All the LED lights I have used seem to cast a very harsh light with many shadows, they seem to give plenty of light but not light that helps you see! Incandescent lamps seem to be much more effective, is it just me?

Paul.

Not just you. Incandescents have a nicer light because it's a warmer, natural color and covers a wider frequency range. LED's, by the nature, produce a narrower frequency range of light. White LED's are actually blue and use colored phosphors to produce the desired color. At least LED's are better than fluorescent…yuck.

Whilst your comments are generally valid, Mike … It’s worth noting that some of the modern High CRI LEDs are getting very close to the preferred ‘black body’ radiation spectrum.

This is good news!

Just located one of my old posts on another forum:

All rather impressive.
