   Transformers on DC are already a solved problem with various switched-mode converters that can boost or decrease voltages at will. In fact, many AC-DC supplies (phone charger, etc.) are already using such converters, first rectifying the in

   > Heating elements can run on DC more or less unmodified. ..but to get the same power (heat) output you need more current in a low voltage DC system. And power loss in the supply cables scales with the square of current, so you'll n

   Speculation: Perhaps they are trying to distinguish themselves from the "cheaper" products by using the "new" blue LEDs? IIRC the technology for them was figured out much later than green or red, so maybe there is a bit
