Let your illuminant be measured!

Label your light source with the CFD and ensure a stronger customer loyalty.


As a manufacturer or vendor of light bulbs you can label your products with the specification of the CFD in the technical data, so that the customers gain more confidence in your product and you can offer a strong argument for a purchase decision.

 

A low optical light flicker value will position your product much better on the market!

The optical light flicker of electrically operated lamps of any kind is measured by the CFD method

 

Illuminants which are i. a. measured:

-  LED illuminants

-  fluorescent lamps (classic or compact, energy saving lamps)

-  Incadescent lightbulbs

 

These, in turn, can be operated with different supply voltages.

For example:

-  230V AC (mains voltage Europe) from 0 to 500 watts.

-  Low voltage such as 12V AC / DC from 0 to 50 watts.

 

Additionally the operating mode can be combined: With or without dimmer.

For example:

-  Phase cut (leading edge)

-  Phase cut (trailing edge)

-  PWM

 

Further requirements can be requested.

Remuneration


A specially developed processor-controlled measuring unit is used to carry out the measurements, which, in addition to evaluating the light flicker, adjusts the settings for signal sensitivity and dimming operation.

The measurement results are summarized in a report.

Aside the graphical output, the

-  light emission curve

-  the flicker base frequency

-  secondary frequencies

-  the CFD result and

-  the CFD classification

are specified.

In addition, the results of the

i. a. following measurement methods are also reported:

IES %Flicker, Flicker index

- IEEE 1789

- CAT24JA10 (UL)

- CIE TLA Pst / SVM

- Jeita / Vesa

- ASSIST Flicker Metric

The reimbursement for the effort of the measurements will very quickly be amortized even with small sales figures.

For private purposes in small samples I offer the service at the moment free of charge.
