I don't think LED is the answer for this one

[The Natural Philosopher]

Why not build a 230VDC power supply then?

So you need training in order to change reality, wow what news is that.

It;s all about power factors adn in tensities and cooling. As LEDs are very suseptable to heat and run more efficintly at their brightest it;s better to just flash them off and on rathe rthan try to maintain a high brightness. This principle was used in the first radar systems to bleep and allow the valves to not burn out.

[Dave Plowman (News)]

You certainly need some training about camera technology.
