EFFICIENCIES

Total System Efficiency

108 lm/W

The performance of each component of a luminaire is

demonstrated through its efficiencies, which together

determine the total system efficiency of the product. The

output of the LED chip is first multiplied by the optical and

thermal efficiencies to calculate the Luminaire efficiency.

However, this calculation does not consider the driver

efficiency. To determine the overall efficiency of the system,

the Luminaire efficiency must be multiplied by the driver

efficiency, which accounts for all losses in the system.

LED LIFETIME

LED Lifetime

>60000 hrs

This is the Reported LED Lifetime in Hours based on TM-21.

Atom does not list the projected or calculated LED lifetime,

which is normally longer as TM-21 Addendum B explicitly

states "The Calculated and Projected Lp(Dk) are not to be

reported". This Lifetime refers to the life of a single LED

however the system life is longer since the probability and

binomial distribution of all LEDs in the system means that the

average led is performing above the specification and

compensates for the LEDs falling below.

This rating defines the performance of the led within its

lifetime. L relates to lumen depreciation, where the

proceeding number gives the resultant lumen output at the

end of it reported lifetime. L70, would mean 30% lumen

depreciation which means 70% of its initial output and is

tested accordingly to TM-21. The B part refers to failures,

which can be define as the percentage of LEDs which fall

below the L value in the projected lifetime. A value of B10

refers to 10% failure and a value of B50 refers to 50% failure.

After the defined lifetime, the system will reach the defined

lumen depreciation and the average led failures is defined by
