STW8C2SA - mid-power price, 1W diode

2-chips encapsulated in a plastic package offer over 110lm of flux (@150mA, 5000K. 6.6V) at a mid-power LED price.
Best lm/$ ratio - 1W+ of power for the demanding, but cost effective applications.

STW8Q14D - new improved 5630 LED from Seoul Semiconductor

Up to 200lm/W efficacy (@65mA, 25degC, 5000K) and up to 200mA driving current in the industry standard package. Bigger slug lowers the thermal resistance (to 15), which results in longer lifetimes and allows to use smaller heatsinks.
