Blowing Out LEDs

I have some LED lights burning out. They were installed by an electrician about 2years ago and are hardly used. Basement reck room.

Reading the package we are looking at 30,000hrs, break that down I could leave the lights on for about 3 years no problem.

Thanks for any assistance.

Most compact fluorescent lights also have the same problem of life nowhere near the claims. In your case if you read carefully they advertise 30'000 hour average life per LED. They don't say the fixture/system will last that long. They just say that that one component (the LED emitter) has a very long life. There are a lot of other components that go into an LED system so you multiply all their failure rates and you end up with a fixture have a much shorter life span. Generally all it takes is one component to fail and the entire puck or light does not work. Also, the LED is the last component in the system and all the other components upstream bear the brunt of voltage spikes protecting the actual LED emitter.

This is one situation where buying quality can really help. Inexpensive lights are made from inexpensive components and tend to have shorter lives.

Pilot Dane is correct. I tell my customers that no light will last as advertised. However, if you were to leave a light on and never turn it off, you may very well get the advertised life or more out it. The light itself is not to blame but in conjunction with what Pilot Dane says, turning a light on and off is the single biggest "killer" of bulb longevity. Think about how you're using it. If you go into a room on a regular basis, its better to leave the light on the first time you enter the room and leave it on until you retire for the night. Also certain bulbs like CFL's are not good for areas that require quick and bright light for only a few minutes (like going into the basement to get some canned goods). Then turning the light off when you come up. CFL's recommend that you leave them on for at least 20 minutes to get full light and capacity from them. On the other hand a four foot florescent light fixture for the washing machine and dryer is ideal when doing a weekly wash. Turn it on when you start and leave it on until you're done. They are also very good for work bench purposes. LED's will light bright immediately and give good light for as long as you need it. Those can usually take a bit more of a on-off cycle. But as mentioned by PD other components might not. Here is a case where cost is probably reflective of quality.

Also keep in mind that wattage is no longer the mark you use choose a light bulb. Lumen's are what you should be looking for along with color (kelvin temp). (2700 K is suppose to be equivalent to what the traditional incandescent light that we are all so use to.)
