LED-eshop.de WW-550WD Warm White LED
Received 11-13-08, tested 11-26-08

This is a 5mm round through-hole LED that emits a yellowish-white ("warm white") light. I do not have an instrument for measuring color temperature, but it looks like ~3,500K to me. This LED comes in a diffused body, not transparent water-clear like many others.


Beam photograph on the test target at 12".
Intensity measures 3,150mcd on a Meterman LM631 light meter.
Vf (forward voltage) is 3.064 volts at 19.28mA.
Viewing angle is 50.

LED-eshop.de R-630-590RD Red LED
Received 11-13-08, tested 11-25-08

This is a 5mm round through-hole LED that emits a red light. Peak wavelength appears to be 634.6nm - *QUITE CLOSE* to where it ought to be. This LED comes in a red-tinted diffused body, not transparent water-clear like many others.


Beam photograph on the test target at 12".
The image is so faint because this is a very wide-angle *RED* lamp.
Intensity measures 250mcd on a Meterman LM631 light meter.
This is a wide viewing angle LED, and if I've told you once, I've told you 1,053,000 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values.

Vf (forward voltage) is 1.863 volts at 19.28mA.
Viewing angle is 90.

LED-eshop.de G-525-570/D Green LED
Received 11-13-08, tested 11-25-08

This is a 5mm round through-hole LED that emits a pure green light. Peak wavelength appears to be 519.6nm - *VERY CLOSE* to where it ought to be. This LED comes in a transparent water-clear body, but its "lens-end" is shortened, giving it a wide viewing angle.


Beam photograph on the test target at 12".
Intensity measures 2,250mcd on a Meterman LM631 light meter.
This is a wide viewing angle LED, and if I've told you once, I've told you 2,458,770 times:
Wider viewing angles always, always, ALWAYS equal lower mcd values.

Vf (forward voltage) is 2.926 volts at 19.28mA.
Viewing angle is 90.
