We just received a shipment of 110, 120 and 130 Lumen 119 Nichia LEDs. I decided I wanted to try them out, so I replaced 48 of 60 of the LEDs in a Harbor Freight 60 LED solar security light. The replacement took about 30 Minutes to complete.

The Nichia 119 LEDs are available at a very low price here: http://www.madscientisthut.com/Shopping/agora.cgi?Components&user4=Nichia%201W%20LED

Here is a picture of the board with ten of the LEDs replaced (see red circle in picture):

 

 

 

 

 

 

 

 

 

 

Here it is being tested with the first ten LEDs

 

 

 

 

 

 

 

 

 

Here it is with 48 of the LEDS replaced, I had to turn the ISO way down to 64 and exposure to 1/210th of second on the camera to keep it from overloading the CCD as you can see in the next two images.

 

 

 

 

 

 

 

 

 

 

I can feel heat coming off of the LEDs when this is on now. Wow is it bright!!!! (camera ISO setting at 200, still pretty low, exposure was 1/70th second)
