Outdoor LED Flood Light

I had a new outdoor LED light with motion sensor installed to light up the side yard if anyone approached the house. It was a great light - very bright and worked very well.
But within the space of a few months it began to dim and become less bright, then I noticed some of the LEDs within it were failing. Now it barely lights up at all.

LEDs are ment to last for years, so I was wondering could it have resulted from some kind of water damage - or leakage from rain??

Any ideas? I'm no electrician.

Hi, LEDís do a nice job, but they do not live up to their expectations often times, remove the lamp and get a replacement, what type of bulb do you have ? Mfg.

Just like compact fluorescent lights the advertized lifespans are highly optimistic and LED's are no different. I think quality has a lot to do with how long a light lasts. A inexpensive light bulb of any type often has a shorter life than a quality (more expensive) one.

Many LED lamps are made using 100s of individual LED. The individual LEDs are connected by printed circuit board traces (printed wire) in some series/parallel fashion based on type of power supply. If a printed wire opens or a individual LED in a series connection fails, the LED lamp light output is reduced. If the power supply fails, there is no light output. Many lamps have an internal power supply so a failed LED lamp can occur with all individual LEDs and printed wire in an operable condition. The consumer still calls it a failed LED.

There's a race to be the cheapest (in a lot of industries, not just light fixtures). Unfortunately, that means using cheaper components with cheaper connections and less expensive manufacturing processes.

Paying a bit more for a new fixture might be a good solution, but it's getting harder to find quality manufacturers.

If it were me, I'd just pick a different brand and install it. Most should last a handful of years without a problem. I'd even consider contacting the manufacturer, they might replace it for free - especially with online reviews being so important these days.
