The second method uses LEDs in conjunction with a phosphor.

Or, more simply, using LEDs that all have the same forward voltage.

The advantages of using LEDs as light source are their compactness, long life, power efficiency and price.

Using white LEDs as the backlight improves this further.

However, most shows use LEDs only for lighting cycloramas, or as top, side or back light.

Using strong red LEDs on the skin significantly reduced wrinkles.

Some guitar players have used LEDs in the fretboard to produce unique lighting effects onstage.
