Example of Failure Rate Calculation:
Assume a device operating 8 hours/day, 5 days a week. The utilization factor, given 168 hours/week is:
(8 hours/day) x (5 days/week)
÷
(168 hours/week)
=
0.25
The point failure rate per year (8760 hours) at 25
°
C ambient temperature is:
(0.027%/1K hours) x 0.25 x (8760 hours/year) = 0.059% per year
Similarly, 90% confidence level failure rate per year at 25
°
C:
(0.104%/1K hours) x 0.25 x (8760 hours/year) = 0.228% per year

Notes:
1. The point typical MTBF (which represents 60% confidence level) is the total device hours divided by the number of
failures. In the case of zero failures, one failure is assumed for this calculation.
2. The 90% confidence MTBF represents the minimum level of reliability performance which is expected from 90% of all
samples. This confidence interval is based on the statistics of the distribution of failures. The assumed distribution of
failures is exponential. This particular distribution is commonly used in describing useful life failures. Refer to
MIL-STD-690B for details on this methodology.
3. A failure is any LED which does not emit light.
