LED Myths about Yield, Cost & ROI, Power Consumption, Heat, Life-Span, Warranties
LED Myth #5— LifeSpan:
"LED manufacturer current claims about LED life expectancy disguise real LED product failure mechanisms and mislead customers."
-based products hold the potential to achieve lifetimes that meet and even exceed their traditional counterparts such as HID
fixtures. But manufacturers claims are often misconstrued by users who do not fully understand LED
product failure mechanisms, nor see the difference between lifetime and reliability.
As we noted in last weeks post LED myth number 4
, operating temperature is a major factor in the life span of an LED lamp
lumen (light output) depreciates at a much lower rate than other light sources. Where an incandescent light depreciates within the first 6
s, an LED
will reach the same level in 15
to 20 years
. So when you as a grower use the Best LED grow lights
, you will have the chance to grow crops for years without having to replace your lighting system
lights have an expected lifespan
rated at somewhere between 50,000
and 100,000 hours of use
. In comparison, many other grow lights tend to last for around 20,000 hours before needing to be replaced. Besides decreasing long-term replacements costs, there are also money to be saved in lowered maintenance cost.
A 2013 report from the U.S.
Dept. of Energy titled “LED Lifetime and Reliability
”As with many performance attributes, LEDs have the potential to best other technologies in terms of longevity, but choosing the right product requires some understanding of expected failure mechanisms, lifetime, reliability and serviceability, as well as asking the right application-specific questions.”
We said it before at the beginning of our LED myth Series
that All LED
s are NOT
alike, so buyer beware.
