4W LED Adjustable Downlight (24V)
Total System Efficiency | 95 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 | 50000 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. |

We needed to replace thimble down lights because they allowed dust from attic to come through. And these light were the answer. Clean fit and being recessed you don’t have those blaring lights in your face. We’re very happy with the change over
Arrived safe. Excellent quality. Solid base. Look fabyin our spare bedroom. So happy with the 2 we ordered we got another 2.
White. Nice lighting. Very happy.
Other than having to wait a couple of months for the lamp shade it was the perfect quality, size, linen colour and just what l wanted...
I love my quirky bedside lamp (I've named him Henry). Arrived packaged well and easy to attach the shade to the base. Exactly as expected and works great! Best Buy Lighting were also great communicators and I would highly recommend.
