YELLOW T 1 3/4 LED, ULTRABRIGHT

Used 3 in series with 270 ohm resistor and full-wave bridge for 12 v walk light replacements. Very warm amber light, perfect for application.

These are very bright and have a warm amber output. I measured the Voltage Drop at 2.07 VDC at 20mA. I rigged one to an old LM3909 LED flasher circuit set to flash about 20 times a second and shined it down to the cats dish from the countertop. Lights up the cats dish nicely for her midnight snacks. Brighter than the white LED-115. Looks like it may be bright enough to be useful in automotive applications.

Using this to replace LED's in a electronic sign board. Driving them @ 3.3V @ 20mA. Provides a evenly diffused cone that seems slightly greater than 30 Deg. w/minimal hot spots. Didn't really expect this super performance at such a low price. Oh, nicely tinned pins and clean packaging.

These LEDs are really bright (I didn't see a voltage/current specification but am driving them with 3 volts/ 20ma and so far so good)! I'm making custom LED clusters to replace some of the amber colored incandescent parking/side marker light bulbs on my Jeep. These do the trick.

Very bright. the color is more orange than it is yellow. None the less, good quality.
