You mentioned that you carry. Meaning you sell them or you buy them and carry them in your inventory? I bought some LEDs from Holiday Light Source and I was disappointed in the look and brightness of the rectified bright white LEDs. I am not sure if it was because they were just not good from them or if that is just the way LEDs look.We carry two different brands, both which are rectified, one has sealed bulbs, the other you can make custom strands with by moving the bulbs around. We also have the sealed sets not retified for less money. All our sets have a three year warranty and are built with heavier wire.
I am interested in finding out who you purchase them from. I paid $17 for a set of 25 C7s in LED.
