Question: LEDs have been developed by Seoul Semiconductor that can operate on AC power without the need for a DC converter. For each half-cycle, part of the LED emits light and part is dark, and this is reversed during the next half-cycle. The efficacy of this type of HP-LED is typically 40 lm/W. A large number of LED elements in series may be able to operate directly from line voltage. In 2009, Seoul Semiconductor released a high DC voltage LED, named as 'Acrich MJT', capable of being driven from AC power with a simple controlling circuit. The low-power dissipation of these LEDs affords them more flexibility than the original AC LED design.
Is there an answer to this question: What is so good about ac powered HP-LEDs?

Answer: more flexibility

Question: With the financial expansion, trading rights became more jealously guarded by the commercial elite. Towns saw the growing power of guilds, while on a national level special companies would be granted monopolies on particular trades, like the English wool Staple. The beneficiaries of these developments would accumulate immense wealth. Families like the Fuggers in Germany, the Medicis in Italy, the de la Poles in England, and individuals like Jacques Coeur in France would help finance the wars of kings, and achieve great political influence in the process.

Question: In Buddhist practice, it is said that while samatha meditation can calm the mind, only vipassana meditation can reveal how the mind was disturbed to start with, which is what leads to insight knowledge (jnana; Pali nana) and understanding (prajna Pali panna), and thus can lead to nirvana (Pali nibbana). When one is in jhana, all defilements are suppressed temporarily. Only understanding (prajna or vipassana) eradicates the defilements completely. Jhanas are also states that Arahants abide in order to rest.
