LED-eshop.de W-1010 white LED
Received 12-31-07, tested 01-06-08
This is a 10mm round through-hole LED that emits a mainly white light with a cool color temperature (est. 6,500K). The beam is very narrow, and consists of a magnified image of the LED's die (light-emitting region), surrounded by a circular, yellowish-white corona with a relatively sharp perimeter.


Photograph of the beam image at several feet; this allows the actual beam structure to be seen.
The green spots are from a Laser Stars unit, and may be ignored.

This LED has a water-clear transparent epoxy body, and has a viewing angle of 10°.
As I said earlier, it comes in a 10mm body, not a 5mm one like many other common LEDs.


Beam photograph on the test target at 12".
Intensity measures 27,200mcd on a Meterman LM631 light meter.
Vf (forward voltage) is 3.259 volts at 30mA.
Viewing angle is avertised at 10°

LED-eshop.de G-525-1016/B green LED
Received 12-31-07, tested 01-04-08
This is a 10mm round through-hole LED that emits radiation peaking at 515.5nm in the green region of the spectrum. The light appears as a bright, slightly whitish-green.

This LED has a water-clear transparent epoxy body, and has a viewing angle of 10°.
As I said earlier, it comes in a 10mm body, not a 5mm one like many other common LEDs.


Beam photograph on the test target at 12".
That white area at the center of the beam is a camera artifact, and does not exist in reality.
Intensity measures 59,500mcd on a Meterman LM631 light meter.
Vf (forward voltage) is 3.046 volts at 30mA.
Viewing angle is avertised at 10°

LED-eshop.de IR-670-560WD deep red LED
Received 12-31-07, tested 01-03-08, repeat spectroscopy performed 10-15-09
This is a 5mm round through-hole LED that emits radiation peaking at 670nm in the very deep red region of the spectrum. The light appears as a deep cherry red; not quite as deep a red color as the light from the IR-690-560WD LED shown directly below.

This LED has a milky-white diffused epoxy body, so the beam angle is wider than usual for a very deep red LED at 60°.

Vf (forward voltage) is 1.907 volts at 50mA.

LED-eshop.de IR-690-560WD very deep red LED
Received 12-31-07, tested 01-03-08, repeat spectroscopy performed 10-15-09
This is a 5mm round through-hole LED that emits radiation peaking at 690nm in the very deep red region of the spectrum. The light appears as a deep cherry red; not quite as deep a red color as the light from the IR-720-560WD LED shown directly below.

This LED has a milky-white diffused epoxy body, so the beam angle is wider than usual for a very deep red LED at 60°.


Because the LED is diffused and because it is a very deep red, a beam photograph at the standard distance of 12" will not be possible.
So this beam photograph was taken at ~8" (20.3cm).
Vf (forward voltage) is 1.896 volts at 50mA.
Viewing angle is avertised at 60°

LED-eshop.de IR-720-560WD near-infrared LED
Received 12-31-07, tested 01-02-08, repeat spectroscopy performed 10-15-09
This is a 5mm round through-hole LED that emits radiation peaking at 720nm in the NIR (near-infrared). The light appears as a deep cherry red.

This LED has a milky-white diffused epoxy body, so the beam angle is wider than usual for a NIR LED at 60°.


Because the LED is diffused and because it is NIR, a beam photograph will not be possible.
So this photograph of the LED in my LED tester next to the test target (proximity approximately 1.5" (3.8cm)) will have to suffice.
Vf (forward voltage) is 1.742 volts at 30mA.
Viewing angle is avertised at 60°

LED-eshop.de IR-905-560WD near-infrared LED
Received 12-31-07, tested 01-02-08, repeat spectroscopy performed 10-18-09
This is a 5mm round through-hole LED that emits radiation peaking at 905nm in the NIR (near-infrared). It is essentially invisible, but a few viewers may be able to discern an extremely faint, very dim, very deep cherry red glow when they look directly into the lamp.

This LED has a milky-white diffused epoxy body, so the beam angle is wider than usual for a NIR LED at 60°.

Because the LED is diffused and because it is NIR, a beam photograph will not be possible.
Vf (forward voltage) is 1.321 volts at 30mA.
Beam angle is avertised at 60°

As you can see, the PC2000-ISA spectrometer I used the first time around was the correct instrument for this job.



LED-eshop.de IR-770-560WD near-infrared LED
Received 12-31-07, tested 01-01-08, repeat spectroscopy performed 10-15-09
This is a 5mm round through-hole LED that emits radiation peaking at 770nm in the NIR (near-infrared). Some people may not be able to see this wavelength, but most should see it as a very dim, deep cherry red glow.

This LED has a milky-white diffused epoxy body, so the beam angle is wider than usual for a NIR LED at 60°.


Because the LED is diffused and because it is NIR, a beam photograph will not be possible.
So this photograph of the LED in my LED tester will have to suffice.
Vf (forward voltage) is 1.590 volts at 30mA.
Viewing angle is avertised at 60°

LED-eshop.de IR-740-560WD near-infrared LED
Received 12-31-07, tested 01-02-08, repeat spectroscopy performed 10-15-09
This is a 5mm round through-hole LED that emits radiation peaking at 740nm in the NIR (near-infrared). It should be visible to most viewers as a somewhat dim, deep cherry red.

This LED has a milky-white diffused epoxy body, so the beam angle is wider than usual for a NIR LED at 60°.


Because the LED is diffused and because it is NIR, a beam photograph will not be possible.
So this photograph of the LED in my LED tester will have to suffice.
