once you've used good LED's you won't go back to anything else.

Forgot to mention LED's lowered the utility bill for the poultry barns over $200 per month over incandescents.

So what is a good brand? And where do I buy them? I've owned several different brands, purchased at different stores, and I get the same results. Some are good, some are NOT good. LED bulbs to replace the incandescents come 4 to a pack. The last pack of 4 I bought, 3 were good and still working, the other one worked good for 1 day, and then became a strobe light. The 4 pack before that one worked good for 1 day, and then 2 died completely. Incandescents burn out also, but don't cost nearly as much.

Last screw in type we got where Phillips, don't remember the name of the 4 footers, got them at a electrical supply company, $18 each but worth it.
K rating on LED's is important, 2800K is like a soft white incandescent giving off a yellowish light, 4000K is as bright as I'd want in a house and looks more like natural light.

Don't get the idea that you are hurting anyone's feelings Rusty.
