We got light on luminance of universal LEDs

One example for all - we compared super bright red LED Kingbright SR-J4 with a standard type of the same producer.

This is an archive article published 05/02/2014. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Comparison of features is usually the most exact method how to compare two similar components. But what´s the result in praxis? At such a parameter like luminous intensity, we´re probably the most interested in a subjective perception - how it shines in a real design. That´s why we decided to bring you a direct comparison. On the left side, there´s always a high efficient LED from the SR-J4 series, namely L7104SRC-J4 and a standard quality LED from the L-934SRC-C series is on the right side (it´s worth to mention that even this type has a higher than standard luminous flux). LEDs were connected in series, so they were driven by the same current. We used two common values - 1 mA and 10 mA.

And a conclusion? Both types have their advantages - the standard type mainly in the price. In respect to a very affordable price of a more efficient type, it´s more advisable to use this new type SR-J4 as well as other similar, for example series ZGK, SRY and other. In result, an efficient type will always bring a lower power consumption, longer battery life, trouble-free connection to logic circuits etc.

Detailed information will provide you the Kingbright SR-J4, ZGK and SYK datasheets. Type „C“ at marking of many LEDS - for example ZGCK, SYCK means a transparent package (Clear).
