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).
