3 reasons why your LED strip lifetime claim can be inaccurate

The LM80 take a look at and corresponding TM-21 methodology have a number of ailments and prerequisites for life span claims. If your LED strip provider did not abide by these guidelines, their life time statements may very well be problematic.hong kong university master

1) It's possible you'll only claim as much as 6x the number of hrs that was really examined. Basically, when the LM80 examination period was only five,000 hours, although the LEDs performed flawlessly, the longest lifetime you may declare from this facts is thirty,000 hours. This is to make sure that premature conclusions aren't drawn dependent on minimal information.

2) The generate existing and situation temperature parameters to the LM80 tests should be bigger than the push present and situation temperatures made use of over the LED strip. As described previously mentioned, temperature and push existing would be the main variables that impact LED longevity. If the LED strip is configured to operate at a better push present and is particularly routinely used in a incredibly hot attic, your true use situations may well exceed that with the LM80 checks. Because of this, the original lifetime predictions might be an over-estimate.

strip lights and light ribbons offered by Brilliant Lighting are low in power consumption yet high intensity, making them perfect for decorative use including amusement parks, theatres, cars and others.

3) LM80 and TM-21 isn't a perfect, foolproof lifetime ensure. Other components which can be not incorporated from the take a look at methodology, these types of as humidity or VOCs identified in potting compound for water-proof LED strips could also have an impact on LED life span. In addition there are few policies on what components is usually substituted within an LED's construction even though making use of a similar LM80 examination report, so a manufacturer aiming to minimize corners may use superior materials to the samples used in LM80 tests only, and for mass generation use inferior, less costly products.
